ABSTRACT: Pulmonary artery aneurysms are rare. We describe 2 adult patients with pulmonary artery aneurysm with normal pulmonary pressure associated with bicuspid pulmonary valve and atrial septal defect. One patient presented with moderate pulmonary valve stenosis and was treated with open surgery; the other patient had a small atrial septal defect and mild pulmonary valve insufficiency and is periodically still being evaluated. Hemodynamic alterations associated with a pulmonary artery aneurysm are described; the influence of additional volume overload and intrinsic wall abnormalities in pulmonary valvular lesions as potential triggers for the development of these aneurysms are analyzed and therapeutic strategies are discussed.

ABSTRACT: Following publication of our article [Lampropoulos et al., Cardiovascular Ultrasound 2012, 10:5] the authors noted that the legends for Figure 1 and Figure 2 were incorrect. The correct legend for Figure 1 is: Sequence analysis of systemic ventricular flow during systole and diastole in Fontan patients. The vortex from the Fontan group was consistently shorter, wider and rounder. The vortices were located at the centre of the left ventricle throughout diastole and systole and did not redirect flow in a coherent, sequential fashion as in controls. The location, shape and sphericity of the main vortices differ clearly from controls in all cardiac cycle [early diastole(A), late diastole(B), ejection (C)]. The correct legend for Figure 2 is: Sequence analysis of systemic ventricular flow during systole and diastole in controls. The vortex from the control group was compact, elliptically shaped, and located apically. The location, shape and sphericity of the main vortices differ clearly from the Fontan group in all cardiac cycle [early diastole(A), late diastole(B), ejection (C)]. It was also noted the legends for the Additional file 1 and Addition file 2 were also incorrect: The correct legend for Additional file 1 is: The flow patterns of a 38 year old female without cardiac abnormalities The correct legend for Additional file 2 is: The flow pattern of a 29 year old male with Fontan circulation. The authors would like to apologize for any inconvenience caused by this error.

ABSTRACT: Flow patterns in univentricular hearts may have clinical value. Therefore, it is our objective to asses and characterize vortex flow patterns with Fontan circulation in comparison with healthy controls.
Twenty-three patients (8 Fontan and 15 normal patients) underwent echocardiography with intravenous contrast agent (Sonovue®) administration. Dedicated software was used to perform particle image velocimetry (PIV) and to visualize intracavitary flow in the systemic ventricles of the patients. Vortex parameters including vortex depth, length, width, and sphericity index were measured. Vortex pulsatility parameters including relative strength, vortex relative strength, and vortex pulsation correlation were also measured.
The data from this study show that it is feasible to perform particle velocimetry in Fontan patients. Vortex length (VL) was significantly lower (0.51 ± 0.09 vs 0.65 ± 0.12, P = 0.010) and vortex width (VW) (0.32 ± 0.06 vs 0.27 ± 0.04, p = 0.014), vortex pulsation correlation (VPC) (0.26 ± 0.25 vs -0.22 ± 0.87, p = 0.05) were significantly higher in Fontan patients. Sphericity index (SI) (1.66 ± 0.48 vs 2.42 ± 0.62, p = 0.005), relative strength (RS) (0.77 ± 0.33 vs 1.90 ± 0.47, p = 0.0001), vortex relative strength (VRS) (0.18 ± 0.13 vs 0.43 ± 0.14, p = 0.0001) were significantly lower in the Fontan patients group.
PIV using contrast echocardiography is feasible in Fontan patients. Fontan patients had aberrant flow patterns as compared to normal hearts in terms of position, shape and sphericity of the main vortices. The vortex from the Fontan group was consistently shorter, wider and rounder than in controls. Whether vortex characteristics are related with clinical outcome is subject to further investigation.

ABSTRACT: Doubly committed ventricular septal defect (dcVSD) is the least common type of VSD. Because published studies are rather scarce, this study aimed at evaluating the midterm outcome of dcVSDs.
The records of all patients registered in the database of Paediatric and Congenital Cardiology, University Hospitals Leuven, with a dcVSD at 16 years of age were reviewed. Clinical, electrocardiographic and transthoracic echocardiographic changes from baseline, defined as of the age of 16 years, until the latest follow-up were compared.
Thirty-three patients (20 males, median age 26 years, interquartile range 12) were followed for a median time of 7.9 years (interquartile range 9.8, time range 2-25.9). No deaths occurred. In 15 patients (45%), the defect remained patent at baseline. During follow-up, two spontaneous closures (13%) occurred. Eighteen patients (55%) required closure before the age of 16 years. Five (28%) needed reoperation. In the dcVSD closure group, left ventricular ejection fraction decreased from 69 ± 12 to 61 ± 6% (p = 0.028). No significant changes in pulmonary arterial hypertension were noticed.
Patients with persistently patent dcVSD remained nearly event free during follow-up. Event-free survival after dcVSD closure was markedly lower. These patients developed reduced left ventricular function and had a high risk of reintervention.

ABSTRACT: Congenital heart defects (CHD) are associated with the recurrent 10q22q23 deletion syndrome and with partially overlapping distal 10q23.2.q23.31 microdeletions. We report on a de novo intragenic deletion of the BMPR1A gene in a normally developing adolescent boy with short stature, delayed puberty, facial dysmorphism and an atrioventricular septal defect. Based on this finding, complemented with computational prioritization data and molecular evidence in literature, the critical region for CHD on 10q23 can be downsized to a single gene, BMPR1A. Although loss-of-function mutations in BMPR1A typically result in juvenile polyposis syndrome, none of the patients with the typical 10q22q23 microdeletion syndrome, comprising this gene, were reported to have juvenile polyposis thus far. We reason that, even in the absence of juvenile polyposis syndrome, sequencing and copy number analysis of BMPR1A should be considered in patients with (atrioventricular) septal defects, especially when associated with facial dysmorphism and anomalous growth.

ABSTRACT: Several patients with trisomy 21 developed the Eisenmenger syndrome (ES) because the underlying congenital heart defect was not corrected. However, little is known about their prognosis.This study aimed at (1) identifying risk factors for worse prognosis in ES patients, and (2) evaluating whether outcome of ES patients with trisomy 21 differs from ES patients without trisomy 21.
Data on all Eisenmenger patients in follow-up at the paediatric and adult congenital heart disease clinic of the University Hospitals Leuven were collected for retrospective analysis. Regression analysis was performed where applicable and survival rate was compared between patients with and without trisomy 21.
One hundred thirty-four patients (mean age at latest follow-up 33.2 +/- 13.6 years, 41.8% male, 44.8% trisomy 21) were included in the study. Complex lesions, right heart failure, impaired renal function, lower transcutaneous saturation and lower body mass index were predictive of impaired outcome. Mean survival of the global ES group was 44.9 +/- 2.2 years. However, long-term survival of trisomy 21 patients was not statistically different from patients without trisomy 21 (mean survival 44.5 +/- 2.6 years vs 44.5 +/- 2.9 years, respectively, P = 0.80, log rank test).
Long-term survival is markedly reduced in Eisenmenger patients. Complex lesions, right heart failure, impaired renal function, lower transcutaneous saturation and lower body mass index were related to worse prognosis. However, survival of trisomy 21 patients did not differ from patients without trisomy 21.

ABSTRACT: This study aimed at determining the effect of percutaneous ASD closure on the AV conduction. Percutaneous closure of ostium secundum atrial septal defects (ASDs) has been widely accepted and has become the standard treatment of this malformation. However, some complications have been reported. Because of the close proximity between the discs of the device and the atrioventricular (AV) node, atrioventricular conduction disturbances (AVCD) are a likely complication.
From the database of congenital heart disease, 46 patients (mean age 54 +/- 12 y) who underwent percutaneous ASD closure and 46 patients who underwent a percutaneous patent foramen ovale (PFO) closure were matched according to age, gender and follow-up time. Demographic, clinical, biochemical, and ECG variables were compared. Before closure, the PR interval in the ASD group was significantly longer than in the PFO group (169 +/- 22 ms versus 158 +/- 25 ms, P= 0.031), which persisted after a mean follow-up time of 4.5 years (180 +/- 39 ms versus 163 +/- 23 ms, P= 0.007). PR interval increased significantly from closure to latest follow-up in the ASD (P=0.038), but not in the PFO group (P=0.058).
ASD patients presented with significantly longer PR interval than PFO patients before closure. In contrast with the PFO group, the PR interval increased in the ASD group after medium-term follow-up. These findings indicate the need for further follow-up after ASD repair in order to detect potential late AVCD.

ABSTRACT: Adolescents with congenital heart disease (CHD) must take responsibility for their life and care. This requires that they have sufficient knowledge about their heart disease, treatment, and preventive measures. Thus, CHD-related education should be directed to adolescents. Research on adolescents' understanding and knowledge of CHD is limited. It is unknown what adolescents with CHD know about their heart defect, treatment, and preventive measures necessary to avoid complications. We addressed these questions in a descriptive cross-sectional study of 91 adolescents with CHD (53% males; median age 17 years). In the present study, we assessed the subjects' knowledge of CHD using the Leuven Knowledge Questionnaire for Congenital Heart Disease. The results showed that the patients had adequate knowledge (>80% correct answers) about the need for regular follow-up, their required diet, past treatment, and dental practices. They had moderate knowledge (50% to 80% correct answers) about the frequency of follow-up, occupational choices, medication regimen, and sexual activities. However, the patients had poor knowledge (<50% correct answers) of the name of their heart defect; the reasons for follow-up; the effects of competitive sports; the symptoms that reflect deterioration of their heart disease; the definition, characteristics, and risk factors of endocarditis; the possibility of recurrent episodes of endocarditis during their lifetime; the effect of smoking and alcohol on their heart disease; the hereditary nature of their condition; the suitability of intrauterine devices as contraceptives; the appropriateness of oral contraceptives; and the risks of pregnancy. In conclusion, the results of the present study have showed that the level of knowledge of adolescents with CHD has significant gaps.

ABSTRACT: Ebstein's anomaly, characterized by an apical displacement of the tricuspid valve into the right ventricle, occurs in approximately 1/200,000 live births. Because long-term follow-up data of adults with Ebstein's anomaly are scarce, we evaluated the outcome of our Ebstein's anomaly patients.
All patients >16 years and registered in the congenital heart disease database of our hospital with isolated Ebstein's anomaly were selected for the study. Records were reviewed for outcome.
Forty-nine patients (21 males, mean age at diagnosis 29.1 ± 20.7 years) were followed for a mean time of 11.4 years (range 1.1-32.4). Twenty-five patients (51%) underwent tricuspid valve surgery (16 valvuloplasty and 9 valve replacement). Eight patients (32%) required redo tricuspid valve surgery. Twenty-six patients (52.1%) exhibited supraventricular arrhythmia, and the typical Wolff-Parkinson-White syndrome occurred in 15 patients (31.2%). Seventeen patients (34.7%) underwent ablation therapy and 5 patients (10.4%) required pacemaker implantation.
Half of the patients with Ebstein's anomaly needed tricuspid valve surgery and redo surgery was not uncommon. Supraventricular arrhythmia occurred frequently and ablation therapy was often indicated. Careful follow-up is obligate, as some complications occur for the first time in adulthood.

ABSTRACT: More and more children, who suffered from Kawasaki disease in childhood, reach today adulthood. The future perspectives of these patients are not yet well defined, therefore, we wanted to determine mid-term outcome of our Kawasaki patients.
All patients with the diagnosis of Kawasaki disease were selected from the database of paediatric and congenital cardiology of our hospital. The records were reviewed for disease characteristics and follow-up data. Descriptive statistics were performed.
Thirty-five patients were included (18 boys, median age at diagnosis 1.9 years, range from 0.4 to 12.2 years). In 94% of the cases, the left coronary artery was affected, whereas in 58% the right coronary artery was involved in the disease process. In three patients the left ventricular ejection fraction worsened below 50%. One patient underwent a balloon dilatation and stenting of a coronary artery, and in another patient inotropic support was needed. Aspirin was given in all, sandoglobulin in thirty patients; in 10% of the cases corticosteroids were administered. The active disease process terminated after a median of 0.5 months, ranging from 0.1 to 2.0 months. The patient cohort was followed for a median of 4 years (range from 0.1 to 17.7 years). During this follow-up time, no reoccurrences, no significant arrhythmias, and no deaths occurred. In all patients, the left ventricular ejection fraction remained normal or normalized. However, at the latest follow-up, 43% was still treated with a low dose of aspirin.
The mid-term outcome of patients who suffered from Kawasaki disease during childhood is excellent. However, almost half of them were treated with oral aspirin during follow-up.

ABSTRACT: Intra-cardiac echocardiography (ICE) is used to guide percutaneous interventions on the atrial septum. However, ICE catheters are expensive. We questioned the impact of the use of ICE catheters on hospitalization costs for patent foramen ovale (PFO) or atrial septal defect (ASD) closure.
Patients, scheduled for atrial septal closure, were randomly selected to use the AcuNav catheter (Biosense Webster Inc, Diamond Bar, CA, US) on top of the standard procedure (three or two days of hospitalization, procedure with transoesophageal echocardiography (TEE) and general anaesthesia). The AcuNav catheter was provided for free and the total hospitalization cost for each patient was calculated by verification of the bills, sent to the patient and the national health insurance. This was compared with a fictive hospitalization cost when ICE alone would have been used (three or two days of hospitalization, procedure without TEE, and local anaesthesia). Feasibility and safety were also evaluated. Three PFOs and two ASDs were successfully closed (3F/2M, age 55 +/- 12 years). The total hospitalization cost for a standard closing procedure was EUR 9345 +/- 132 and EUR 9303 +/- 132 for three and two days of hospitalization, respectively. With a free ICE catheter and no general anaesthesia, hospitalization cost lowered to EUR 8464 +/- 131 and EUR 8422 +/-131, respectively. Cost saving would be EUR 881 +/- 3, but the price of a single-use ICE catheter varies between EUR 2000 and 2500. In all patients, adequate images were obtained and no complications related to the ICE catheter occurred.
Single-use ICE catheters remain expensive in percutaneous ASD or PFO closure. However, general anaesthesia might be avoided, which could open a discussion on cost savings.

ABSTRACT: The number of adolescents and young adults with congenital heart defects, including ventricular septal defect (VSD), increases continuously. We evaluated the mid-term outcome of small and unclosed perimembranous VSDs (pmVSDs). All patients with a known unrepaired pmVSD at 16 years of age were selected from our database. The clinical, electrocardiographic, and echocardiographic changes between baseline and the latest follow-up examination were compared. A total of 220 patients (119 males, median age 18 years, interquartile range 7) could be included. During a median follow-up of 6 years (interquartile range 4, range 38), 2 patients died (1%; 1 from sudden death and 1 from end-stage heart failure). Endocarditis occurred in 8 patients (4%). One patient required pacemaker implantation (0.5%) and one required implantable cardioverter-defibrillator implantation (1%). Fifteen patients (7%) required a closing procedure. In 8 patients (4%), the pmVSD closed spontaneously. In the remaining 203 patients (93%), the QRS morphology changed in 5% and 1% lost sinus rhythm (p = 0.0001 and p = 0.015, respectively). The left ventricular ejection fraction and stroke volume index increased from 62 + or - 7% to 67 + or - 8% and from 41 + or - 11 to 44 + or - 15 ml/m(2) (p = 0.0001 and p = 0.035, respectively), the end-systolic diameter decreased, and the end-diastolic diameter did not change. Finally, patients with an open pmVSD developed more pulmonary arterial hypertension during follow-up (from 3% to 9%, p = 0.002). In conclusion, mid-term follow-up of adolescents and young adults with a small and unrepaired pmVSD was not uneventful. Some patients required intervention, but in others, spontaneous closure occurred. Electrocardiographic and structural changes were noticed, for which the clinical significance needs to be determined.

ABSTRACT: Whatever the technique used for surgical or endovascular repair of a coarctation of the aorta (CA), long-term complications might occur. Aneurysm formation after patch angioplasty is not uncommon and may lead to a life-threatening condition. Therefore, we were interested in the long-term results of different types of tube grafts, from which a lower degree of dilatation is expected.
All patients, currently older than 16 years, who underwent (redo) surgery for CA, and in whom a tube graft was inserted, were selected from the database of congenital heart disease of our hospital. Follow-up data were collected by reviewing the patients' files. The degree of graft dilatation was calculated for each patient. Fifty-three patients (41 males, median age 33.1 years, Q1-Q3 29.9-40.2 years) could be included in the study, in which 20 (38%) 'Gelseal', 12 (23%) 'Gelsoft', 8 (15%) 'Gelweave', and 13 (24%) older types of grafts were used. Twenty patients underwent a primary repair and in all others a tube graft was implanted after a previous patch angioplasty. The median graft diameter (manufacturer size) at implantation was 20 mm (Q1-Q3 16-22 mm). The median follow-up time of the grafts was 13.1 years (Q1-Q3 9.0-17.2 years). The graft size increased to a median value of 26 mm (Q1-Q3 22-30 mm) (median 50% increase in diameter, range 0-271%, P < 0.0001). The diameter of six grafts remained unchanged during follow-up. Three deaths occurred, of whom two were cardiac-related. False aneurysms occurred in four patients, graft aneurysm in two, endarteritis in two, and graft stenosis in one.
Nearly, all tube grafts dilated up to 50% of the manufacturer diameter during follow-up. Re-interventions were inevitable in more than 10 per cent of the cases, primarily because of (false) aneurysm formation. Our series illustrates that late complications are not uncommon, so that rigorous follow-up of these CA patients remains mandatory.

ABSTRACT: A significant number of patients with pulmonary hypertension are resistant to medical therapy. We wanted to evaluate whether the modified technique of stent fenestration of the interatrial septum would be feasible and safe, and offer clinical benefit.
The medical records of all patients with pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension who underwent a stent fenestration of the interatrial septum between 2001 and 2008 were reviewed. In all fifteen patients (12 female, mean age 48.2 +/- 20.5 years) a successful fenestration procedure could be performed. Median follow-up time between diagnosis and fenestration was 2.3 years (range from 0.5 to 18.6 years). Mean event free survival since diagnosis and after septostomy was 9.8 +/- 2.9 and 3.2 +/- 0.8 years, respectively. When one extreme outlier was excluded, the 6 min walk distance improved significantly from 309 +/- 69 m immediately before fenestration to 374 +/- 84 m, 3-4 months after fenestration (n = 8, paired t-test, P = 0.03). No stent occlusion occurred.
The modified stent fenestration technique is feasible and safe in patients with severe pulmonary hypertension. In a selected group of patients, functional capacity might improve although disease progression continues.

ABSTRACT: We previously described a potential relationship between the presence of migraine and congenital heart defects. It has been hypothesized that a genetic substrate might determine for congenital heart defects and migraine. Therefore, we wanted to study the prevalence of migraine in female patients with coarctation of the aorta (CA) and to determine predictive variables for migraine in this specific population.
All patients with CA, previously selected for the ZAHARA trial to evaluate pregnancies and outcome, were recruited from the database of congenital heart disease of the University Hospital of Leuven. These patients were contacted by phone and asked to complete a structured headache questionnaire. Based on this questionnaire, a neurologist blinded to the patients' files, diagnosed migraine without or with aura (MA- and MA+, respectively), according to the international headache criteria. Demographic, clinical, and technical data were obtained by reviewing the patients' records.
Thirty-four female patients (age 32.2 +/- 6.3 y) were included in the study. The overall prevalence of migraine in female CA patients was 38%, of which 12% were MA- and 26% MA+. No significant relationship between demographic, clinical, and technical variables and migraine could be determined, except for migraine and the number of pregnancies and smoking behaviour (univariate logistic regression; B = 1.2 and 1.9, P = 0.039 and 0.027, respectively).
In this study, we found a relatively high prevalence of migraine in female adult CA patients. We could also demonstrate a positive relationship between migraine, smoking behaviour, and the number of pregnancies. Therefore, we should pay more attention to these findings in daily practice.

ABSTRACT: A 79 year old man was admitted to the hospital with increased breathlessness and fatigue on minimal exertion, and this since a few weeks. Transthoracic and transesophageal echocardiography, followed by cardiovascular magnetic resonance imaging, demonstrated a cardiac pseudoaneurysm connected with both ventricular cavities resulting in an extracardiac left-to-right shunt, with even re-perforating into the right atrium. These findings were suggested to be sequels from an inferior myocardial infarction. Given the age and the complex characteristics of the aneurysm, conservative management was the treatment of choice. At one year follow-up the patient was still doing well.

ABSTRACT: Homografts are frequently implanted in patients with tetralogy of Fallot (TOF). However, the lifespan of homografts is shorter than that of graft recipients, thus making surgical re-intervention unavoidable. Therefore, to determine variables that could influence their survival, we retrospectively studied the survival pattern of homografts used to treat TOF.
Sixty-eight TOF patients, >14 years of age (mean age: 34 +/- 11; 71% male), were selected from our database of congenital cardiology cases. These patients underwent their first homograft implantation at a median age of 24 years (range: 14-49). The primary endpoint, homograft failure, was defined as homograft replacement or percutaneous balloon dilatation when the echocardiographic gradient reached more than 50 mmHg. Kaplan-Meier analysis revealed that the mean event-free survival time of first homografts was 14.6 years (CI, 12.9-16.2 years). The median increase in the homograft gradient was 1.1 mmHg/year (range: 0.0-22.1) for a median follow-up time of 8.4 years (range: 1.3-17.9). Stepwise regression analysis identified the homograft gradient at 1 month after surgery to be prognostic for homograft degeneration (R(2) = 0.23, beta = 0.26, P = 0.001). Immunological variables, gender, and post-operative inflammatory indicators were unrelated to the degree of homograft gradient increase. Finally, patient age at the time of first homograft implantation and previous palliative surgery was significantly associated with the gradient at 1 month (Spearman's rho = -0.41 and -0.29, respectively; P = 0.004 and 0.048, respectively).
Homograft survival in patients with TOF repair is quite good. However, some patients develop accelerated homograft degeneration. We found that the gradient of the homograft 1 month after surgery is most indicative of accelerated homograft degeneration. We hypothesize that mechanical, not immunological, factors play an important role in homograft degeneration.

ABSTRACT: Empirical evidence indicates that patients with congenital cardiac anomalies may be prone to developing coronary heart disease. Although primary prevention of ischaemic heart disease in patients with congenital heart defects is important, data on the prevalence of cardiovascular risk factors in these patients are not available. The aims of this study are therefore to describe the prevalence of risk factors for coronary heart disease in a large sample of adults with congenital cardiac anomalies, and compare this with the prevalence in the general population.
A retrospective analysis of computerized patient records.
At our outpatient clinic, all patients are examined by an advanced practice nurse and a congenital heart disease cardiologist. Data on smoking behaviour, sports participation, blood pressure, body mass index, and the diagnosis of diabetes are recorded systematically. Data on the general population were derived from national health surveys.
In a 4-year period, we collected data on 1976 individual patients. Male patients had a significantly higher prevalence of smoking and elevated blood pressure, whereas women were less engaged in sports activities and were more often obese. In comparison with the general population, our patients reported less smoking and more participation in sports, but presented more often with hypertension or diabetes. Only 20.4% of men and 21.0% of women have a fully heart-healthy lifestyle, as they presented without any risk factor.
A substantial number of patients had one or more cardiovascular risk factors. Therefore, primary prevention by strengthening educational efforts becomes critically relevant in patients with congenital heart disease, to avoid the additional burden of coronary events in this growing population of patients.

ABSTRACT: Cerebral emboli and abscesses are common complications in patients with cyanotic congenital heart disease and right-to-left shunt. Of those, a persistent left superior vena cava (LSVC) draining into the left atrium, directly or through an unroofed coronary sinus, is a rather rare finding. In order to prevent recurrent cerebral emboli and abscesses, correction of this anomaly may be recommended. We report the first case of a patient who underwent a percutaneous closure of a persistent LSVC draining into the left atrium with an Amplatzer ASD occluder.
