    ABSTRACT: Among patients with severe aortic stenosis (sAS) and preserved LVEF, those with low-flow, low-gradient sAS (LFLG-sAS) have an adverse prognosis. It has been proposed that LFLG-sAS represents an end-stage point of sAS, but longitudinal information has not been described. The aim was to determine whether LFLG-sAS represents an end-stage consequence of normal-flow, high-gradient sAS (NFHG-sAS) or a different entity. From our transthoracic echocardiogram (TTE) database, we identified patients with sAS (aortic valve area <1 cm(2)) and preserved LVEF (≥50%), and from these, patients with LFLG-sAS (stroke volume index <35 mL/m(2) and mean transvalvular gradient <40 mm Hg) who had ≥1 additional TTE within five years prior to the index TTE. Patients were age/sex/date matched 2:1 with patients with NFHG-sAS and normal-flow, low-gradient (NFLG)-sAS who also had ≥1 TTE. Included were 1203 TTEs (383 index studies and 820 preceding studies). In 78 patients with LFLG-sAS, an HG stage preceded the index TTE in only 4 (5%). During the five years preceding the index TTE, patients with LFLG-sAS developed increasing relative wall thickness (0.42 to 0.49; p<0.001) without change in LV mass index. Patients with NFHG-sAS had a marked increase in LV mass index (87 to 115 g/m(2); p<0.001). Patients with LFLG-sAS demonstrated the greatest reduction in LV end-diastolic diameters (-3 vs -1 for NFLG-sAS vs +2 mm for NFHG-sAS; p=0.001), deceleration time (-55 vs -3 vs +3 ms, respectively; p<0.01) and LVEF (-4 vs 0 vs 0%, respectively; p=0.01). LFLG-sAS is a distinct presentation of sAS preceded by a unique remodelling pathway and is uncommonly preceded by an HG stage. Published by the BMJ Publishing Group Limited.

    ABSTRACT: -Most patients with repaired tetralogy of Fallot (TOF) require pulmonary valve replacement (PVR), but the evaluation for and management of ventricular arrhythmia remains unclear. This study is aimed at clarifying the optimal approach to this potentially life-threatening issue at the time of PVR. -A retrospective analysis was performed on 205 patients with repaired TOF undergoing PVR at our institution between 1988 and 2010. Median age was 32.9 (range 25.6 years). Previous ventricular tachycardia (VT) occurred in 16 patients (8%) and 37 (16%) had left ventricular (LV) dysfunction, defined as LV ejection fraction <50%. Surgical right ventricular outflow tract cryoablation was performed in 22 patients (10.7%). The primary outcome was a combined event including VT, out-of-hospital cardiac arrest, appropriate implantable cardioverter-defibrillator therapy and sudden cardiac death. Freedom from the combined event at 5, 10, and 15 years was 95, 90, and 79%, respectively. In the first year following PVR, 2 events occurred. Conversely, in the 22 patients who underwent surgical cryoablation, a single event occurred 7 years after PVR. A history of VT and LV dysfunction were associated with higher risk for the combined event (HR 4.7, p=0.004 and HR 0.8, p=0.02 respectively). -Patients with repaired TOF undergoing PVR with history of VT and/or LV dysfunction appear to be associated with a higher risk of arrhythmic events after operation. Events in the first year after PVR are rare, and in select high risk patients, surgical cryoablation does not appear to increase arrhythmic events and may be protective.

    ABSTRACT: Background: Novel echocardiographic techniques based on myocardial deformation have not been extensively evaluated to assess right ventricular (RV) and left ventricular (LV) response after pulmonary valve replacement (PVR) in patients with repaired tetralogy of Fallot. Methods: Between 2003 and 2012, 133 patients undergoing first-time PVR after tetralogy of Fallot repair underwent echocardiographic assessment at Mayo Clinic. The last echocardiogram before PVR and 1 year after surgery were retrospectively analyzed with Velocity Vector Imaging. Results: Mean age at PVR was 35.5 +/- 16.2 years (54% women). Longitudinal peak systolic strain and strain rate before PVR were low: for the left ventricle, 14.8 +/- 3.5% and 0.8 +/- 0.2 sec(-1), and for the right ventricle, -16.2 +/- 4.1% and -0.9 +/- 0.3 sec(-1), respectively. There was no significant change in either parameter after surgery. A close correlation between LV and RV deformational parameters was found before PVR and was maintained after surgery. In the multivariate analysis, patients with better LV and RV peak systolic strain preoperatively were found to have better LV and RV peak systolic strain after surgery (P = .004 and P = .006, respectively). However, patients with the most improvement in deformation were those with worse RV function preoperatively (P = .002). Mean New York Heart Association class at early follow-up improved from 2.2 +/- 0.8 to 1.2 +/- 0.6 (P < .0001); RV peak systolic strain was the only factor associated with symptomatic improvement. Conclusion: LV and RV systolic and diastolic deformational parameters were decreased in patients with repaired tetralogy of Fallot undergoing PVR, and there was no significant change after surgery. However, preoperative systolic deformational parameters were predictive of postoperative ventricular function and New York Heart Association class after PVR and may be helpful to identify optimal timing for surgical intervention in this cohort.

    ABSTRACT: Objective To evaluate patients with Marfan syndrome and mitral valve regurgitation undergoing either valve repair or replacement and to compare them to patients undergoing repair for myxomatous mitral valve disease. Methods We reviewed the medical records of consecutive patients with Marfan syndrome treated surgically between 03/17/1960 and 09/12/2011 for mitral regurgitation and performed a subanalysis of those with repairs compared to case-matched patients with myxomatous mitral valve disease who had repairs (03/14/1995-07/05/2013). Results Of 61 consecutive patients, 40 patients underwent mitral repair and 21 underwent mitral replacement (mean [SD] age, 40 [18] vs 31 [19] years; P=.09). Concomitant aortic surgery was performed to a similar extent (repair, 45% [18/40] vs replacement, 43% [9/21]; P=.87). Ten-year survival was significantly better in Marfan syndrome patients with mitral repair vs replacement (80% vs 41%; P=.01). Mitral reintervention did not differ between mitral repair and replacement (cumulative risk of reoperation, 27% vs 15%; P=.64). In the matched cohort, ten-year survival after repair was similar for patients with Marfan syndrome and myxomatous mitral disease (84% vs 78%; P=.63), as was cumulative risk of reoperation (17% vs 12%; P=.61). Conclusions Patients with Marfan syndrome and mitral regurgitation have better survival with repair than with replacement. Survival and risk of reoperation for patients with Marfan syndrome were similar to those for patients with myxomatous mitral disease. These results support the use of mitral valve repair in patients with Marfan syndrome and moderate or more mitral regurgitation, including those having composite replacement of the aortic root.

    ABSTRACT: Surgical pulmonary valve replacement (PVR) in previously repaired tetralogy of Fallot (TOF) is frequently required. There are few data in large series of patients with long-term follow-up. Our aim was to review our 40-year experience with PVR after TOF repair, and to evaluate prognostic factors for reintervention and death. Between 1973 and 2012, 278 patients with repaired TOF (53% males; 31.4±16.4 years of age) underwent first PVR 24±13 years after TOF repair. Three or more prior operations were performed in 17% of the patients and 42% were in NYHA class III/IV. PVR types included porcine (n=211), pericardial (n=37), homograft (n=27) and mechanical (n= 3). Early mortality was 1.4%. Mean follow-up was 7.3±6.8 years (maximum, 34 years). Overall survival at 5-10-15 years was 93%-83%-80% compared with 99%-97%-95% in a gender and age matched U.S. population, p<0.001. Independent risk factors for death were older age at complete repair (HR 1.2, p=0.012), ≥ 3 previous cardiac operations (HR 1.9, p = 0.019), NYHA class III/IV at PVR (HR 2.7, p=0.019) and large body surface area at PVR (HR 1.9, p<0.001). Reintervention after initial PVR occurred in 25 patients. Overall 5-10-15 year freedom from pulmonary valve reintervention was 97%-85%-75%, respectively. Multivariate analysis demonstrated older age at PVR to be protective from reintervention (HR 0.7, p<0.001). In conclusion, PVR is a safe operation with a low rate of reintervention in repaired TOF. The total number of cardiac operations, surgical timing, and the NYHA classification prior to PVR are important prognostic factors.

    ABSTRACT: The objective of this review was to describe the clinical characteristics, risk factors, and outcomes of infective endocarditis (IE) in pregnancy and the postpartum period. We conducted a systematic review of Ovid MEDLINE, Ovid Embase, Web of Science, and Scopus from January 1, 1988, through October 31, 2012. Included studies reported on women who met the modified Duke criteria for the diagnosis of IE and were pregnant or postpartum. We included 72 studies that described 90 cases of peripartum IE, mostly affecting native valves (92%). Risk factors associated with IE included intravenous drug use (14%), congenital heart disease (12%), and rheumatic heart disease (12%). The most common pathogens were streptococcal (43%) and staphylococcal (26%) species. Septic pulmonary, central, and other systemic emboli were common complications. Of the 51 pregnancies, there were 41 (80%) deliveries with survival to discharge, 7 (14%) fetal deaths, 1 (2%) medical termination of pregnancy, and 2 (4%) with unknown status. Maternal mortality was 11%. Infective endocarditis is a rare, life-threatening infection in pregnancy. Risk factors are changing with a marked decrease in rheumatic heart disease and an increase in intravenous drug use. The cases reported in the literature were commonly due to streptococcal organisms, involved the right-sided valves, and were associated with intravenous drug use.

    ABSTRACT: Objective To compare 1-year results after aortic valve-sparing (AVS) or valve-replacing (AVR) aortic root replacement from a prospective, international registry of 316 patients with Marfan syndrome (MFS). Methods Patients underwent AVS (n=239, 76%) or AVR (n=77, 24%) aortic root replacement at 19 participating centers between 2005 and 2010. One-year follow-up was completed for 312 patients (99%), with imaging available for 293 patients (94%). Time-to-events were compared between groups using Kaplan-Meier curves and Cox Proportional Hazards models. Results Two patients (0.6%)—1 in each group—died within 30 days. There were no significant differences in early major adverse valve-related events (MAVRE) (P=0.6). Two AVS patients required early reoperation for coronary artery complications. One-year survival rates were similar in the AVR (97%) and AVS groups (98%); procedure type was not significantly associated with any valve-related events. At 1 year and beyond, aortic regurgitation of at least moderate severity (≥2+) was present in 16 patients in the AVS group (7%) but in no patients in the AVR group (P=0.02). One AVS patient required late AVR. Conclusions Valve-sparing aortic root replacement was not associated with higher 30-day mortality or morbidity rates than AVR root replacement. At 1 year, there were no differences in survival, valve-related morbidity, or MAVRE between the AVS and AVR groups. Of concern, 7% of AVS patients developed ≥2+ aortic regurgitation, emphasizing the importance of 5- to 10-year follow-up to learn the long-term durability of AVS versus AVR root replacement in patients with MFS.

    ABSTRACT: Bioprosthetic valve thrombosis (BPVT) is a rare but potentially life-threatening complication. Current guidelines favour surgery or thrombolysis as initial treatment. We set forth to characterize timing, diagnostic criteria and treatment strategies in BPVT. A free-text search tool was used to identify patients diagnosed with BPVT at Mayo Clinic between 1997 and 2013. We compared patients treated initially with vitamin K antagonists (VKA group; N = 15) versus surgery/thrombolysis (non-VKA group; N = 17). Peak incidence of BPVT was 13-24 months after implantation in both groups. VKA and surgery/thrombolysis decreased prosthetic mean gradients to a similar extent (VKA group: 13 ± 5 to 6 ± 2 mmHg in mitral position, 9 ± 3 to 5 ± 1 mmHg in tricuspid position and 39 ± 3 to 24 ± 7 mmHg in aortic/pulmonary position; non-VKA group: 16 ± 12 to 5 ± 1 mmHg in mitral, 10 ± 5 to 4 ± 1 mmHg in tricuspid and 57 ± 9 to 18 ± 6 mmHg in aortic position; P = 0.59 for group effect). NYHA class improved in 11 of 15 patients in the VKA group and 10 of 17 patients in the non-VKA group (P = 0.39). There were no deaths, strokes or recognized embolic events; 1 patient in each group experienced gastrointestinal bleeding requiring transfusion. Index transthoracic echocardiogram formally identified BPVT in a minority of patients. BPVT may occur late after surgical implantation. VKA therapy resulted in haemodynamic and clinical improvement with minimal risk, and should be considered the first-line therapy in haemodynamically stable patients. Echocardiographic criteria for improving BPVT diagnosis are proposed.

    ABSTRACT: Surgical correction of complex aortic coarctation can be associated with significant risks. Extraanatomic bypass may represent a safer alternative. Between January 1985 and December 2012, 80 consecutive patients with complex coarctation underwent ascending-to-descending aortic bypass through a median sternotomy. Patients were a median age of 42 years (range, 15 to 75 years), and 51 (64%) were males. Recurrent coarctation was present in 52 patients (65%), with 6 (8%) having undergone balloon dilatation. Uncontrolled hypertension was present in 63 patients (79%). The most common concomitant pathology was aortic valve stenosis in 21 patients (26%), subaortic stenosis in 10 (13%), and Shone complex in 4 (5%). There were no early deaths. The most common concomitant procedures were aortic valve replacement, coronary artery bypass grafting, and resection of subaortic stenosis. The mean aortic cross-clamp and cardiopulmonary bypass times were 33 ± 40 and 106 ± 54 minutes, respectively. Morbidity included atrial fibrillation in 17 patients (21%) and reexploration for bleeding in 6 (8%). There was no paraplegia or stroke. Upper extremity blood pressure significantly improved (p < 0.001). Mean systolic blood pressure decreased from 153 ± 26 mm Hg preoperatively to 123 ± 15 mm Hg postoperatively. Mean follow-up was 7 ± 6 years (maximum, 22 years). Late deaths occurred in 5 patients (6%) and were not graft-related. Three patients (4%) required reoperation for repair of periprosthetic regurgitation in 2 and mitral valve replacement in 1. The ascending-to-descending aortic bypass can be performed with low morbidity and mortality. It is an effective solution to complex aortic coarctation and represents a safe single-stage approach for patients with concomitant cardiac pathology.

    ABSTRACT: Thoracic aortic aneurysms can be triggered by genetic disorders such as Marfan syndrome (MFS) and related aortic diseases as well as by inflammatory disorders such as giant cell arteritis or atherosclerosis. In all these conditions, cardiovascular risk factors, such as systemic arterial hypertension, may contribute to faster rate of aneurysm progression. Optimal medical management to prevent progressive aortic dilatation and aortic dissection is unknown. β-blockers have been the mainstay of medical treatment for many years despite limited evidence of beneficial effects. Recently, losartan, an angiotensin II type I receptor antagonist (ARB), has shown promising results in a mouse model of MFS and subsequently in humans with MFS and hence is increasingly used. Several ongoing trials comparing losartan to β-blockers and/or placebo will better define the role of ARBs in the near future. In addition, other medications, such as statins and tetracyclines have demonstrated potential benefit in experimental aortic aneurysm studies. Given the advances in our understanding of molecular mechanisms triggering aortic dilatation and dissection, individualized management tailored to the underlying genetic defect may be on the horizon of individualized medicine. We anticipate that ongoing research will address the question whether such genotype/pathogenesis-driven treatments can replace current phenotype/syndrome-driven strategies and whether other forms of aortopathies should be treated similarly. In this work, we review currently used and promising medical treatment options for patients with heritable aortic aneurysmal disorders.

    ABSTRACT: Aortopathy associated with bicuspid aortic valve commonly involves the ascending aorta above the sinotubular ridge, but it may also affect sinus portions of the aorta. In some persons, the enlarged portion of the aortic root is limited to the noncoronary sinus. In such patients, we have spared the remaining portions of the aortic root by replacing the ascending aorta with a polyethylene terephthalate fiber (Dacron) graft and a tongue-shaped extension of the graft, thereby replacing the noncoronary sinus. In the present study, we evaluated late outcomes of this procedure, with specific attention to the fate of aortic tissue in the remaining sinuses. We reviewed the medical records of 1,756 patients with repair of ascending aortic aneurysms at Mayo Clinic from 1993 through 2012. Among the patients, 631 (35.9%) had bicuspid aortic valve, and in 79 (4.5%) of the patients, the noncoronary sinus was replaced along with the ascending aorta. Associated aortic valve operations were performed in 70 patients; 15 had repair and 55 had aortic valve replacement. No early death occurred, but 3 patients died late after operation (5-year survival, 99%). There were 3 late reoperations, all because of native or prosthetic valve problems. Importantly, no instances occurred of aneurysm formation or aortic dissection related to the remaining aorta in the left and right aortic sinuses. In patients with bicuspid aortic valve and aortic root enlargement related mainly to enlargement of the noncoronary sinus, limited replacement of the noncoronary sinus and ascending aorta is a safe and simple procedure that is durable in midterm follow-up.

    ABSTRACT: Isolated mechanical tricuspid valve replacement (mTVR) is uncommon, early mortality is reported to be high, and little is known regarding the long-term outcome. We sought to evaluate the long-term outcome of mTVR. From 1980 to 2007, isolated mTVR was performed in 64 patients (33 men) at our institution; the median age was 45.5 years (6-71 years). There were 2192 tricuspid valve (TV) repairs and 137 isolated bioprosthetic TV replacements during the same time interval. Valve dysfunction was caused by congenital TV abnormality in 45 patients (70%), carcinoid heart disease in 13 (20%), traumatic TV regurgitation in 3 (5%), and other reason in 3 (5%). Twenty-three patients (36%) had at least 1 previous cardiac procedure (TV repair in 8 and bioprosthetic TV replacement in 7). Mechanical prostheses used included Starr-Edwards (before 1993) in 36 patients (56%) and bileaflet prostheses in 28 (44%). Concomitant procedures included atrial septal defect closure in 28 (44%), arrhythmia surgery in 11 (17%), and pulmonary valvectomy for carcinoid disease in 10 patients (16%). Early mortality occurred in 5 patients (7.8%). Early morbidity included a permanent pacemaker in 9 (14%) and reexploration for bleeding in 2 patients (3%). Mean follow-up was 6 years (maximum 22.4 years). Five- and 10-year survival was 65% and 58%, respectively. There was no valve-related mortality. Late morbidity included valve thrombosis in 5 patients (8%); 3 were managed nonoperatively and 2 underwent TV rereplacement. Isolated mTVR still leads to increased early mortality. A mechanical valve can be considered in select situations when anticoagulation is necessary and in the presence of good right ventricular function.

    ABSTRACT: Tricuspid valve (TV) regurgitation in congenital heart disease includes a heterogeneous group of lesions, and few series have documented the outcomes. We reviewed the records of 553 patients with congenital heart disease who had undergone TV surgery for tricuspid regurgitation from January 1993 to December 2010. Patients with Ebstein malformation were excluded. Their mean age was 32 ± 21 years, and 300 were female (54%). The most common diagnoses were conotruncal anomaly in 216 patients (39%), previous ventricular septal defect closure in 83 (15%), atrioventricular septal defect in 77 (14%), and pulmonary atresia with an intact ventricular septum in 11 (2%). Preoperative right-sided heart failure was present in 124 patients (22%), and 55 patients (10%) had pulmonary hypertension. TV repair was performed in 442 (80%) and TV replacement in 111 (20%) patients. Repeat sternotomy was performed in 415 patients (75%). Previous TV repair was present in 44 patients (8%); of these, 17 (38.6%) underwent repeat TV repair. The overall early mortality was 3.1% (17 patients) and was 2.5% for TV repair and 5.4% for TV replacement (P = .001). The mean follow-up period was 4.5 ± 4.1 years (maximum, 18). The overall survival at 1, 5, and 10 years was 97%, 93%, and 85%, respectively. Survival was better for patients with repair than with replacement. TV repair was an independent predictor of better survival (P = .001). Important tricuspid regurgitation can occur with a variety of congenital diagnoses. Early mortality is low and late survival is superior with tricuspid repair than with valve replacement. Surgical treatment of tricuspid regurgitation in congenital heart disease should be performed before the onset of heart failure.

    ABSTRACT: Carcinoid is a rare neuroendocrine tumor that typically originates in the gastrointestinal tract and can result in a constellation of symptoms, mediated by vasoactive substances, referred to as carcinoid syndrome. Carcinoid valve and heart disease is characterized by the plaque-like, endocardial fibrous tissue deposits, primarily affecting the right heart endocardium and valves, which result as a consequence of the disease process. Potential mechanisms for the carcinoid valve disease include the complex role of excess serotonin and its interaction with serotonin receptors and transporters. Carcinoid valve and heart disease is a frequent occurrence in patients with carcinoid syndrome and is accountable for substantial morbidity and mortality. Cardiac surgery remains the most effective treatment option for carcinoid valve disease and a multidisciplinary approach at an experienced center is recommended for patients with metastatic carcinoid and carcinoid heart disease.

    ABSTRACT: Cardiac malformations occur in approximately 1% of live births. Advances in surgery, interventional cardiology, and medical care have translated into increasing numbers of adult patients with congenital heart disease. These patients, even after intervention, have cardiac sequelae that require specialized care by cardiologists and cardiac surgeons with expertise in the management of congenital cardiac disease. We review 8 of the most common lesions encountered after intervention in an adult congenital cardiac practice and discuss longitudinal follow-up, with a focus on appropriate testing, common hemodynamic and electrophysiological issues, and indications for reintervention.

    ABSTRACT: Our objective was to review the long-term outcome of patients undergoing surgical repair of aortic coarctation. Surgical repair of aortic coarctation has been performed at Mayo Clinic for over 60 years. Between 1946 and 2005, 819 patients with isolated coarctation of the aorta underwent primary operative repair. Medical records were reviewed and questionnaires mailed to patients. Mean age at repair was 17.2±13.6 years. The majority (83%) had preoperative hypertension. Operations included simple and extended end-to-end anastomosis (n=632), patch angioplasty (n=72), interposition graft (n=49), bypass graft (n=30) and subclavian flap or other (n=35). Overall early mortality (<30 days) was 2.4%. In the last 30 years (n=225), there were no operative deaths. Mean follow-up was 17.4±13.9 years with a maximum of 59.3 years. Actuarial survival was 93.3%, 86.4%, and 73.5% at 10, 20 and 30 years, respectively. When compared to an age and gender matched population, long-term survival was decreased (P<0.001). Older age at repair (>20 years) and preoperative hypertension were associated with decreased survival (P<0.001). Patients less than 9 years at the age of repair had significantly less hypertension at 5-15 years of follow-up (P<0.001). Freedom from reintervention on the descending aorta was 96.7%, 92.2%, and 89.4% at 10, 20 and 30 years, respectively. Younger age at time of repair (P<0.001) and an end-to-end anastomosis technique (P<0.001) were independently associated with lower reintervention rates on the descending aorta. Primary repair of isolated coarctation of the aorta can be performed with low mortality. However, long-term survival is reduced compared to an age and gender matched population and many patients will require further reoperation. These findings emphasize that patients with aortic coarctation need early recognition and intervention, as well as life-long informed follow-up.
