[Show abstract][Hide abstract] ABSTRACT: The standard surgical approach for closed heart procedures in small infants and children is to use a posterolateral thoracotomy incision, which results in the division of the latissimus dorsi and serratus anterior muscles. The aim of our study was to determine the frequency and type of musculoskeletal deformities in children undergoing surgery with this approach for congenital cardiac disease. We included 49 children, 28 boys and 21 girls, in the study. Their mean age was 10.2 +/- 4.8 years, the mean age at the time of surgery was 3.8 +/- 4.0 years, and they were evaluated at an average of 6 years after the thoracotomy. Of the patients, 94% had various musculoskeletal deformities. Scoliosis was observed in 15 patients (31%) but only in two patients did the curves exceed 25 degrees. Of these patients, three-fifths had aortic coarctation. Elevation of the shoulder was seen in 61%, winged scapula in 77%; while 14% had asymmetry of the thoracic wall due to the atrophy of the serratus anterior muscle. Deformity of the thoracic cage was observed in 18%; and 63% had asymmetry of the nipples. Thus, we found that musculoskeletal deformities are frequent after thoracotomies in children with congenital cardiac disease. Patients who have undergone such procedures for cardiac or noncardiac surgery should be followed until their skeletal maturation is complete. Techniques sparing the serratus anterior and latissimus dorsi muscles should be preferred. These adverse effects of thoracotomy may be another reason for using interventional procedures in these cases.

[Show abstract][Hide abstract] ABSTRACT: We report 12 patients with ventricular noncompaction who were echocardiographically identified at our institution since 1991. The mean age at presentation was 3.5 years. Five patients had isolated noncompaction. Three of them had subnormal left ventricular systolic function at presentation. Noncompaction was associated with complex congenital heart defect in 3 patients. Four patients had simple congenital heart defects: pulmonary stenosis, coarctation of aorta with aberrant origin of right subclavian artery, ventricular septal defect, and partial anomalous pulmonary venous return. The observed rhythm abnormalities were Wolff-Parkinson-White syndrome and paroxysmal supraventricular tachycardia, bigemini ventricular extrasystoles, and left bundle branch block. A transvenous pacemaker was implanted in a patient because of complete heart block. Noncompaction of the ventricular myocardium is rare. Our patients clearly represent the clinical and morphological spectrum of this disorder. Distinct morphological features can be diagnosed on 2-dimensional echocardiography.

[Show abstract][Hide abstract] ABSTRACT: Doppler indexes have been used successfully to determine the severity of aortic regurgitation (AR) in adults but have not been evaluated in children. To determine the accuracy of pulsed, color, and continuous-wave (CW) Doppler echocardiographic indexes in assessing the degree of AR in children, the correlation between the non-invasive measurements and angiographic grading of the regurgitant flow (1+ to 4+) was examined in 14 children (mean age 11 +/- 3 years) with chronic AR. Forward and reverse flows in the aortic arch were evaluated from the suprasternal notch using pulsed Doppler. Aortic time-velocity integrals (TVI) were measured during systole (forward flow) and diastole (reverse flow), and the ratio of reverse to forward TVI (%) was calculated. Doppler color flow mapping was used to detect and assess the severity of AR (which appears as mosaic turbulent signals extending in the left ventricular outflow tract during diastole) by using four color Doppler grades of severity. The envelope of the flow velocity pattern in diastole was recorded from the CW Doppler signal of AR with the transducer in the lower sternal border to determine the peak flow velocity and deceleration slope (alpha) indexes. The ratio of reverse to forward aortic TVI and color flow mapping grading showed strong correlation with angiographic grade (r=0.92 and r=0.86, respectively) but AR slope (alpha) and peak flow velocity did not correlate well with the angiographic grade (r=-0.039 and r=0.74, respectively). We concluded that the severity of AR in children as determined by angiographic grading can be estimated with reasonable accuracy by noninvasive technique based on color and pulsed wave Doppler. Use of these indexes may obviate the need for angiography to detect the severity of AR in children.

[Show abstract][Hide abstract] ABSTRACT: Origin of the left main coronary artery from the pulmonary trunk is an extremely rare, fatal, but potentially treatable anomaly. Left ventricular perfusion with desaturated blood with low pressure from the pulmonary artery results in early death. Associated pulmonary hypertension can help to prevent ischemia. We present a four-month-old boy with this anomaly associated with patent ductus arteriosus and pulmonary hypertension.

[Show abstract][Hide abstract] ABSTRACT: Valvar aortic stenosis is a common congenital heart defect for which surgical procedures can be done with low risk except in infants whose conditions are seriously compromised. The purpose of this report was to present our experience with the results of surgical aortic valvotomy for congenital valvar aortic stenosis performed at our hospital. The study group consisted of 24 patients, 3 females and 21 males, with ages ranging from 1 to 15.5 years (mean age 8.5 years), who underwent aortic valvotomy for valvar aortic stenosis. The case records of all the patients were retrospectively reviewed. They were followed for 1-10.5 years (mean 5.02+/-2.38 years) after relief of aortic stenosis, and were scheduled for reevaluation. Sixteen of the 24 patients were recatheterized and 15 (93.7%) were found to have aortic regurgitation on angiography. Peak systolic pressure gradients (mean+/-SD) were 65.9+/-19.5 mmHg before and 36.7+/-14.8 mmHg (p<0.05) after the operatilon. Of the 24 patients, 45.8% had a new postoperative diastolic murmur. Twenty patients (83.3%) had residual stenosis and three (12.5%) had recurrent stenosis. Two patients (8.3%) had undergone reoperation six to seven years after the initial aortic valvotomy, and most of the others will require reoperation in the future. No sudden deaths occurred in this series. Timely relief of obstruction prevents sudden death and produces symptomatic improvement in valvar aortic stenosis, but aortic valvotomy is only a palliative measure.

[Show abstract][Hide abstract] ABSTRACT: This study was designed to evaluate possible interactions between digital cellular telephones and implanted pacemakers in children. The study comprised 95 patients (53 males and 42 females) with a mean age of 11.5 +/- 4.6 years (range 1-22 years). The average time from pacemaker implantation was 2.5 years (range 1 month-12 years). Fourteen (15%) devices were dual chamber and the remaining were single chamber pacemakers. The following companies manufactured the pacemakers tested: Medtronic (n = 42), Telectronics (n = 9), Vitatron (n = 16), Pacesetter (n = 19), CPI (n = 8), and Biotronik (n = 1). All the patients were tested in the supine position during continuous ECG monitoring. After completion of the routine pacemaker check, the effects of the European Global system for mobile communication (GSM) was tested using two cellular telephone models (Ericsson GA 628 and Siemens S 25, 2-W power). For this purpose, atrial and ventricular sensitivity settings were programmed to the most sensitive values, and the tests were carried out in the unipolar and bipolar sensing modes. The evaluation was performed during ringing, switching on/off, and conversation phase with the cellular telephone positioned over the pulse generator and around the pacemaker pocket. A malfunction of the pacemaker was not observed in any patient. Only 1 (1%) of 95 patients showed a brief oversensing problem during calls with the cellular telephone. In this case, an AAIR pacemaker was implanted transvenously in a subcutaneous pocket and the sensing defect occurred only with the unipolar sensing mode and was not reproducible. Once the source of interference was removed, no sensing defect was detected and the patient remained asymptomatic. No symptoms were experienced in this study. The authors believe that pacemaker dependent patients with nonprotected pulse generators manufactured at the beginning of 1990s may be tested by their physicians for possible interferences before they use a digital cellular telephone.
[Show abstract][Hide abstract] ABSTRACT: Visceroatrial situs, ventricular morphology, and atrioventricular and ventriculoarterial alignments can reliably be assessed with fetal echocardiography. We herein describe, to our knowledge, the first reported fetal echocardiographic diagnosis of a fetus with visceroatrial situs solitus, atrioventricular alignment discordance, double outlet right ventricle, and superoinferior ventricles of a 22-year-old gravida III para II woman with a previous history of intrauterine fetal death. She had been evaluated at another center and was referred to our unit because of the suspicion about her diagnosis and underwent fetal ultrasonographic evaluation at 39 weeks gestation. Neonatal echocardiographic evaluation and autopsy findings confirmed the diagnosis. Accordingly there was (solitus, L-loop ventricle, and anterior aorta) double outlet right ventricle, superoinferior ventricles with diminutive right ventricle, noncommitted trabecular ventricular septal defect, and pulmonary hypertension.

[Show abstract][Hide abstract] ABSTRACT: Isolated noncompaction of the ventricular myocardium is a rare congenital cardiomyopathy resulting from an arrest in normal endomyocardial embryogenesis. The diagnosis can be made echocardiographically, and the entity may be associated with problems of cardiac rhythm. We describe two illustrative cases, with Wolf-Parkinson-White syndrome in one, and left bundle branch block in the other. We emphasize that children with problems of rhythm and findings suggestive for left ventricular cardiomyopathy, either hypertrophic or dilated; should be investigated to exclude isolated noncompaction of the ventricular myocardium.
