Five high-risk patients undergoing the Fontan operation required large fenestration (1 cm) because of high central venous pressure and low cardiac output. Because of major arterial desaturation, obligatory Glenn shunts were performed. Three patients had pulmonary atresia, 1 had tricuspid atresia 1-B, and the fifth had single ventricle with subaortic(More)
Wide variation in morphology of double-outlet left ventricle allows numerous surgical alternatives that require sorting out to develop a more organized approach. There is a high association between tricuspid abnormalities and right ventricular hypoplasia with double-outlet left ventricle that calls for either Fontan-type procedure or biventricular repair.(More)
A 670 g premature infant is described in whom an intracardiac thrombus was documented. This thrombus formation probably resulted as a complication of an indwelling right atrial catheter. Thrombolytic therapy with urokinase was instituted, resulting in total and rapid dissolution. No hemorrhagic complications resulted. We believe that this particular(More)
Over a 12-year period, 40 patients underwent repair of partial anomalous pulmonary veins (PAPV) draining to the superior vena cava (SVC) proximal to the sinus node. Mean age was 6 +/- 2 years. In all patients, the SVC was cannulated superior to the PAPV, which were baffled with pericardium to left atrium. Six patients had associated defects repaired. In 18(More)
Failure to recognize the presence of accessory mitral tissue causing subaortic stenosis can lead to not only the performance of inappropriate operations, but the persistence and recurrence of obstruction or even death. Over a 12-month period, we treated 2 children with severe subaortic stenosis caused by accessory mitral tissue. In 1 patient, who was 4(More)
A 9-month-old infant experienced severe chloramphenicol toxicity associated with high serum levels (313 μg/ml). Cardiovascular collapse with cardiomyopathic changes and impaired left ventricular function was documented by echocardiography. Serial echocardiographic evaluation showed resolution of the cardiomyopathic findings as the chloramphenicol levels(More)
Over a 13-year period, 20 infants and children underwent transsternal approach for repair of coarctation and associated cardiac defects. Fifteen patients (75%) were operated on in the last 6 years. Thirteen patients (group 1) had intracardiac shunts and 7 (group 2), intracardiac obstruction or valvular insufficiency. Group 1 had a mean age of 0.8 +/- 1.9(More)
A child with Marfan's syndrome had cardiac failure during infancy. Aortic sinus aneurysms, mitral prolapse with severe regurgitation, and atrial septal defect were present. After myocardial infarction at age 4 years, the mitral prolapse became less and the regurgitation disappeared. After recovery of left ventricular function, mitral regurgitation(More)
Two-dimensional echocardiography is a useful noninvasive tool for diagnosing intrapericardial tumors as a cause of respiratory distress or abnormal cardiomediastinal shadow on chest x-ray. Early recognition of these tumors within the pericardium is important since surgical removal is often curative. Cardiac cineangiography is unnecessary to delineate(More)
