Repair of posterior left ventricular aneurysm in a six-year-old boy.

Left ventricular aneurysms and diverticula are rarely encountered in the pediatric age group. This paper reports a case of congestive heart failure and mitral regurgitation in a 6-year-old boy with a large posterolateral left ventricular aneurysm. Complete repair was successfully performed by excision of the aneurysm and Dacron patch reconstruction of the left ventricular free wall. The patch extended onto the posterior annulus of the mitral valve, thus restoring the mitral valve to normal geometry and correcting the mitral insufficiency. The surgical literature on congenital cardiac diverticula and acquired aneurysms in children is reviewed and summarized.

Successful excision of an atrial fibroma in a four-month-old male infant.

This report presents an infant who was initially admitted with a pericardial effusion. Subsequent evaluation led to the diagnosis of a primary cardiac tumor. Excision of the tumor which arose from the atrial septum was possible only by removing most of the free right atrial wall and a portion of the septal leaflet of the tricuspid valve. Reconstruction of the tricuspid valve leaflet by reattachment of chordae and a partial annuloplasty was done with the right atrial wall being replaced using pericardial tissue. The histology of the tumor was compatible with a fibroma, a type not previously reported in this location in the pediatric age group. Twenty-one months following operation, the child was restudied and the catheterization revealed mild to moderate tricuspid regurgitation and no recurrence of the tumor. The child is now 4 years of age and remains asymptomatic with normal growth and development and no evidence of fibromatosis.

Familial nonobstructive cardiomyopathy with endocardial fibroelastosis beyond infancy.

A 10-year-old boy with congestive heart failure died in five months in spite of comprehensive medical treatment. Autopsy showed patchy areas of endocardial fibroelastosis of the left ventricle. The sister of this patient had followed a similar course at 13 years of age with death within six months of the onset of congestive failure. Her postmortem examination also showed endocardial fibroelastosis. The clinical presentation of familial endocardial fibroelastosis in the preteen and teenage years is a rare event. Probably the endocardial fibroelastosis was secondary to a familial nonobstructive cardiomyopathy.

Masked abnormal drainage of the inferior vena cava into the left atrium.

A 6 year old boy with a large atrial septal defect, partial anomalous pulmonary venous drainage and unrecognized anomalous insertion of the inferior vena cava into the left atrium had cyanosis after closure of the atrial defect. Repeat study revealed direct drainage of the inferior vena cava into the left atrium with moderate arterial oxygen desaturation. At repeat operation an unusual positioning of the inferior vena cava was seen. After reopening of the atrial defect, the pulmonary venous and systemic venous drainage anomalies were identified. A Dacron patch was inserted so as to divert flow to the proper atrium. Repeat catheterization 3 months after operation revealed a normal heart with no obstruction; arterial oxygen saturation was normal. The child has continued to do well 3 years after operation.
