Myocardial infarction and left coronary ostial stenosis in infancy simulating anomalous origin of the left coronary artery. A case report.

A case of a 3-month-old male infant with myocardial infarction due to left coronary ostial stenosis is presented. Clinically it was quite similar to anomalous origin of the left coronary artery. Postmortem examination revealed quite narrow left coronary ostium and myocardial infarction with aneurysm of the left ventricular apex.

Lipoma of the heart in a child. Clinical, echocardiographic, angiographic, and pathological features.

A 7-year-old boy presented with intermittent systolic murmur and syncope. Chest roentgenogram revealed mild cardiomegaly. Electrocardiogram showed right bundle branch block and abnormal T-waves. Right ventricular angiography demonstrated a filling defect at the anterior portion of the right ventricular cavity and histological examination of biopsy specimen revealed lipoma. At operation, the tumor could not be totally resected. Histological examination of surgical specimen showed marked proliferation of mature fat cells between cardiac muscle fibers. Postoperatively he has been remained asymptomatic. Postoperative standard M-mode and two-dimensional echocardiogram demonstrated a mass from right ventricular wall, abnormal motion of the interventricular septum and small left atrial cavity. The patient has been followed by serial echocardiography.

Constrictive pericarditis with atrial septal defect in children.

Two cases of (1-year-old and 13-year-old) of constrictive pericarditis (CP) associated with atrial septal defect (ASD) are presented. The correct diagnosis was made preoperatively in both cases. Both patients underwent surgery (pericardiectomy and ASD closure). One patient died soon after the surgery because of low cardiac output. The other patient was associated with protein-losing enteropathy and it improved dramatically after the operation. Cardiac catheterization is necessary for the diagnosis of this unusual combination. The cause of this unusual combination is obscure.
