A case of anomalous origin of the left coronary artery from the pulmonary artery is reported. The diagnosis was made on the basis of characteristic Tc 99m lung scan findings and was confirmed by subsequent angiocardiography and surgery.
Two cases of congenital diverticulum of the left atrial appendage are described. The first patient was a 3-year-old girl who had a cerebral embolism. The second patient was a 3(1/2)-year-old girl with signs of pericarditis. Treatment consisted of excising the diverticula. The limited literature on diverticulum of the left atrium as a congenital abnormality is also briefly reviewed.
This report concerns a 3(1/2)-year-old boy who had a supravalvular stenosing ring of the left atrium that produced left ventricular inflow obstruction. Echocardiographic and angiocardiographic data are presented, along with a review of the literature and possible theories as to the origin of this lesion.
