Intracardiac hydatid cyst and sudden death in a child.

Left ventricular hydatid cyst was diagnosed in a 4-year-old boy by echocardiography. The patient did not respond to oral mebendazole therapy and had a sudden death, probably due to rupture of the cyst. The occurrence of cardiac hydatid cyst and its life threatening complications are rare and have not been reported in children.

Adverse effects of oral amiodarone therapy.

Oral amiodarone was administered to 38 patients (25 males, 13 females) with mean age of 43.6 years. Ventricular and supraventricular arrhythmias were present in 30 and 8 patients respectively.

Cor-triatriatum with atrial septal defect and bicuspid aortic valve diagnosed by cross-sectional echocardiography.

We report a rare case with a combination of cor-triatriatum, large secundum atrial septal defect and bicuspid aortic valve. The diagnosis was made by cross-sectional echocardiography. A defect was present between proximal (accessory) left atrial chamber and right atrium decompressing the accessory left atrial chamber.
