Jin Young Song, Yong Soo Yoon
Clin Exp Pediatr. 2000;43(2):229-235.   Published online February 15, 2000
Purpose : Total anomalous pulmonary venous return is a rare congenital heart disease, which is fatal if untreated, especially, if the obstruction in pulmonary venous return is obstructed.

Dong Hyun Choo, Dong Kyoon Kim, Jung Yeon Choi, Yong Soo Yoon, Chang Yee Hong
Clin Exp Pediatr. 1984;27(8):814-819.   Published online August 31, 1984
Isolated congenital tricuspid insufficiency is a rare anomaly and may be caused by abnormal chordae tendinae, papillary muscle, or valve leaflets. The cause of these lesions is generally ascribed to incomplete undermining of primitive endocardial cushion by sinusoidal space, which differentiate the cushion into the various valvular structures. Carvallo’s sign, most characteristic clinical sign in tricuspid insufficiency, is augumentation of systolic...

Pulmonary artery aneurysms are extremely rate and are seldom diagnosed during life. In true aneurysms, dilatation tends to be confined to the main trunk of the artery and degenerative changes in the wall are found. In 1971, Williams et al reported the first successful excision and replacement of the main pulmonary artery, including the bifurcation, with a dacron graft. Since...
