Youn Jeong Shin, Sung Hee Jang, Jung Yun Choi, Eun Sook Han
Clin Exp Pediatr. 2002;45(2):267-272.   Published online February 15, 2002
Typical hypoplastic left heart syndrome(HLHS) is a distinct pathologic entity with aortic atresia, mitral atresia, very hypoplastic or absent left ventricle and thread like ascending aorta. Occasionally, the lesser degree of hypoplasia is found and is called hypoplastic left heart complex(HLHC) by some authors. This HLHC is often associated with critical aortic stenosis. Fetal echocardiography has enabled us to observe...

A Case of Protein-losing Enteropathy in Congestive Heart Failure : Resolution with Prednisolone
Jong-Woon Choi
Clin Exp Pediatr. 2001;44(5):587-591.   Published online May 15, 2001
Protein-losing enteropathy can result from primary or secondary intestinal lymphangiectasia. Secondary intestinal lymphangiectasia develops as a result of lymphatic obstruction or elevated lymphatic pressure. Cardiac lesions such as constrictive pericarditis, post-Fontan procedure state, and chronic congestive heart failure increase lymphatic pressure and may cause intestinal lymphangiectasia and protein-losing enteropathy. An 11-year-old girl who underwent corrective surgery for Tetralogy of Fallot...
