Congenital right ventricular diverticulum associated with a ventricular septal defect: a rare echocardiographic finding.

摘要

A neonate presented on the first day of life with tachypnea and poor feeding. The infant's initial echocardiogram demonstrated outpouching of the lateral wall of the right ventricle (RV) associated with a large ventricular septal defect (VSD). At 9 days of age he was diagnosed with osteogenesis imperfecta (OI). Despite treatment with digoxin, diuretics, and captopril he required hospitalization twice during his first 2 months of life for congestive heart failure (CHF). The VSD was closed at three and one-half months of age without resection of the diverticulum and CHF symptoms resolved. At 26 months of age he is doing well despite the residual RV diverticulum. Congenital cardiac diverticula are rare forms of cardiac malformations and their echo-Doppler features are herein discussed.
