Key result
VSD closure without RV diverticulum resection resolves CHF symptoms in a neonatal case.
Why the study?
Congenital cardiac diverticula are rare cardiac malformations with limited echocardiographic characterization.
Case Report (n=1)
Surgical closure of a VSD without resection of an associated right ventricular diverticulum can lead to resolution of heart failure symptoms in an infant.
May spare diverticulum resection in select infant VSD cases; hypothesis-generating and requires prospective validation.
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.

Sessa et al. (2006) conducted a case report in Congenital right ventricular diverticulum and ventricular septal defect (n=1). Ventricular septal defect closure without resection of the diverticulum was evaluated on Resolution of congestive heart failure symptoms. Surgical closure of a ventricular septal defect without resection of an associated right ventricular diverticulum resolved congestive heart failure symptoms in a neonate followed to 26 months of age.
