Congenital Aneurysmal Tunnel of the Trabecular Muscular Interventricular Septum or a Partially Closed Ventricular Septal Defect? A Case Report with Review of Literature
Abstract
Isolated congenital aneurysm-like deformity of the muscular interventricular septum is rare and may be associated with other congenital heart defects, ventricular dysfunction, conduction disturbances, and chromosomal abnormalities. It may be a partial or near-total defect. We report a tunnel-like congenital anomaly of the mid-muscular ventricular septum without other congenital anomalies or conduction disturbance in a 17-year-old asymptomatic girl. The partial ventricular septal defect was lined on the outer side by the right ventricular endocardium and showed partial obliteration during systole.
