Double chamber right ventricle with perimembranous VSD with sinus of valsalva aneurysm-An unhitherto assosciation

Background Double chambered right ventricle with perimembranous ventricular septal defect is rare. Aims and material methods We report a case of double chambered right ventricle, perimembranous ventricular septal defect with nonruptured sinus of valsalva aneurysm in a 17 year old acyanotic male. Results, Discussion On transthoracic echocardiography subaortic ventricular septal defect potentially restricted by prolapse of right coronary sinus was found. Computed tomography angiography revealed perimembranous ventricular septal defect, unruptured right sinus of valsalva aneurysm, prolapsing into right ventricle through membranous septal defect. Thick muscular band was dividing right ventricle into two chambers-suggestive of double chamber right ventricle. Conclusion We report a case of double chambered right ventricle with perimembranous ventricular septal defect and nonruptured sinus of valsalva aneurysm, this combination is not reported in literature prior.
