Role of Transesophageal Echocardiography in Perventricular Closure of Muscular Ventricular Septal Defect

Muscular ventricular septal defect (mVSD) transcatheter occ l usion technique is an established and preferred treatment modality and has become an alternative to surgery under extracorporeal circulation. But in small infants with large size of delivery assembly visvis small size of vessel caliber, it becomes not only technically challenging, but also pos sesses serious procedurerelated complications. Perventricular device closure of such VSD on beating heart is an alternative. In this study, we aimed to present the role of intraoperative transesophageal echocardiography (TEE) in successful per ventricular closure of mVSD in a small infant.
