Cardiac Imaging of Percutaneous VSD Closure


Video Supplement to “Percutaneous Closure of an Iatrogenic Perimembranous Ventricular Septal Defect After Mechanical Aortic Valve Replacement Using a Novel Venous-Arteriovenous Loop" [April 2019 Clinical Images article by So, et al.]

A 63-year-old woman developed heart failure symptoms 1 year after successful mechanical aortic valve replacement and dual-chamber pacemaker implantation due to postoperative heart block. Transthoracic and transesophageal echo revealed an 8 x 10 mm iatrogenic perimembranous ventricular septal defect (VSD) with left-to-right shunting. This imaging series details the percutaneous closure of perimembranous ventricular septal defect occluder utilizing a novel venous-arteriovenous loop, and emphasizes the importance of concomitant fluoroscopic and echocardiographic guidance in structural heart interventions.
