Key result
Percutaneous transcatheter closure of an iatrogenic membranous VSD using the Amplatzer Duct Occluder II Device from an entirely retrograde approach was successfully performed in a single patient.
Case Report (n=1)
Demonstrates the feasibility of using the Amplatzer Duct Occluder II Device via a retrograde approach for transcatheter closure of iatrogenic membranous VSDs.
Single-case success supports technical feasibility; leaves open safety, efficacy, and durability before wider use.
Iatrogenic membranous ventricular septal defects (VSD) are rare complications of cardiothoracic surgery, most commonly seen as a complication of aortic valve replacements. An iatrogenic VSD can lead to right sided heart failure, systemic hypoxia, and arrhythmias, and closure is often necessary. Given the increased mortality associated with repeat surgical procedures, percutaneous transcatheter closure of these iatrogenic VSDs has increasingly become the preferred choice of therapy. We describe the first case of iatrogenic membranous VSD in the setting of mitral valve replacement and tricuspid valve repair, using the newly approved Amplatzer Duct Occluder II Device from an entirely retrograde approach.

Retzer et al. (2014) conducted a case report in Iatrogenic membranous ventricular septal defect (n=1). Percutaneous transcatheter closure using the Amplatzer Duct Occluder II Device was evaluated. Percutaneous transcatheter closure of an iatrogenic membranous VSD using the Amplatzer Duct Occluder II Device from an entirely retrograde approach was successfully performed in a single patient.
