Successful minimal approach transcatheter aortic valve replacement in an allograft heart recipient 19 years post transplantation for severe aortic stenosis: A case report.

Background: Aortic stenosis is one of the rare valvular complications in a transplanted heart. Over the past 8 years, transcatheter approach for aortic valve replacement (TAVR) has been slowly evolving to be the preferred approach in these patient population when compared to the surgical approach. We report a second case in the United States with successful transfemoral minimal approach with minimal sedation for TAVR in a heart transplant recipient 19 years post transplantation for severe symptomatic calcified aortic stenosis.

Transcatheter aortic valve replacement in membranous interventricular septum aneurysm with left ventricular outflow tract extension.

We report a challenging case of a 81-year-old male with history of severe calcific aortic valve stenosis and aneurysmal membranous interventricular septum. The presence of anomalies in the sub-annular area can lead to valve malpositioning and its consequences. transcatheter aortic valve implantation (TAVR) in patients with aneurysm of the perimembranous interventricular septum extending into the left ventricular outflow tract has not been previously reported.
