Cardiogenic shock following balloon post-dilatation in transcatheter aortic valve implantation: first case report of all three stuck leaflets.

ABSTRACT:

Background

A stuck leaflet and frozen cusp are reported complications following transcatheter aortic valve implantation (TAVI). These complications are rare but can drastically change haemodynamics and be potentially life-threatening; thus, their awareness during TAVI is indispensable. Leaflet malfunction generally presents in one of the three leaflets of a prosthetic valve; however, we encountered a case where all three leaflets were simultaneously stuck.

Case summary

A 94-year-old woman was referred to our cardiology department with severe aortic stenosis. She underwent transfemoral TAVI. After a 20 mm balloon was inflated, a 23 mm Sapien 3 valve was deployed. Since the delivery balloon slipped into the ventricle, the valve top was not fully expanded. Post-dilatation using
