CoreValve bioprosthesis dysfunction treated with a Sapien 3 valve‐in‐valve transcatheter aortic valve replacement and BASILICA technique

Structural deterioration of transcatheter heart valve (THV) has been previously described. With the expansion of transcatheter aortic valve replacement (TAVR) indications toward treating lower risk patients with longer life expectancy, there will be increased necessity of managing the patients with THV dysfunction including those at risk for coronary obstruction or sinus sequestration. Coronary access also remains a challenge in such cases with THV dysfunction undergoing valve-in-transcatheter heart valve (ViTHV) TAVR. A unique and first reported case of THV deterioration treated with Sapien 3 ViTHV-TAVR inside a 31 mm CoreValve bioprosthesis along with left coronary leaflet laceration using the BASILICA technique has been presented.
