Bailout From Sinus Jailing: In-Series TAVR-in-TAVR to Avoid Coronary Flow Obstruction.

ABSTRACT

Redo transcatheter aortic valve replacement (TAVR) may pose the risk of coronary flow obstruction. We report 2 cases of severe TAVR regurgitation due to different physiopathological mechanisms in which TAVR-in-TAVR could be at high risk for sinus sequestration. Both cases were successfully treated by in-series implantation of a second transcatheter heart valve, thus avoiding sinus sequestration. (Level of Difficulty Intermediate.).
