Incidence, Causes, and Outcomes Associated With Urgent Implantation of a Supplementary Valve During Transcatheter Aortic Valve Replacement.

ABSTRACT:

Importance

Transcatheter aortic valve replacement (TAVR) failure is often managed by an urgent implantation of a supplementary valve during the procedure (2-valve TAVR [2V-TAVR]). Little is known about the factors associated with or sequelae of 2V-TAVR.

Objective

To examine the incidence, causes, and outcomes of 2V-TAVR.

Design, setting, and participants

A retrospective cohort study was performed using data from an international registry of 21 298 TAVR procedures performed from January 1, 2014, through February 28, 2019. Among the 21 298 patients undergoing TAVR, 223 patients (1.0%) undergoing 2V-TAVR were identified. Patient-level data were available for all the patients undergoing 2V-TAVR and for 12 052 patients (56.6%) undergoing 1V-TAVR. After excluding patients w
