Left Main Protection During Transcatheter Aortic Valve Replacement With a Balloon-Expandable Valve.

ABSTRACT:

Background

Coronary obstruction during transcatheter aortic valve replacement (TAVR) is a rare, yet life-threatening, complication. The routine use of left main (LM) protection with or without stent placement in high-risk patients remains controversial. The aim of this study was to evaluate the outcomes of LM protection during TAVR and identify anatomic factors associated with need for stent placement.

Methods

We retrospectively reviewed all TAVR cases (native and valve-in-valve) performed in our institution between 2014 and 2019 and identified patients who underwent LM protection with a coronary wire, balloon, and/or stent during the procedure. We compared the pre-TAVR computed tomography aortic root characteristics, procedural data, short-, and long-term outcomes among the
