From The Valve Wire

The TAVR-explant problem is now a number we can quote at heart team meetings. [NOTABLE] A narrative review of four studies and 35,677 patients pegs operative mortality of redo SAVR after TAVR at 12-17% versus 1.1-9% after prior SAVR , with propensity-matched odds ratios as high as 12.5 and observed-to-expected ratios exceeding 1.0 even in low-risk patients.

TAVR-SAVR volume is growing at up to 144.6% annually and may eclipse SAVR-SAVR by 2029.

Editor’s take pending for this article; this is the section commentary excerpt.

Source Abstract

New-onset left bundle branch block (LBBB) following transcatheter aortic valve implantation (TAVI) is a common conduction disorder, sometimes transient. Conversely, the development of sustained ventricular tachycardia (VT) after TAVI is rare and its management is challenging. We report the case of a female patient with aortic stenosis treated with transcatheter self-expandable aortic valve implantation, who developed new-onset LBBB post-procedure. Several days later, the patient experienced hemodynamically tolerated slow VT with a right bundle branch morphology. She underwent an electrophysiological study, but slow VT was only transiently interrupted. Due to the persistence of slow VT, the patient was discharged with an external loop recorder, which revealed spontaneous resolution of VT and regression of LBBB after a few days.
