Abstract

Objective

To determine the safety and efficacy of valve-in-valve transcatheter aortic valve replacement (ViV) versus redo surgical aortic valve replacement (SAVR) for the treatment of previously failed aortic bioprostheses.

Background

Valve-in-valve has emerged as a treatment option for patients with a failed aortic bioprosthesis. Evidence for safety and efficacy remains limited to small studies.

Methods

Medline and Embase were searched to 2017 for studies that directly compared ViV to redo SAVR. A random effects meta-analysis was performed.

Results

Four unadjusted (n = 298) and two propensity-matched (n = 200) observational studies were included. Valve-in-valve patients were 2.85-years older (P = 0.03) and were 23% higher in predicted mortality risk (ratio of means: 1.23, 95% confidence interval (95%CI): 1.02–1.48). There was no difference in peri-operative mortality (4.4% vs. 5.7%, P = 0.83;I2 = 0%) or late mortality, reported at median one year follow-up (incident rate ratio (IRR) 0.93, 95%CI: 0.74–1.16, P = 0.51, I2 = 0%) between ViV and redo SAVR. The incidence of permanent pacemaker implantation (8.3% vs 14.6%; P = 0.05;I2 = 0%) and dialysis (3.2% vs. 10.3%; P = 0.03; I2 = 0%) were lower in ViV. There was a reduction in the incidence of severe patient-prosthesis mismatch (3.3% vs 13.5%; P = 0.03; I2 = 0%) and mild or greater paravalvular leak (5.5% vs 21.1%; P = 0.03; I2 = 37%) in the redo SAVR group compared to ViV.

Conclusions

Despite higher predicted surgical risk of ViV patients, there was no difference in mortality but less permanent pacemaker implantation and dialysis compared to redo SAVR. Choice of treatment must be individualized for both anatomical and patient risk factors; in high risk patients with favorable previous prosthesis size, valve-in-valve may be preferred.
