Does mild paravalvular regurgitation increase all-cause mortality in patients undergoing TAVI for severe symptomatic aortic stenosis?
Mild paravalvular regurgitation after TAVI is associated with a significant 1.4-fold increased risk of mortality at 5 years compared with none or trace PVR.
The impact of mild paravalvular regurgitation (PVR) after transcatheter aortic valve implantation (TAVI) remains controversial. We evaluated the impact of mild PVR after TAVI on long-term clinical outcomes. We included patients who underwent TAVI for severe symptomatic aortic stenosis between December 2008 and June 2019 at 2 international centers and compared all-cause death between the group with mild PVR (group 1) and the group with none or trace PVR (group 2). PVR was categorized using a 3-class grading scheme, and patients with PVR ≧ moderate and those who were lost to follow-up were excluded. This retrospective analysis included 1,404 patients (mean age 81.7 ± 6.5 years, 58.0% women). Three hundred fifty eight patients (25.5%) were classified into group 1 and 1,046 patients (74.5%) into group 2. At baseline, group 1 was older and had a lower body mass index, worse co-morbidities, and more severe aortic stenosis. To account for these differences, propensity score matching was performed, resulting in 332 matched pairs. Within these matched groups, during a mean follow-up of 3.2 years, group 1 had a significantly lower survival rate at 5 years (group 1: 62.0% vs group 2: 68.0%, log-rank p = 0.029, hazard ratio: 1.41 95% confidence interval: 1.04 to 1.91). In the matched cohort, patients with mild PVR had a significant 1.4-fold increased risk of mortality at 5 years after TAVI compared with those with none or trace PVR. Further studies with more patients are needed to evaluate the impact of longer-term outcomes.

Postoperative paravalvular regurgitation (PVR) is an important complication after transcatheter aortic valve implantation (TAVI) and is associated with increased mortality.1Kodali S Pibarot P Douglas PS Williams M Xu K Thourani V Rihal CS Zajarias A Doshi D Davidson M Tuzcu EM Stewart W Weissman NJ Svensson L Greason K Maniar H Mack M Anwaruddin S Leon MB Hahn RT.
