Highlights
- •The influence of mitral regurgitation (MR) on transcatheter aortic valve replacement procedure was studied using the Japan-TVT registry.
- •1-year follow―up data were obtained from 25,979 patients (follow-up rate 98.5 %).
- •Propensity-score matching was employed.
- •Survival was similar among patients with or without moderate or severe MR.
- •Death and/or heart failure occurred more in patients with moderate or severe MR.
Abstract
Background
We investigated the influence of concomitant mitral regurgitation (MR) in patients
undergoing transcatheter aortic valve implantation on the 1-year outcome using Japan
Transcatheter Valve Therapy (J-TVT) registry data.
Methods
The patients who underwent the transcatheter aortic valve implantation for aortic
stenosis performed from August 2013 to December 2019 in Japan were included. History
of previous valve surgery and dialysis patients were excluded. A total of 24,979 patients
were included, and 1-year follow-up data were obtained from the registry (follow-up
rate 98.5 %). Propensity-score matching, using multivariable logistic regression and
1:1 matching without replacement, was performed between the patients with grade 3–4
MR (MR 3–4 group) and those with grade 0–2 MR (MR 0–2 group). All-cause death and
the composite outcome of death and/or heart failure events were compared.
Results
After propensity score matching, 3920 cases (1960 cases each in MR 0–2 group and MR
3–4 group) were extracted. The procedure success rate was 96.4 % in MR 0–2 and 96.0 %
in MR 3–4 group (p = 0.56) and the surgical conversion rate was 0.7 % in MR 0–2 group and 0.8 % in MR
3–4 group (p = 0.58). Cox regression model showed no statistical difference in 1-year survival
rate between MR 0–2 group (89.4 %) and MR 3–4 group (89.6 %) (p = 0.80). However, freedom from 1-year death and/or heart failure event was lower
in MR 3–4 (86.3 %) than in MR 0–2 group (88.9 %) (p = 0.01). This trend was also found in the subgroup of New York Heart Association
(NYHA) class 1–2 but not in the subgroup of NYHA class 3–4.
Conclusions
One-year survival rate was not different between groups but freedom from death and/or
heart failure events was lower in patients with preoperative MR grade 3–4 than in
patients with preoperative MR grade 0–2 after transcatheter aortic valve replacement.
