Key result
This editorial discusses a study evaluating the impact of transcatheter aortic valve implantation on mitral regurgitation severity across different aetiologies (aFMR, vFMR, and PMR).
Why the study?
How does mitral regurgitation aetiology impact outcomes and changes in MR severity after TAVI in patients with coexisting aortic stenosis and MR ≥2?
How does mitral regurgitation aetiology impact outcomes and changes in MR severity after TAVI in patients with coexisting aortic stenosis and MR ≥2?

This editorial highlights the importance of categorizing mitral regurgitation etiology to understand its improvement and impact on outcomes following TAVI for aortic stenosis.
Not infrequently, mitral regurgitation (MR) coexists with aortic stenosis (AS).It is also well known from papers and clinical practice that in some patients, pre-existing mitral regurgitation improves after transcatheter aortic valve implantation (TAVI) for the treatment of AS.In this issue of EuroInvention, the article by Doldi and colleagues, "Impact of mitral regurgitation aetiology on the outcomes of transcatheter aortic valve implantation" 1 , analyses outcomes and changes in mitral regurgitation (MR) severity, with different aetiologies, after TAVI.For this study, all patients showing MR ≥2 were categorised, depending on the MR aetiology into three groups: atrial functional mitral regurgitation (aFMR), ventricular functional mitral regurgitation (vFMR) and primary mitral regurgitation (PMR) following TAVI.

Gómez et al. (2023) conducted an editorial in Aortic stenosis with coexisting mitral regurgitation. Transcatheter aortic valve implantation (TAVI) was evaluated on Outcomes and changes in mitral regurgitation severity. This editorial discusses a study evaluating the impact of transcatheter aortic valve implantation on mitral regurgitation severity across different aetiologies (aFMR, vFMR, and PMR).
