    Abstract:
    OBJECTIVES: To summarize the published data of combined transcatheter aortic and mitral valve intervention (CTAMVI). BACKGROUND: CTAMVI, a combination of either transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve-in-valve (TAViV) and transcatheter mitral valve replacement (TMVR), transcatheter mitral valve-in-valve/valve-in-ring (TMViV/ViR), or percutaneous mitral valve repair (PMVR) is an attractive alternative in high-surgical risk patients with combined aortic and mitral valve disease. However, its procedural details and clinical outcomes have not been well described. METHODS: We performed a systematic review of all the published articles from PUBMED and EMBASE. RESULTS: A total of 37 studies with 60 patients were included. The indication for CTAMVI was high or inoperable surgical risk and symptomatic severe aortic stenosis (92%) or severe aortic regurgitation (8%) combined with moderate to severe/severe mitral stenosis (30%) or moderate/severe mitral regurgitation (65%) or both (5%). In majority of the cases, aortic valve intervention was performed prior to the mitral valve. Mortality rate were 25% for TAVR + TMVR (range 42 days to 10 months), 17% for TAVR + TMViV/ViR (range 13 days to 6 months), 0% for TAViV + TMViV/ViR (range 6-365 days), and 15% for TAVR/ViV + PMVR (range 17 days to 419 days). Significant (more than moderate) paravalvular regurgitation post-procedure was rare. CONCLUSIONS: CTAMVI appears to confer reasonable clinical outcome. Further large study is warranted to clarify the optimal strategy, procedural details and clinical outcomes in the future.
