ABSTRACT
BACKGROUND: Transcatheter mitral valve replacement (TMVR) using the Tendyne™ valve is regarded as one of the most studied TMVR systems. The first human experience with the procedure was reported in 2013. The present study aims to systemically revise the published literature to document the global experience with TMVR using the Tendyne™ valve. METHODS: The present review was conducted in line with the PRISMA statement on systematic reviews. Database included in the search process were Scopus, Web of Science and Pubmed. Search was processed using multiple keywords combinations and was adjusted to English literature only. RESULTS: We included 26 articles in the final analysis reporting data from 319 patients. Patients recruited by the included studies comprised 192 males (60.2%) and 127 females (39.8%). In the studied patients, mitral annular calcification (MAC) was reported in 107 patients (33.5%). Preoperatively, MR grades 1,2 and 3-4 were reported in 3,5 and 307 patients respectively. Postoperatively, MR grades 1, 2 and 4 were reported in only 12, 3 and 1 patients respectively. Technical success was achieved in 309 patients (96.9%). Follow up durations widely varied among different studies from just days before discharge to 6 years. At the end of follow up, 79 patients died (24.8%) including 52 patients (16.3%) due to cardiovascular causes. CONCLUSIONS: Management of mitral valve disease using the Tendyne system appears to be a promising minimally invasive option for many high-risk patients with accepted procedural feasibility and safety profile.
