BACKGROUND: Transcatheter mitral valve implantation (TMVI) may be attractive to treat high-risk patients with mitral bioprosthesis or annuloplasty ring failure or severe mitral annular calcification.
AIM: To report the outcomes of patients after valve-in-valve/ring/mitral annular calcification TMVI using balloon expandable transcatheter aortic valves, according to the degree of urgency of the procedure.
METHODS: All patients who underwent TMVI in our centre from 2010 to 2021 were classified into three groups: elective, urgent or emergent/salvage TMVI.
RESULTS: A total of 157 patients were included: 129 (82.2%) had elective, 21 (13.4%) urgent and 7 (4.4%) had emergent/salvage TMVI. Patients with emergent/salvage TMVI had a higher EuroSCORE II: elective, 7.3%; urgent, 9.7%; emergent/salvage, 54.5% (P<0.0001). The indication for TMVI was bioprosthesis failure in all of the emergent/salvage group, in 13 of the urgent group (61.9%) and in 62 of the elective group (48.1%). Overall, the technical success rate of TMVI was 86%, and was similar in the three groups (elective, 86.1%; urgent, 95.2%; emergent/salvage, 71.4%). The cumulative survival rate at 2-year follow-up was lower in the emergent/salvage group than in the elective or urgent group (42.9% vs 71.2% for the elective group; 76.2% for the urgent group; log-rank test, P=0.012). The excess mortality in the emergent/salvage group occurred during the first month postprocedure. Thereafter, the 30-day landmark analysis did not show any more statistical difference between the three groups (log-rank test, P=0.94).
CONCLUSIONS: Emergent/salvage TMVI was associated with high early mortality, but 1-month survivors had similar outcomes to patients with elective/urgent TMVI. The degree of urgency of the procedure should not prevent TMVI in high-risk patients.
