This study sought to determine the potential change in trends in the baseline characteristics of patients with symptomatic severe mitral regurgitation who underwent transcatheter edge-to-edge mitral valve repair (M-TEER) over the last decade in a high-volume center.
The investigation included 942 symptomatic patients with moderate-to-severe and severe mitral regurgitation who underwent transcatheter edge-to-edge repair (TEER) at our institution between January 2010 and March 2021. Patients were divided into quintiles and compared separately.
Patients treated in the last quintile had significantly lower surgical risk (Euro Score 7.2 ± 6.8% in the last quintile vs. 10.9 ± 9.4% in the first quintile,
Patients undergoing the M-TEER procedure nowadays have lower surgical risk and are treated before they develop a significant left ventricular (LV) remodeling than before. The increasing expertise on the procedure over the last decade led to a rising number of patients with complex degenerative pathology being treated.
