ABSTRACT
During transcatheter edge-to-edge repair (TEER), the reduction of functional mitral regurgitation (FMR) severity, compared with baseline evaluation, is not uncommon. Because the procedural strategies are mainly guided by the location and severity of the regurgitant jets, intraprocedural downgrading (ID) of regurgitation severity could affect the procedural strategy and the results. The aim of this study was to evaluate the prevalence of ID during TEER and to compare early and midterm outcomes in patients with and without ID. All patients with moderate-to-severe or severe FMR who underwent TEER in San Raffaele Hospital between 2018 and 2020 were evaluated in this single-center, retrospective study. ID was defined as mild (1+) or moderate (2+) regurgitation degree during intraprocedural evaluation. The outcomes, assessed at discharge and at 2 years of follow-up, were all-cause mortality, heart failure hospitalization, and recurrence of mitral regurgitation >2+. The final study cohort included 55 patients 42% presented with ID. At discharge, 85.5% of patients achieved regurgitation reduction to 2+ or less 100% in patients with ID versus 75% in patients without ID, p <0.009. At 2 years, no significant difference in the incidence of all-cause mortality, heart failure hospitalization, and the recurrence of mitral regurgitation >2+ between patients with ID or without ID was found. In conclusion, ID is frequent during TEER in FMR. No baseline characteristics were found to identify this group of patients. In patients with ID, the combination of live intraprocedural imaging and baseline ambulatory assessment of regurgitant jets seems effective in the procedural guiding to achieve a successful and durable mitral repair.
