BACKGROUND: Little is known about the association of heart failure (HF) chronicity with clinical outcomes after transcatheter mitral valve repair (TMVR) for functional mitral regurgitation (MR).
METHODS: From January 2011 to March 2019, consecutive patients with functional MR who underwent a MitraClip procedure were analyzed. The patients were divided into two groups according to HF duration-those with duration ≤18 months and those with >18 months. The primary outcome measure was a composite of all-cause mortality and re-HF rehospitalization within 1 year after the procedure. These outcomes were also assessed separately. A Cox proportional hazard model was conducted for investigating the association of HF duration with the primary outcome.
RESULTS: A total of 208 patients were analyzed. Patients with HF duration >18 months had a higher rate of the primary outcome compared to those with HF duration ≤18 months (38.1 vs. 19.0%, log-rank p = .003). A longer duration of HF was associated with an increased risk of the primary outcomes (adjusted-HR of >18 months, 2.12 95% CI, 1.14-4.19; p = .03; adjusted-HR (hazard ratios) for 1 year increase, 1.05; 95% CI, 1.02-1.09; p = .004). The association of HF duration with the primary outcomes showed a steep rise during the first 2 years of HF duration and progressive increase after 5 years.
CONCLUSIONS: A longer HF duration before TMVR was associated with an increased risk of all-cause mortality or HF rehospitalization. HF duration can be used for the risk stratification marker in patients undergoing TMVR for functional MR.
