Abstract

The pattern and reasons for re-hospitalization (RH) after MitraClip implantation are not well characterized. A total of 322 consecutive MitraClip patients were included, with data stratified by RH status. Multivariate analyses were conducted to identify predictors of early (30-day) and late (30-day to 12-month) RH. Eighty-nine patients (27.6%) were readmitted to hospital during the study period and early RH occurred in 27%. The median time from MitraClip to RH was 99 days. RH was mostly related to cardiovascular causes (66.3%). Anemia and gastrointestinal bleeding were the most frequent noncardiovascular causes. Independent predictors of early RH were length of stay ≥3 days during the index procedure (odds ratio [OR] 4.13, 95% confidence interval [CI] 1.32 to 12.91), reduction of left ventricular ejection fraction ≥5% after MitraClip implantation (OR 4.88, 95% CI 1.36 to 18.91), and severe systolic pulmonary artery pressure ≥60 mm Hg at discharge (OR 3.72, 95% CI 1.23 to 11.26). Conversely, the independent predictors of late RH were device failure (OR 4.02, 95% CI 1.22 to 13.25) and systolic pulmonary artery pressure ≥60 mm Hg at discharge (OR 2.34, 95% CI 1.01 to 5.44). In patients with early RHs, survival was significantly worse at 12 months compared with patients with late RH and no-RH (69.3% vs 82.6% vs 86%, p <0.001). In conclusion, RH is not uncommon after MitraClip implantation and cardiovascular causes represent its most frequent etiology. Clinical and echocardiographic predictors of early and late RH can be identified at discharge. Early RH carries a worse prognosis than late RH.
