OBJECTIVES: The aim of this study was to compare outcomes of transcatheter intervention (TI) versus surgical intervention (SI) for paravalvular leak (PVL). BACKGROUND: Data comparing the treatment of PVL with TI and SI are limited. METHODS: A retrospective cohort study was conducted comparing baseline characteristics, procedural details, and 1-year survival in consecutive patients who underwent TI or SI for moderate or greater PVL from 2007 to 2016. The primary outcome was a composite of death, reintervention for PVL, or readmission for congestive heart failure-related symptoms at 1 year. RESULTS: Of 114 patients, 56 underwent TI and 58 underwent SI. PVL locations were mitral, aortic, and pulmonary in 69 (60.5%), 39 (34.2%), and 6 (5.3%) patients, respectively. At baseline, TI patients were older (age 71 vs. 62 years; p = 0.010) and had fewer cases of active endocarditis (0.0% vs. 25.9%, p < 0.001) than SI patients. The TI group had a shorter post-operative stay (4 vs. 8 days; p < 0.001), a shorter intensive care unit stay (0 vs. 3 days; p < 0.001), and fewer readmissions at 30 days (8.9% vs. 25.9%; p = 0.017). There were no differences in the primary endpoint (TI 33.9% vs. SI 39.7%; p = 0.526) or 1-year survival (TI 83.9% vs. SI 75.9%; p = 0.283) between groups. CONCLUSIONS: In this study, TI for PVL closure had comparable 1-year clinical outcomes with SI, even after adjusting for differences in baseline characteristics, with less in-hospital morbidity and 30-day rehospitalization. Although further study is needed, these findings support the increased implementation of TI for PVL closure at experienced institutions.
