Background: The primary objective of our study was to evaluate real-world outcomes of Transcatheter mitral valve repair (TMVR) (MitraClip) including in-hospital mortality and short-term readmission rates.
Methods: The study cohort was derived from the National Readmission Data (NRD) 2013. TMVR was identified using appropriate ICD-9-CM codes. Hierarchical two level logistic models were used to evaluate 30-day readmissions and a composite of in-hospital mortality/peri-procedural complications.
Results: We identified 274 (weighted n=537) procedures with 39 (14.2%) readmissions during the study period. 6 patients has open mitral repair and 1 patient had repeat MitraClip during readmission. Multivariate predictors (OR, 95% CI, p-value) of readmission included pre-procedural diagnosis of CHF (3.39, 1.27-9.07, 0.02) or CAD (2.33, 1.04-5.25, 0.04), blood transfusion or permanent pacemaker placement during index admission. Multivariate predictors of in-hospital mortality/complications included female sex (2.48, 1.33-4.62, <0.01), renal failure (4.12, 2.17-7.81, <0.01), neurological disorder (21.14, 6-74.48, <0.01) and use of hemodynamic support during index admission (4.51, 2.11-9.65, <0.01).
Conclusions: Both cardiac and non-cardiac causes accounted for readmission, highlighting a complex population with multiple comorbidities. CHF accounted for only 9 (3%) readmissions, supporting a role of MitraClip in reducing heart failure hospitalizations in this patient population.
