Abstract
Abstract Background Transcatheter mitral valve repair (TMVR) has become an important minimally invasive alternative to open surgical repair in patients with severe mitral regurgitation. As TMVR develops as an established practice, real-world outcome data is needed to guide clinical decision making as the body of literature on this topic is limited. In our study, we investigate TMVR outcomes in a large urban health system. Methods We retrospectively analyzed clinical data from the electronic health records of the extensive urban health system Mount Sinai Data Warehouse and analyzed all individuals who underwent TMVR. Baseline demographics were obtained as well as significant morbidity and mortality outcomes. Finally, multivariable analysis was used to determine associated characteristics with mortality. Results We identified 3533 patients who underwent TMVR from 2008 to 2018. The overall mortality was 3.7%. The most common comorbidities observed were heart failure (56%), pulmonary hypertension (26%), atrial fibrillation (26%) and CKD or ESRD (16%). After multivariable analyses, ischemic stroke (adjusted OR 3.46; 95% CI 1.93–5.97, p = <0.001), CKD or ESRD (3.95; 2.72–5.75, p 0.01), aortic stenosis (2.23; 1.12–4.15, p<0.001), and heart failure (8.18; 4.16–18.5, p<0.001) were independently associated with mortality. Conclusion In all patients who underwent TMVR at a large urban health system, ischemic stroke, aortic stenosis, heart failure, CKD and ESRD were independently associated with mortality. Future prospective studies will be needed to further define these observed associations. Funding Acknowledgement Type of funding sources: None.
