Abstract
Background: Transcatheter mitral valve repair and replacement (TMVR) is a minimally invasive alternative to conventional open-heart mitral valve replacement (OMVR). The present study aims to compare the burden, demographics, cost, and complications of TMVR and OMVR.
Methods: The United States National Inpatient Sample (US-NIS) for the year 2017 was queried to identify all cases of TMVR and OMVR. Categorical and continuous data were analyzed using Pearson chi-square and independent t-test analysis, respectively. An adjusted odds ratio (aOR) based on the ordinal logistic regression (OLR) model was calculated to determine the association between outcome variables.
Results: Of 19,580 patients, 18,460 (94%) underwent OMVR and 1120 (6%) TMVR. Mean ages of patients were 63 ± 14 years (OMVR) and 67 ± 13 years (TMVR). Both cohorts were predominantly Caucasian (73% OMVR vs. 74.0% TMVR). The patients who underwent TMVR were more likely to belong to a household with an income in the highest quartile (26.1% vs. 22.0% for OMVR) versus the lowest quartile (22.1% vs. 27.8%). The average number of days from admission to TMVR was less compared to OMVR (2.63 days vs. 3.02 days, p = 0.015). In-hospital length of stay (LOS) was significantly lower for TMVR compared to OMVR (11.56 vs. 14.01 days, p=<0.0001). Adjusted in-hospital mortality taking into account comorbidities showed no significant difference between the two groups (OR 1.2, 0.93-1.68, p = 0.15).
Conclusion: Patients undergoing TMVR were older and more financially affluent. TMVR was more costly but was associated with a shorter hospital stay and similar mortality to OMVR.
