Background: Right ventricular (RV) function is often not taken into consideration in the prognostication of patients undergoing transcatheter aortic valve replacement (TAVR); accordingly its impact on patients undergoing TAVR remains relatively poorly defined. We sought to explore the effect of various parameters of RV function on 30-day outcomes in patients undergoing TAVR.
Methods: We collected baseline demographic and hemodynamic data obtained by routine right heart catheterization (RHC), pre- and day 1 post TAVR, on 460 patients undergoing TAVR at our institution between 2012 and 2015. Our primary end-point was 30-day rate of all-cause mortality and/or hospital readmissions.
Results: There were 25 deaths and 40 readmissions within 30 days of TAVR. Univariate analysis showed higher STS score, chronic kidney disease, high mean PA pressures, prolonged intubation post TAVR, severe pre-operative MR and TR were associated with statistically significant higher 30-day mortality and/or readmission rates. On multivariate analysis, STS score (OR 1.07, 95% CI 1.012 – 1.126), moderate TR (OR 3.24, 95% CI 1.52 – 6.87), and severe TR (OR 2.5, 95% CI 1.04 – 6.04) were identified as significant predictors of 30 day mortality or readmission rates. RVSWI was not found to be a significant predictor of primary end-point.
Conclusions: STS score and severity of tricuspid regurgitation were strongest independent parameters predictive of death or readmission at 30 days. Therefore, parameters of RV function such as TR should be tested further and incorporated into predictive models for patients undergoing TAVR.
