Prognostic value of right ventricular dysfunction in patients undergoing transcatheter aortic valve replacement

Abstract Introduction Right ventricular dysfunction (RVD) in patients with severe aortic stenosis seems to increase the risk of worse long-term outcomes after transcatheter valve replacement (TAVR). The purpose this study was investigate association between RVD at baseline and prognosis TAVR (readmission for heart failure death). Methods A cohort conducted. Consecutive undergoing from January 2012 December 2020 were included analysed depending on right function prior procedure. assessed using tricuspid annular plane systolic excursion (≤17 mm). Clinical follow-up characteristics recorded. median 26±22 months. Results Of 292 who underwent TAVR, 64 (21.9%) met criteria baseline. Patients significantly more often male (65% vs 46%) smokers or former (42% 23%). They had a higher EuroScore score (9.1±7.2 5.3±4) greater prevalence atrial fibrillation (55% 32%), previous surgery (20% 4%) pacemaker implant (25% 14%), less left ejection fraction (48±15% 58±11%), lower mean gradient (41±13 50±13 mmHg) estimated pulmonary artery pressure (50±18 42±13 compared preserved RV function. Procedural complications similar both groups. Normalization found 50.8% Readmission during common (29.7% 13.3%, p 0.04), also observing trend terms mortality 19.1%, 0.08). Conclusions an increased readmission mortality. Funding Acknowledgement Type funding sources: None.
