Background: Decreasing Right Ventricular (RV) and Left Ventricular (LV) function after surgical or transcatheter
aortic valve replacement (SAVR or TAVR, respectively) is an important risk factor for morbidity and mortality.
Although Transapical (TA)-TAVR is an independent risk factor for post-procedural mortality, limited knowledge is
available regarding long-term changes in RV and LV function. The study aimed to evaluate LV and RV performance
following four different AVR procedures, including TA-, Transfemoral (TF)-TAVR, and SAVR with and without
coronary artery bypass grafting (± CABG).
Methods: Patients with severe AS were consecutively included and assigned to TA-TAVR, TF-TAVR, or SAVR ± CABG
groups. A total of 130 patients underwent preoperative conventional and strain-rate-imaging echocardiography, with
