Differential Impact of TAVR and SAVR on Right Ventricular Function in Patients with Severe Aortic Stenosis: A Six-Month Follow-Up Study

Abstract

Background: Pulmonary hypertension (PH) frequently coexists with severe aortic stenosis (AS) and contributes to adverse perioperative and long-term outcomes after aortic valve replacement (AVR). Understanding the hemodynamic changes in pulmonary artery pressures following surgical AVR (SAVR) and transcatheter aortic valve implantation (TAVI) is essential for prognostic evaluation and treatment planning.
