Pre- and postoperative tricuspid regurgitation in patients with severe symptomatic aortic stenosis: importance of pre-operative tricuspid annulus diameter

Secondary tricuspid regurgitation (STR) is commonly found in patients with aortic stenosis and is associated with increased morbidity. The study sought to evaluate the prevalence of pre-operative STR and its progression after surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI). Also, it sought to analyse the predictors of post-operative changes in STR.
