Prevalence and Prognostic Significance of Right Ventricular Dysfunction in Patients With Severe Low‐Flow, Low‐Gradient Aortic Stenosis Undergoing Transcatheter Aortic Valve Replacement

Background Whether the presence of right ventricular (RV) dysfunction may influence the clinical outcome of patients with low‐flow, low‐gradient aortic stenosis (LFLG‐AS) undergoing transcatheter aortic valve replacement (TAVR) has not yet been established. Methods and Results This study included consecutive patients with LFLG‐AS undergoing TAVR at 2 high‐volume Italian centers. RV dysfunction before TAVR procedure was defined as tricuspid annular plane systolic excursion assessed by transthoracic echocardiography lower than
