Impact of Right Ventricular Dysfunction and Tricuspid Regurgitation on Outcomes in Patients Undergoing Transcatheter Aortic Valve Replacement.
Right ventricular (RV) dysfunction and tricuspid regurgitation (TR) may coexist with aortic stenosis. The aim of this study was to assess the association between RV dysfunction, TR, associated comorbidities, and outcomes following transcatheter aortic valve replacement (TAVR). ⋯ TR in association with aortic stenosis is frequently progressive despite TAVR but is not independently associated with outcomes. RV function is a stronger driver of adverse outcomes compared with TR itself, and RV quantitative rather than qualitative evaluation is the key to stratify these patients.
