Authors' conclusion

Extravalvular cardiac damage, especially RVD (stage 4), is strongly associated with increased short-term and mid-term mortality and rehospitalisation after TAVI. Even borderline-stage patients face elevated risk, underscoring the continuous nature of AS-related cardiac injury. Incorporating cardiac damage staging into preprocedural assessment can enhance risk stratification and guide management to improve patient outcomes.

Study context

Population
Adults with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI), stratified by presence of right ventricular dysfunction (RVD), pulmonary hypertension (PH) or tricuspid regurgitation (TR)
Participants
26,076 adults · 34 studies
Comparison
Outcomes after TAVI stratified by the presence of RVD, PH or TR
