Outcomes of emergency compared to elective TAVI: A meta-analysis

Abstract

Introduction and objectives: Transcatheter aortic valve implantation (TAVI) has proven safe and effective in low-to-high risk patients, but emergency procedures have been excluded from the landmark trials. We aimed to assess the current outcomes and main factors conditioning the prognosis during emergency TAVI. Methods: A systematic search in PubMed and Google Scholar was conducted for all studies comparing elective vs emergency TAVI. Searched terms were “emergency” and/or “urgent”, “elective”, and “transcatheter valve replacement” and/or “heart failure” and/or “cardiogenic shock”. Emergency TAVI was considered as any unscheduled TAVI performed to treat refractory heart failure or cardiogenic shock. A random-effects model was used. Results: A total of 7 studies with 84 427 TAVI patients were included (14241 emergency procedures; 70186 elective TAVIs). Emergency cases presented higher risk scores (logistic EuroSCORE 65.9% ± 21% vs 29.4% ± 18%, P
