Outcomes of Transcatheter Aortic Valve Implantation in Patients With Low Versus Intermediate to High Surgical Risk

Referral of low surgical risk (LSR) patients for transcatheter aortic valve implantation (TAVI) becomes common in multiple tertiary centers, and clinical trial data for this population are not available to date. We performed a retrospective analysis on an Israeli multicenter registry. LSR and intermediate-high surgical risk (I-HSR) were defined by a Society of Thoracic Surgery score of 0.05 for all comparisons), the safety outcome at 1 month (12.7% vs 9.8%), procedural mortality (1.9% vs 0.6%), and mortality at 3 years (30.1% vs 16.1%) were higher in patients with I-HSR (p
