TAVI Without On-Site Cardiac Surgery in Poland: A Randomized Multicenter Trial Protocol
Starting soon · Not applicable
Conditions studied: Aortic Stenosis
In brief
Aortic stenosis (AS) represents the most prevalent acquired valvular heart disease in European populations, and transcatheter aortic valve implantation (TAVI) has become the dominant treatment modality for patients with symptomatic severe AS. The latest 2025 ESC guidelines have broadened age-related eligibility, while the procedure still continues to be limited to centres with cardiac surgery on-site (CSOS). This limitation is in place, despite the very low rate of complications requiring emergent surgical conversion. This subsequently, may constrain procedural capacity and contribute to prolonged waiting times, which in turn are associated with increased pre-procedural mortality and heart failure-related hospitalizations. This prospective randomized open-label clinical trial aims to evaluate the safety and feasibility of performing TAVI in selected pilot centers operating without on-site cardiac surgery department (no-CSOS). Selected patients with severe native AS deemed suitable for transfemoral TAVI by a Heart Team will be enrolled. No-CSOS centers must meet predefined criteria, including operators experience, hybrid operating room availability, on-site vascular surgery availability, and established rapid transfer pathways to CSOS centers. The primary endpoint of the study is early 30-day safety based on VARC-3 criteria; secondary endpoints include additional composite outcomes. Patients will be randomly assigned in a 1:1 ratio using a central Web-based system to undergo TAVI either at a CSOS or non-CSOS site. A total of 404 patients (202 per group) is required. The study will inform national strategies and contribute to defining contemporary safety standards for TAVI delivery in no-CSOS centres.
