Design and Rationale of the National Multicenter Tunisian Registry of Trans Catheter Aortic Valve Implantation Registry

Transcatheter aortic valve implantation (TAVI) has emerged as a transformative therapy for patients with severe aortic stenosis, particularly those designated high-risk or inoperable for traditional surgical valve replacement. Despite its increasing adoption worldwide, there re-mains a paucity of data regarding TAVI outcomes in Tunisian patients. In response to this gap in knowledge, the investigators propose the establishment of the Tunisian TAVI Registry, a multicenter initiative aimed at comprehensively documenting the clinical characteristics, procedural de-tails, and short- and long-term outcomes of TAVI procedures across Tunisia. The TAVI.TN registry will enroll consecutive patients undergoing TAVI procedures at participating centers across Tunisia, between 2013 and 2024 with a retrospective arm and a prospective arm. The TAVI-TN Registry represents a significant step towards enhancing our understanding of TAVI outcomes in the Tunisian population. By systematically capturing real-world data, this initiative aims to inform clinical decision-making, improve patient care, and contribute to the advancement of TAVI practices in Tunisia and beyond.
