- Abstract
Purpose: Coronary catheterization after transcatheter aortic valve implantation (TAVR) may be challenging. The main objective of the study is to assess the feasibility of coronary catheterization and angioplasty according to each type of valve., Patients and Method: We retrospectively studied coronary angiography or percutaneous angioplasty procedures after TAVR in two different centers. The catheterization success of coronary artery was evaluated according to the quality of engagement in ostium and opacification of the artery. Other indicators were collected including catheters used, fluoroscopy and angiography times, DAP and the volume of the contrast agent., Results: Among 1512 TAVR procedures, 33 patients were included. The Sapien 3® valve was implanted in 22 patients and the Evolut® in 11 patients (7 Evolut-R® and 4 Evolut Pro®). Coronary angiography with selective or partially selective catheterization has been successfully performed in all patients with a Sapien 3® valve. In the Evolut® group we identified 3 cases of non-selective catheterization for the right coronary and 1 case for the left coronary. Standard Judkins catheters seem to be the most suitable for both types of valve with very good efficiency., Conclusion: The results of our study is promising for the future of TAVR with a coronary catheterization success rate close to 100% with some difficulties for the Evolut® supra-annular valves. Special attention should be paid to the technique of implantation and orientation of cups in the aortic sinus., Competing Interests: Conflit d'intérêt aucun, (Copyright © 2021 Elsevier Masson SAS.
