Coronary artery disease (CAD) is often present in patients with severe aortic valve stenosis candidates to transcatheter aortic valve implantation (TAVI). Mild CAD may also worsen and need treatment years after TAVI. The implantation of a transcatheter valve may interfere with the capability of reengaging the coronary arteries. We prospectively assessed the feasibility of performing coronary angiography (CA), fractional flow reserve, and, where indicated, percutaneous coronary intervention after valve implantation in a consecutive series of patients with CAD undergoing TAVI. Valve type and size were decided according to accurate computed tomography scan and angiographic measurement of the aortic root structures. We analyzed 66 consecutive patients undergoing TAVI, 41 with balloon expandable, and 25 with self-expandable transcatheter valves. Right and left coronary catheterization (132 vessels) was successful in all cases except in 1 left coronary artery after a high implantation of a self-expandable valve (unsuccess rate, 1 in 50 vessels). In 6 of 132 vessels (4%), CA was initially nonselective, but after positioning the 0.014 '' intracoronary guidevvire, selective injections were obtained in all these cases.

Abstract

Coronary artery disease (CAD) is often present in patients with severe aortic valve stenosis candidates to transcatheter aortic valve implantation (TAVI). Mild CAD may also worsen and need treatment years after TAVI. The implantation of a transcatheter valve may interfere with the capability of reengaging the coronary arteries. We prospectively assessed the feasibility of performing coronary angiography (CA), fractional flow reserve, and, where indicated, percutaneous coronary intervention after valve implantation in a consecutive series of patients with CAD undergoing TAVI. Valve type and size were decided according to accurate computed tomography scan and angiographic measurement of the aortic root structures. We analyzed 66 consecutive patients undergoing TAVI, 41 with balloon expandable, and 25 with self-expandable transcatheter valves. Right and left coronary catheterization (132 vessels) was successful in all cases except in 1 left coronary artery after a high implantation of a self-expandable valve (unsuccess rate, 1 in 50 vessels). In 6 of 132 vessels (4%), CA was initially nonselective, but after positioning the 0.014 '' intracoronary guidevvire, selective injections were obtained in all these cases. Percutaneous coronary intervention was performed successfully in 19 coronary vessels (17 patients) as indicated by fractional flow reserve measurements: In conclusion, catheterization of the coronary ostia after transfemoral TAVI with balloon or self-expandable valves is safe and feasible in almost all cases. Accurate imaging of the aortic root and procedural planning may help to avoid too high implantation of supra-annular self-expandable valves to obviate difficulties in accessing coronary ostia. Use of intracoronary guidewires facilitates selective CA in cases with difficult access. (C) 2016 Elsevier Inc. All rights reserved.
