How can pre-procedural imaging and prosthesis selection prevent coronary occlusion and aortic root rupture during TAVI?
Pre-procedural imaging and careful prosthesis selection are critical for preventing rare but highly fatal complications like coronary occlusion and aortic root rupture during TAVI.

Coronary occlusion and rupture of the aortic root or annulus remain two major concerns of transcatheter aortic valve implantation technique. Despite their relatively low frequency they raised the interest of the scientific community as they carry an extremely poor prognosis. Prosthesis type and size selection is part of the patient selection process that allows the operator to prevent these complications. In this article, the techniques used either during pre-TAVI screening or during the procedure itself to avoid coronary occlusion and aortic rupture will be discussed.

A 2015 study conducted a review in Severe aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). Transcatheter aortic valve implantation (TAVI) with pre-procedural imaging (MDCT) and tailored prosthesis selection was evaluated on Coronary occlusion and aortic root/annulus rupture. Pre-procedural multidetector CT imaging and appropriate prosthesis sizing mitigate rare TAVI complications like coronary occlusion and annular rupture.
