Interventional Anatomy of Aortic Valve



The knowledge of aortic root anatomy is relevant in the current era of interventional therapeutic strategies for aortic valve disease, through transcatheter aortic valve implantation (TAVI). In this procedure, the native aortic valve is crushed against the aortic wall and into the sinuses of Valsalva via either a transapical (through the left ventricular apex) or a transarterial catheter by a balloon- or self-expandable stent carrying a bioprosthetic valve. Anatomic factors influencing a safe and proper device deployment during TAVI include annular diameters, sinuses of Valsalva dimensions, and coronary ostia location; calcium deposits size (bulkiness) and location; subaortic septum thickness and morphology; and relationship with the membranous septum and the mitral valve.

The aim of the present chapter is to review the anatomy of the aortic root relevant for interventional cardiologist to avoid risk of complications, such as prosthesis embolization, improper positioning, coronary obstruction, paravalvular regurgitation, annular and root rupture, conduction system disturbances, and mitral valve injury.
