Abstract
Transcatheter aortic valve replacement (TAVR) has become the treatment of choice for patients with severe symptomatic aortic stenosis who are not candidates or at high risk for aortic valve replacement (AVR) surgery. The CoreValve has been extensively used worldwide and has recently been approved by the FDA for commercial use in the USA. The CoreValve is a transcatheter valve composed of porcine pericardial leaflets mounted on a self-expanding nitinol stent. The CoreValve comes in four sizes (23, 26, 29, and 31 mm) accommodating aortic annulus with mean diameters from 18 mm to 29 mm. Transfemoral is the most common delivery route for the CoreValve, and it is associated with the best outcomes. In this chapter, we describe the CoreValve and its delivery system. We provide a detailed description of the preprocedure evaluation of the aortic root, aorta, and iliofemoral arteries by multidetector computed tomography and of the anatomic criteria essential for prosthesis size and access selection. This chapter also provides a step by step description of the CoreValve deployment process with hints to avoid common problems and a review of the outcomes of the US CoreValve Pivotal trial.
