Surgical procedure showing aortic valve replacement using a Portico valve with a stent frame. Used in patients with aortic stenosis. A cross section of the heart is shown with a focus on the ascending aorta between the atria. A catheter is advanced into the left ventricle. The transcatheter heart valve is unsheathed and can be repositioned if necessary. This feature reduces the risk of embolization, coronary obstruction and atrioventricular block.
