Percutaneous Aortic Valve Replacement

Percutaneous aortic valve replacement (PAVR),is also known as transcatheter aortic valve implantation (TAVI) or transcatheter aortic valve replacement (TAVR), which is a replacement of the aortic valve of the heart through the blood vessels (as opposed to valve replacement by open heart surgery). Replacement valve will transfered through some of the  several access methods such as transfemoral (in the upper leg), transapical (through the wall of the heart), subclavian (beneath the collar bone), direct aortic (through a minimally invasive surgical incision into the aorta), and transcaval (from a temporary hole in the aorta near the belly button through a vein in the upper leg).

Severe symptomatic aortic stenosis will carry a poor prognosis .The risks associated with surgical aortic valve replacement are increased mainly in elderly patients and those with the concomitant severe systolic heart failure or coronary artery disease, as well as in people with comorbidities such as cerebrovascular and peripheral arterial disease, chronic kidney disease, and chronic respiratory dysfunction.
