Abstract
A method and device for perforating an aortic valve to remove excessive calcium deposits on aortic valve leaflets improves the implantation of TAVI replacement valves in patients. By removing excessive calcium deposits, the radial pressure exerted by implanted TAVI replacement valves is reduced, such that there is less blood leakage around the valve and less stress on the cardiac conductive system. A device with a collapsible punch is inserted into the aortic valve. The punch is separable such that the aortic valve leaflets are positioned between at least two elements of the punch. The two elements then compress together with the leaflets between them, causing the aortic valve to be perforated. A circumferential ring of the remaining aortic valve and calcium deposits are left to provide stability for the TAVI replacement valve.
