Abstract

One method of implanting a prosthetic valve includes advancing the valve into a patient with a delivery apparatus. The valve includes apices circumferentially-spaced apart relative to each other. At least some of the apices include first apertures. The delivery apparatus includes release arms and a sheath. The release arms include second apertures for receiving the apices. At least one of the second apertures of the release arms has a different length than another one of the second apertures. The method also includes positioning the valve at a location, retracting a sheath of the delivery apparatus relative to the valve, allowing the valve to self-expand from a radially compressed state to a radially expanded state, and while the valve is coupled to the delivery apparatus, pivoting the valve relative about the release arms such that an axis of the valve is tilted relative to an axis of the delivery apparatus.
