1. A method of treating a patient, comprising:
delivering a self-expandable transcatheter heart valve (THV) over a guidewire in a contracted state and within a sheath to a first anatomical location within a heart of the patient,
wherein the THV includes inflow struts with sharp end regions;
moving the THV relative to the sheath for partially self-expanding a portion of the THV within the first anatomical location, wherein a portion of the THV in the sheath remains in the contracted state and the THV is partially self-expanded,
wherein a distal end of the THV is positioned 3-10 millimeters (mm) from a plane defined as a bottom of cusps of an aortic valve towards a left ventricle;
wherein the portion of the THV that is partially self-expanded includes any of the inflow struts of the THV protruding out of the sheath;
refraining from moving the partially self-expanded THV with any of the inflow struts protruding out of the sheath, relative to an aortic annulus of the heart;
re-collapsing the partially self-expanded portion;
repositioning the distal end of the THV after the re-collapsing to a second anatomical location within the heart 3-10 mm from the plane; and
deploying the THV such that the distal end of the THV is 3-10 mm from the plane.
