Transcatheter aortic valve prostheses for improving the cardiac function of a patient suffering from coronary artery disease. Transcatheter aortic valve prostheses include a valve component and a frame. The valve component includes valve leaflets and a skirt. The frame includes access cells that improve access to a patient's coronary arteries if further intervention is required and/or includes a window or conduction protection cell that is oriented to align with a portion of conduction system of the heart in situ to reduce conduction disturbances of the anatomy. Suture patterns for attaching a commissure to a commissure post of the frame, and for attaching a tissue bumper to the commissure post, are also described.

Novel tools and techniques are provided for implementing protection of at least one tissue layer of a medical device or implant during crimping of the medical device or implant. In various embodiments, an implant tissue protection tool may include an outer portion configured to surround one or more outer segments of at least one tissue layer of a medical device to be implanted into a body of a subject and at least one protrusion (which may be affixed to a surface of the outer portion) configured to minimize or prevent occurrence (or likelihood of occurrence) of the at least one tissue layer (in some cases, leaflet material, or the like) of the medical device passing through at least one opening defined by a frame structure of the medical device during crimping of the medical device by a crimping device in preparation for implantation into the body of the subject.

A transcatheter valve prosthesis includes a stent and a prosthetic valve. The stent includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. The transition portion includes a plurality of axial frame members, and three of the plurality of the axial frame members are commissure posts. At least two of the plurality of the axial frame members are commissure posts having a first end connected to a crown of the inflow portion and an unattached second end disposed within the outflow portion such that a pair of struts of the outflow portion intersect each commissure post at a mid-portion thereof. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent.
