1. A prosthetic heart valve for replacement of a native valve of a patient, wherein the prosthetic heart valve comprises:
- an expandable generally tubular stent support forming a wire frame and having proximal end, a proximal portion, a medial portion, a distal portion, and a distal end, an interior area, a longitudinal axis extending from the proximal end to the distal end, and a circumference, wherein the proximal end and the distal end each comprises a crown of a plurality of free peaks pointing in the proximal and distal direction, respectively, and wherein the tubular stent support comprises a plurality of adjacent rows of interconnected diamond-shaped cell structures extending between the proximal end and distal end, wherein a diamond-shaped cell structure is formed of two intersection points that are spaced from each other along the longitudinal axis of the stent support, forming the peaks of one row, and of two intersection points that are spaced from each other relative to the circumference of the stent support, wherein a last row at the distal end comprises only three diamond-shaped cell structures, which are spaced from each other around the circumference of the stent support, such, that they do not touch each other; and
a valve structure having a plurality of valve leaflets, a valve skirt, and a plurality of valve commissure points, and wherein the valve structure is attached within the interior area of the stent support, such that in the proximal portion the inner surface of the tubular stent support is lined with the valve structure forming a sealing zone, such that the valve structure, in a region between the distal end and the medial portion, is fixed to the stent support via the commissure points, and such that the stent support has, in a region between the distal end and the medial portion, a valve-free portion;
wherein the distal end of the stent support, in its crown, has only three free peaks all of which peaks have a connecting wire extension structure, the connecting wire extension structure having a first wire section substantially parallel to the longitudinal axis and having a generally longitudinal shape extending from the distal end in the proximal direction, and having a second wire section at least a portion of which extends in a direction perpendicular to the longitudinal axis.

Abstract
The present invention relates to a prosthetic heart valve, the prosthetic heart valve comprising a generally tubular stent support and a valve structure. The stent support comprises multiple rows of diamond-shaped cell structures and crowns at its distal and proximal end, as well as three V-shaped openings which open towards the distal end of stent support.
