1. A stented prosthetic heart valve comprising:

  • a stent post frame including a continuously formed rail forming a closed-curve shape defining a central longitudinal axis, the closed-curve shape including a plurality of circumferentially-spaced posts projecting from, and interposed between cusp segments in a direction of the longitudinal axis, the rail defining a major axis and a minor axis perpendicular to the major axis, the rail having a major axis dimension greater than a minor axis dimension;

    wherein a first one of the posts is defined by spaced apart, first and second leg portions and a tip, the first leg portion extending from a first one of the cusp segments to the tip, the second leg portion extending from a second one of the cusp segments to the tip, and further wherein the stent post frame is configured such that the first leg portion is free of connection to the second leg portion apart from the tip;

    a stent post frame cloth covering encompassing the rail;

    a base frame configured to support the cusp segments of the stent post frame, the base frame including a hub and a support wall extending transversely outwardly from the hub relative to the central longitudinal axis; and

    a valve leaflet assembly connected to the stent post frame and including a first leaflet clamped between the first one of the cusp segments and the support wall wherein a gap is defined between the first and second leg portions, and further wherein the first leaflet and a second leaflet of the valve leaflet assembly are within the gap and are clamped between the first and second leg portions;

    wherein the major axis of the rail is parallel to an engagement face of the support wall along the cusp segments wherein the engagement face is configured to continuously interface with the stent post frame along the cusp segments.
