1. A prosthetic heart valve, comprising:
a self-expanding stent having an inflow end, an outflow end, a luminal surface defining a lumen through the stent, and an abluminal surface opposite the luminal surface, the stent having an expanded condition and a collapsed condition, the stent being formed of cells, the cells including a proximal-most row of diamond-shaped cells at the inflow end of the stent;
a plurality of prosthetic leaflets disposed within the lumen of the stent; and
a cuff assembly including a first cuff portion and a second cuff portion,
wherein the first cuff portion is positioned on the luminal surface of the stent in both the expanded condition of the stent and the collapsed condition of the stent;
wherein the second cuff portion is positioned on the abluminal surface of the stent in a deployed configuration of the second cuff portion so that the second cuff covers at least a portion of the proximal-most row of cells, the second cuff portion having a terminal edge that is positioned a spaced distance from the inflow end of the stent and points toward the outflow end of the stent in the deployed configuration of the second cuff portion;
wherein in the deployed condition of the second cuff portion, an entirety of the terminal edge is not directly coupled to the stent so that a continuous pocket is formed between the second cuff portion and the abluminal surface of the stent; and
wherein the first cuff portion is positioned between the plurality of prosthetic leaflets and the stent.
