摘要：
A prosthetic heart valve having an inflow end, an outflow end and a longitudinal axis extending from the inflow end to the outflow end includes a collapsible and expandable stent including a plurality of cells arranged in at least one row extending around a circumference of the stent. The stent further includes at least one engaging arm joined to one of the cells adjacent the outflow end and having a free end extending toward the inflow end, the engaging arm being movable between a loaded condition in which the engaging arm is oriented substantially parallel with the longitudinal axis of the stent, a partially-released condition in which the engaging arm forms a first angle with the longitudinal axis of the stent, and a fully-released condition in which the engaging arm forms a second angle with the longitudinal axis of the stent, the first angle being larger than the second angle.
