1. A prosthetic heart valve comprising:
a main body and an anterior flap, the main body comprising an inflow end portion and an outflow end portion; and
an occluder extending between the inflow end and outflow end portions and defining a longitudinal axis, the occluder comprising valve leaflets attached to the main body in an arrangement that: (i) allows blood flow through the occluder in a direction from the inflow end portion toward the outflow end portion and (ii) prevents blood flow through the occluder in a direction from the outflow end portion toward the inflow end portion, the occluder having a circular cross-sectional shape and a radius,
wherein the anterior flap comprises a first portion, a mid-body portion, and a terminal end portion that extends from the mid-body portion,
wherein the first portion is attached to the outflow end portion of the main body and extends substantially perpendicularly from the outflow end portion of the main body to the mid-body portion,
wherein the mid-body portion is bent at an angle that directs the terminal end portion of the anterior flap partially toward the inflow end portion, and
wherein a tip of the terminal end portion of the anterior flap is spaced apart from the main body by a distance greater than the radius.
