1. A method of deploying a prosthetic heart valve, the method comprising:
advancing, via a femoral vein and an inferior vena cava, the prosthetic heart valve toward a native tricuspid valve while the prosthetic heart valve is releasably coupled to a prosthetic heart valve deployment system and diametrically constrained in a low-profile delivery configuration within a first lumen of an outer steerable sheath catheter, wherein the prosthetic heart valve comprises:
a main body comprising an inflow end portion and an outflow end portion; and
one or more anterior flaps extending from the outflow end portion;
with a distal end portion of the outer steerable sheath catheter in a right atrium, deflecting the distal end portion of the outer steerable sheath catheter toward the native tricuspid valve; and
expressing the prosthetic heart valve from the outer steerable sheath catheter while maintaining a position of the outer steerable sheath catheter substantially stationary, wherein the inflow end portion of the prosthetic heart valve is expressed only after an entirety of the outflow end portion has been expressed, and wherein the one or more anterior flaps extend into a right ventricular outflow tract (RVOT) as a result of the expressing of the prosthetic heart valve from the outer sheath, and
wherein the prosthetic heart valve deployment system comprises:
a middle deflectable catheter slidably disposed in the first lumen and defining a second lumen, the middle deflectable catheter comprising a selectively deflectable distal end portion; and
an inner control catheter slidably disposed in the second lumen and including one or more control wires that are releasably coupled with the prosthetic heart valve.
