A system for treating abnormalities of the right ventricular outflow tract includes a prosthetic valve device having a barrier material contacting at least a portion of the outer surface of the valve device. One embodiment of the invention includes a barrier member attached to the exterior surface of the valve device. Another embodiment includes a barrier material that is injected within the vascular system. Yet another embodiment of the invention includes a method for replacing a pulmonary valve that includes forming a barrier around the outer surface of a replacement valve and preventing blood flow around the replacement valve.
