Right heart transcatheter valve therapies - a review of prostheses for the pulmonary and tricuspid positions.

Minimally invasive, catheter-based treatment of valvular dysfunction has become an integral part of clinical routine. As left heart valvular disease is much more common and thus commercially of interest, transcatheter solutions for the treatment of aortic and mitral valvular defects were the first to become broadly clinically available, while even today options for the right heart valve are rare. This review looks at innovative attempts at developing effective transcatheter heart valve prostheses for the pulmonary and tricuspid heart valves, details their experience and highlights those that have made their way to application in humans.
