Transcatheter Pulmonary Valve Replacement: Current Status and Future Potentials.

Although established, transcatheter pulmonary valve replacement is in its infancy compared with surgical pulmonary valve replacement. Extended clinical experience and follow-up have identified new challenges; however, careful evaluation of data through clinical trials has facilitated effective evolution of responses to these challenges. The limited patient population has resulted in less interest in new valve design, but having been the older sibling to transcatheter aortic valve replacement, transcatheter pulmonary valve replacement is likely to benefit in the future from design modifications to the more popular and commercially viable transcatheter aortic valve revolution. Improving valve longevity and applying the technology to native outflow tracts remain the short-to-medium term goals.
