    Abstract:
    The field of percutaneous valvular interventions is one of the most exciting and rapidly developing within interventional cardiology. Percutaneous pulmonary valve implantation (PPVI) represents the first in-human application of these techniques and is a nonsurgical option for treating right ventricular outflow tract/pulmonary trunk dysfunction. With the growing numbers of patients with right ventricle to pulmonary artery conduit dysfunction after repair of congenital heart disease, the importance of a technique with lower morbidity and mortality, good patient acceptance and efficacy, that is comparable to surgery, cannot be underestimated. Over the last 9 years, PPVI has become a feasible, safe and effective treatment for both conduit stenosis and regurgitation. Median follow-up data show good freedom from reoperation and recatheterization and demonstrate that PPVI can postpone open-heart surgery, thereby potentially reducing the number of operations that patients have to undergo within their lifetime. Complications seen after PPVI, in particular stent fractures, can require reintervention in some cases (second stent-in-stent PPVI); however, valve competency remains good, with significant regurgitation during follow-up only seen in the context of occasional endocarditis. Attempts are now being made to prolong the lifespan of the device by reducing the incidence of stent fractures. Further, meticulous patient selection must be maintained to ensure that hemodynamic results are optimized and the safety of the procedure remains high. Finally, new devices have to be developed that will allow for PPVI in dilated, distensible outflow tracts, to offer this nonsurgical treatment option to a larger patient population with congenital heart disease.
