Abstract

Our review is intended to provide readers with an overview of disease processes involving the pulmonic valve, highlighting recent outcome studies and guideline-based recommendations; with focus on the two most common interventions for treating pulmonic valve disease, balloon pulmonary valvuloplasty and pulmonic valve replacement.The main long-term sequelae of balloon pulmonary valvuloplasty, the gold standard treatment for pulmonic stenosis, remain pulmonic regurgitation and valvular restenosis. The balloon:annulus ratio is a major contributor to both, with high ratios resulting in greater degrees of regurgitation, and small ratios increasing risk for restenosis. Recent studies suggest that a ratio of approximately 1.2 may provide the most optimal results. Pulmonic valve replacement is currently the procedure of choice for patients with severe pulmonic regurgitation and hemodynamic sequelae or symptoms, yet it remains uncertain how it impacts long-term survival. Transcatheter pulmonic valve replacement is a rapidly evolving field and recent outcome studies suggest short and mid-term results at least equivalent to surgery. The Melody valve® was FDA approved for failing pulmonary surgical conduits in 2010 and for failing bioprosthetic surgical pulmonic valves in 2017 and has been extensively studied, whereas the Sapien XT valve®, offering larger diameters, was approved for failing pulmonary conduits in 2016 and has been less extensively studied. Patients with pulmonic valve disease deserve lifelong surveillance for complications. Transcatheter pulmonic valve replacement is a novel and attractive therapeutic option, but is currently only FDA approved for patients with failing pulmonary conduits or dysfunctional surgical bioprosthetic valves. New advances will undoubtedly increase the utilization of this rapidly expanding technology.

Dr. Richard Krasuski is Director of the Adult Congenital Heart Center at Duke University Medical Center, the Director of Hemodynamic Research, and the Medical Director of the CTEPH Program. He is considered a thought leader in the fields of pulmonary hypertension and congenital heart disease. His research focus is in epidemiologic and clinical studies involving patients with pulmonary hypertension and patients with congenital heart disease. He is involved in multiple multicenter studies through the Alliance for Adult Research in Congenital Cardiology (AARCC). He has also helped to develop multiple research databases in these patient populations. He is Co-PI in the upcoming EPIPHANY Study examining the impact of medical and transcatheter interventions on RV-PA coupling in patients with chronic thromboembolic pulmonary hypertension. Over his career he has mentored over 80 students, residents and fellows and has published over 300 peer reviewed publications, book chapters and meeting abstracts. He is also the Chief Editor of Advances in Pulmonary Hypertension and on the editorial boards of several leading medical journals.
