EU PAS Register NumberEUPAS5064
Official titleEuropean Clinical Study for the Application of Regenerative Heart Valves
Study title acronymESPOIR
Study typeActive surveillance
Brief description of the studyBoth acquired and congenital heart disease can require heart valve replacement. Currently available heart valve substitutes are, however, not ideal as they require anticoagulation, with the risk of bleeding when manufactured from non-organic material, or they degenerate when derived from animals (xenografts) or human tissue donors (homografts), leading to the need for frequent reoperation, especially in children and young adults. An ideal heart valve substitute would have the potential to grow even when implanted in paediatric patients. ESPOIR PV hosts the power to regenerate. The purpose of this investigation is to evaluate decellularized human pulmonary valve, Espoir PV (“ESPOIR PV”) for pulmonary valve replacement rates in comparison to current valve substitutes within a large prospective multicentre surveillance at 8 leading European Centres for Congenital Cardiothoracic Surgery regarding re-operation and re-intervention, hemodynamic performance, growth potential and long term durability. Primary safety endpoints: Rate of cardiovascular adverse reactions, leading to e.g. re-operation, catheter based interventions. Secondary safety data: Collection of medical data to assess the process of tissue vigilance. Collection of medical history to support the presence/absence of adverse events, e.g. infections, arrhythmia. Primary efficacy endpoint: Freedom from valve dysfunction leading to re-intervention or explanation at end of the Surveillance. Key secondary efficacy endpoint: Diameters of ESPOIR PV at end of the Surveillance in comparison to diameters at implantation, transvalvular gradients, valve competence assessed by non-invasive imaging tools such as echocardiography or cardiac magnetic resonance imaging.
