Transcatheter pulmonary valve implantation. Clinical treatment protocol and accreditation requirements for centers and interventionists in Brazil

Abstract

Transcatheter pulmonary valve implantation (TPVI) has evolved significantly since its introduction in the early 2000s. Currently, this technique is a safe and effective option for the treatment of severe valve dysfunction (stenosis and/or regurgitation) in bioprostheses or surgical conduits in pulmonary position, in several centers worldwide. In Brazil, the initial results with this procedure in reference centers were similar to those observed in the overall experience. TPVI was proven to be feasible, safe, and effective in trained hands in Brazil. However, prior to the widespread application of this technique to other centers in this country, it was necessary to establish some criteria for patient selection, implantation technique, and clinical follow-up, as well as for the training and accreditation of new interventionists and centers. The guidelines described here were determined by a group of experts with well-known experience in congenital heart disease and TPVI, and were referred to the Conselho Federal de Medicina (CFM, portuguese for Federal Council of Medicine). Representatives of the different medical societies were involved in the creation of this document, including the Sociedade Brasileira de Cardiologia (SBC, portuguese for Brazilian Society of Cardiology), the Sociedade Brasileira de Hemodinâmica e Cardiologia Invasiva (SBHCI, portuguese for Brazilian Society of Hemodynamics and Invasive Cardiology), and the Sociedade Brasileira de Cirurgia Cardiovascular (SBCCV, portuguese for Brazilian Society of Cardiovascular Surgery). The authors believe that strict adherence to the recommendations contained in this official document is crucial for patient safety and for optimal results to be achieved in both the short and long term. Once consolidated in Brazil, TPVI will open doors for the introduction of new valve therapies in congenital cardiopathies.
