  • This study examines the outcomes of transcatheter closure in patients with Coronary Artery Fistulas (CAFs), specifically comparing those with aneurysms to those without.
  • It included 104 patients, revealing that those with aneurysms were significantly younger and more likely to have heart murmurs, while larger fistula diameters and the presence of coronary-cameral fistulas were identified as risk factors for aneurysms.
  • Ultimately, the study found that closure outcomes were similar for both groups, but post-closure thrombosis was more common in patients with aneurysms.

Transcatheter pulmonary valve replacement (TPVR), also known as percutaneous pulmonary valve implantation, refers to a minimally invasive technique that replaces the pulmonary valve by delivering an artificial pulmonary prosthesis through a catheter into the diseased pulmonary valve under the guidance of X-ray and/or echocardiogram while the heart is still beating not arrested. In recent years, TPVR has achieved remarkable progress in device development, evidence-based medicine proof and clinical experience. To update the knowledge of TPVR in a timely fashion, and according to the latest research and further facilitate the standardized and healthy development of TPVR in Asia, we have updated this consensus statement.
