Discussion to: Revascularization of coronary circulation in pulmonary atresia with intact ventricular septum and right ventricular-dependent coronary circulation

See Article page XXX. Revascularization of coronary circulation in pulmonary atresia with intact ventricular septum and right ventricular-dependent coronary circulationThe Journal of Thoracic and Cardiovascular SurgeryPreviewPulmonary atresia with intact ventricular septum (PA-IVS) and right ventricle-dependent coronary circulation (RVDCC) is a challenging condition that classically has mandated single-ventricle palliation without RV decompression. Some patients with evidence of coronary ischemia, ventricular dysfunction, or coronary ostial atresia require primary listing for transplantation to allow for survival out of early infancy. However, even with a transplant listing, the coronary circulation in this anatomy is very precarious and puts these patients at high risk of coronary compromise while awaiting transplantation.
