FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to cardiosurgery. In cyanotic congenital heart diseases (CHD) combined with hypoplasia of the pulmonary artery system in older patients, palliative infundibulectomy is performed without closing the defect of the interventricular septum by accessing the right atrium. That is ensured by opening the right atrium along the atrioventricular sulcus. Septal and parietal legs of the hypertrophied tapered partition are resected to the passage size.
EFFECT: method enables preserving cardiac myocardial integrity by avoiding the need for a right ventricular incision, avoiding hypervolemia of the pulmonary circulation.
