[PLASTY OF THE INTERVENTRICLE SEPTUM DEFECT, USING A PATCH WITH A VALVE IN PATIENTS, SUFFERING HIGH PULMONARY...

Right ventricle insufficiency due to pulmonary hypertensive crysis or persisting pulmonary arterial hypertension (PAH) in patients after the interventricle septum defect (IVSD) closure with the heightened resistance of pulmonary arteries (RPA) constitutes an actual problem and associates with a high risk for a life-threatening complications and high lethality. Experience of the IVSD plasty conduction in a patient with high PAH, using a patch with a valve for right ventricle decompression while pulmonary hypertensive crysis in early postoperative period and nonreversible PAH in the remote period of observation, was presented. In the clinic 38 children were operated on for big IVSD, complicated by high PAH and heightened RPA, using a patch with a valve in 1996 - 2014 yrs. Hospital lethality have constituted 2.6%. Postoperatively a pressure in pulmonary artery (PA) have lowered trustworthy from (93.4 ? 14.9) to (49.2 ? 22.9) mm Hg. In a remote period of observation all the patients were alive. In 6 (16.2%) patients in terms from 4 mo to 18 yrs postoperatively a PAH have occurred, a pressure in PA was by 50% higher, than a systemic one. The IVSD plasty in patients with high PAH and heightened RPA may appear successful if a patch with a valve are applied.
