SU1493254A1 - Method of valvuoplasty of aortal cardiac valve - Google Patents

Abstract

This invention relates to medicine. In order to reduce the number of postoperative complications associated with the eruption of sutures, by reducing the pressure drop across the valve during its operation, additional pouch suture over the valve leaflets along the arched ring is placed. The pressure drop across the valve in the operated patients was no more than 20 mm Hg.

Description

Of.) Bretepie refers to medicine, namely cardiovascular surgery.

The aim of the invention is to reduce the number of complications associated with the eruption of HJBa, by reducing the pressure drop across the valve during its operation.

CiH) co6 is carried out as follows.

Example. Patient S., 26 years old. During the examination, a rev.matic co mbini-aortic aortic defect with a prevalence of relative coronary insufficiency was revealed. The diagnosis was confirmed by clinical and instrumental methods of examination. Operated under artificial blood circulation and cold pharmacological cardioplegia. The operation revealed that the aortic valve with a measured fibrosis, regurgitation is due to prolapse of the right coronary valve and expansion of the aortic root. A sectorial resection of the right coronary sash was performed, followed by closing and the imposition of two pouch sutures. The main pouch suture was placed under the valves along the fibrous ring of the aortic valve. The ends of it are brought to the outer surface of the aorta and stitched through the gasket. Then an additional purse string was placed over the flaps along the articular aortic valve. The ends of it are brought to the outer surface of the aorta and also stitched through the gasket. After that, the aortic incision is sutured. Restored heart activity. Introduce catheters in ao) tu and in, 1st ventricle. A sensor of the flow meter is superimposed on the aorta and, under the control of the differential, is given, 1 and regurgitation on the valve) the 1st dose of the ociioBHoii and D1) is tightened, and the pouch lining is the required value. Regurgnection decreased from 65 to 6%, while the pressure drop did not exceed. 20 mm Hg Art. The postoperative period was uneventful.

According to the described method, 9 surgical interventions were performed in patients with rheumatic combined malformations ;; - aortic valve with suppression of insufficiency.

All patients managed to achieve quite satisfactory recovery of central hemodynamic parameters (pressure drop not exceeding 20 mm Hg. Art.) And significantly reduce the degree of perypi H-tation (not more than 5% of the shock release). Complications associated with the features of the proposed Surgery techniques: No corrective correction of aortic insufficiency of the 1st valve is noted.
