METHOD OF SURGICAL TREATMENT OF DISORDER OF BILUTARY AORTAL VALVE Russian patent published in 2017 - IPC A61F2/02 

FIELD: medicine.

SUBSTANCE: previously excised corneal lesions of the fibrous ring. Determining the diameter of the fibrous ring by selecting the meter included in the heart valve prosthesis kit "Perceval S". Then, the overlapping points of the three guide seams are determined by applying to the fibrous ring a means for marking the seams in the form of a ring whose diameter corresponds to the diameter of the fibrous ring and containing three marks along a circle at equal distances from one another and serving as a guide for selecting the overlapping points Guide seams. Then, the guide sutures are applied to the fibrous ring of the aortic valve at selected places from the ventricular side to the aorta, and the prosthesis is collected on the delivery device. Free ends of the filaments of the guide sutures from the ventricular side are passed through the corresponding fixed loops on the prosthetic heart valve "Perceval S". On the guide threads, the prosthesis is positioned at the level of the fibrous ring, removed from the delivery device. The lower part of the prosthesis is fixed with a double annular cuff to the fibrous ring, the prosthesis is squeezed by a balloon with a pressure of 4 at for 30 sec, controlling the correct arrangement of the double annular cuff of the heart valve prosthesis "Perceval S" in the fibrous ring. After that, the guide seams are removed.

EFFECT: method allows to increase the efficiency of surgical treatment of the defect of the bicuspid aortic valve, to shorten the operation time and shorten the time of the artificial circulation, to quickly restore the hemodynamics of the heart.
