METHOD FOR REINFORCING SINUS OF VALSALVA WALL AND IMPLANTING AORTAL VALVE PROSTHESIS IN WHEAT OPERATION Russian patent published in 2014 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to cardiovascular surgery . An aortic opening is exposed transversally along the line of a sinotubular ridge. That is followed by a supracoronary aneurism resection of a descending aorta. Aortic valve cusps are not excised, though used to reinforce sinus of Valsalva walls. To this effect, lined U-sutures in the right and left coronary sinuses of Valsalva with a needle pricked in the base of the aortic valve cusp from the opening of the sinuses of Valsalva and pricked out 1-2 mm below the cusp bottom from the back side into an opening of a left ventricular outflow tract. The U-suture linings are left from the side of the coronary sinuses of Valsalva. One lined U-suture is formed in a subcommisural triangle between the right and left coronary cusps. A border of the non-coronary cusp is sutured down to the aorta from the inside to the non-coronary sinus of Valsalva wall along the line of the sinotubular ridge with using a continuous blanket suture. The coronary cusps of the aortic valve is sutured down to aorta from the inside to the coronary sinuses of Valsalva wall along an arched line immediately below coronary arteries mouths with the continuous blanket suture. The linings of the previous U-sutures are found between the coronary sinuses of Valsalva wall and the coronary cusps. The centre of the aortic valve cusps is fixed with one or two U-sutures to an underlying sinuses of Valsalva wall. An aortal valve prosthesis is implanted with sutures pre-formed in the coronary sinuses of Valsalva and the subcommisural triangle between the right and left coronary cusps. Separate interrupted U-sutures are formed along the contact line of an aortal valve prosthesis cuff and the pre-reinforced non-coronary sinus of Valsalva with the needle pricked in outside the aorta, and pricked out in the opening through the aortal valve prosthesis cuff.

EFFECT: method enables reinforcing the sinuses of Valsalva using the proper aortic valve cusps and implanting the aortal valve prosthesis 1-2 sizes larger than anatomical one that makes it possible to prevent postoperative sinus of Valsalva aneurism, and aortal valve prosthesis and patient inconsistency syndrome.
