Abstract: Изобретение относится к медицине, а именно к сердечно-сосудистой хирургии. Пликационный шов начинают со свободного края пораженного сегмента задней створки и выполняют его только первой нитью. При этом первой нитью берут в складку пролабирующий или разорванный сегмент створки и накладывают шов до фиброзного кольца клапана. После этого имплантируют жесткое опорное кольцо и проводят гидравлические пробы с оценкой результата пластики. При состоятельности клапана второй нитью двойного обвивного шва выполняют стежки, одинаковые со стежками, выполненными первой нитью. При появлении или сохранении протечек клапана в реконструированном участке второй нитью двойного обвивного шва накладывают стежки, отличающиеся от стежков, выполненных первой нитью. Затем вторую нить также проводят до фиброзного кольца клапана и её конец связывают с концом первой нити. Способ позволяет обеспечить возможность проведения «возвратной», безрезекционной, контролируемой пластики митрального клапана, позволяющей исправлять протечки, возникающие по ходу этапов реконструкции, без необходимости снятия ранее наложенных двойного обвивного пликационного шва и/или опорного кольца за счет изменения последовательности этапов операции наложения на зону разрыва или пролапса задней створки двойного обвивного шва. 2 пр., 5 ил.
