Abstract: Изобретение относится к медицине, а именно к сердечно-сосудистой хирургии. Окружность ФК условно делят на три полуокружности и соответственно на девять сегментов: A1, А2, A3 - относящихся к передней полуокружности, P1, Р2, Р3 - относящиеся к задней полуокружности, и S1, S2, S3 - относящие к септальной полуокружности. При этом А2, Р2, и S2 являются серединой основания каждой створки. Швы накладывают на сегменты S2, Р2 и А2, а также на медиальную половину сегментов А1, A3, Р1, Р3, S1, S3. Комиссуральные зоны ФК оставляют свободными от наложения швов. Способ позволяет добиться снижения числа осложнений, обусловленных отсутствием необходимости прошивания ФК по всему периметру, что позволяет существенно снизить риск развития острого коронарного события, возникающего в результате захвата в шов коронарной артерии или ее перегиба, кроме того, уменьшается риск возникновения осложнений, обусловленных отсутствием необходимости прошивания ФК в области локализации проводящих путей, что позволяет существенно снизить риск развития нарушений ритма и проводимости в послеоперационном периоде, также исключена возможность чрезмерного сужения атриовентрикулярного отверстия за счет изменения концентрического размера расстояния, изменяется форма ФК ТК без значимого изменения его площади, происходит сближение створок, что обеспечивает улучшение их кооптации. 2 ил.
