Functional mitral regulation in ascending aortic aneurysm in patients undergoing aortic valve surgery

The Bentall-deBono operation is a complex surgical intervention on the aortic root. This operation is much more complicated than "standard" cardiac surgery procedures, and, accordingly, requires a longer duration of artificial blood circulation (IC) and better special equipment of the surgical and anesthesiological team. It is not surprising that according to the Russian Association of Cardiovascular Surgeons in Russia, no more than 1,000 such operations are performed annually in the entire country. Until now, there are discussions in the world about the tactics of surgical treatment for aortic and mitral valve lesions. Functional mitral regurgitation (MR) occurs in about a third of patients with aortic insufficiency (AN), and the choice of treatment tactics in such situations remains the prerogative of the operating surgeon. Most doctors correct MR only with severe mitral valve damage, and with moderate values of regurgitation, the combined operation is refused. This tactic is explained by the presence of a volume overload in the left parts of the heart, due to which a functional defect develops.
