HOSPITAL OUTCOMES OF SURGICAL TREATMENT FOR FUNCTIONAL TRICUSPID VALVE INSUFFICIENCY DEPENDING ON THE CHOSEN METHOD OF SURGICAL TREATMENT

Purpose. To study and compare hospital outcomes of surgical treatment of functional (secondary) tricuspid insufficiency, depending on its etiology and on the chosen surgical method of its correction. Materials and methods. We performed clinical and hemodynamic evaluation of the outcomes of various methods of cardiac surgical treatment of patients with non-rheumatic tricuspid valve (TV) insufficiency (functional) in chronic forms of coronary artery disease (CAD), and delated cardiomyopathy (DCM). The study included 792 patients who during a period from 2011 to 2020 underwent correction of non-rheumatic TV insufficiency (functional): There were 642 participants with CAD, 150 participants with DCM. We assessed their echocardiographic parameters. Results. In the analyzed sample at the hospital stage, there was a significant decrease in the severity of tricuspid insufficiency after the performed TV repair. We found no influence of the etiology of TV lesion on the incidence of residual tricuspid insufficiency grade ≥ II at the hospital stage. In general, there was no effect of the TV plasty method (annuloplasty or suture techniques) on the incidence of residual tricuspid insufficiency gr
