Abstract [eng] The review of scientific work presented for habilitation procedure summarizes the experience of redo operations of patients after replacement of heart valves accumulated at the Heart Surgery Centre of Vilnius University Clinic of Angiology and Cardiology. The efficacy of low thrombogenicity valve prostheses was evaluated. It was found out that the mortality rate of very severely ill patients with infected did not decrease; however the larger number of patients in functional class III were being operated during the period of recent years and the results of these operations were excellent. The rate of redo tricuspid valve operations had decreased effectively because of more radical surgery treatment of this valve during the primary operation. The operation of replacement of old ball prosthesis has been validated. The new incisions of the heart were introduced as well as new methods of performance of chest box incisions and pharmacologic and non-pharmacologic methods of perioperative hemostasis; the methods mentioned above effectively reduced the risk of bleeding. The original method of the left ventricle venting via separate thoracotomy incision enabled to reduce postoperative heart failure. This work is based on the results of operations performed in cooperation with co-workers. As a chief of the department where the patients with pathology of heart valves are treated, I am performing more than a half of redo operations. The scientific presentations concerning the results of redo operations were presented at Lithuanian, European and world congresses and meetings.
