ABSTRACT
This study examined the results of surgical trivalve of 44 patients with trivalve heart defect. In all the patients the heart defect was combined with two and more complicating factors: advanced III-degree calcinosis of the valves, cardiomegaly, cardiac fibrillation, left atrium thrombosis, high pulmonary hypertension. In 20 patients the operative intervention on the heart was repeated. The analysis of the results allowed to recommend some surgical techniques which allowed to decrease surgical traumatism in patients with complicated trivalve heart defect. Low traumatism was possible because of incomplete removal of the calcium masses extending on the fibrotic ring and outside, use of two-row counter U-suture on linings for the prosthesis fixing, transdoubleatrial approach without isolation of the heart from the adhesions in dense pericardial obliteration, correction even insignificant trivalve heart defect or relative valve incompetence.
