DEVICE FOR PERFUSION OF PULMONARY ARTERY IN SURGICAL TREATMENT OF INFECTIOUS ENDOCARDITIS IN SETTING OF ARTIFICIAL BLOOD CIRCULATION

摘要

A device for perfusion of the pulmonary artery in the surgical treatment of the infectious endocarditis in the setting of the artificial blood circulation comprises the use of the apparatus of the artificial blood circulation. Prior to cardioplegic heart arrest, the cannula 8FR connected with the lateral branching of the arterial line of the artificial circulation circuit is inserted into the pulmonary artery. After the clamping of aorta, cardioplegia and removal of the infected valve, the trunk of the pulmonary artery is clamped. Then the lateral branching of the arterial line is opened for perfusion of the pulmonary artery with the arterial blood at the flow rate of 3-5 mL/kg/min. At the stage of sealing the heart cavities, the perfusion of the pulmonary artery is finished.
