METHOD FOR PRESSURE TEST IN MITRAL VALVULAR DISEASE

摘要

FIELD: medicine.SUBSTANCE: pressure test in the mitral valvular disease requires introducing a sterile solution through a catheter into a left ventricular cavity. The catheter previously used to settle a cardioplegic cannula is brought through an ascending aortic wall without involving the valve cusps. What is used is a catheter of the diameter of 2 mm or a similar tube. The sterile solution is presented by 0.9% normal saline at approximate temperature 5°C. The solution is introduced at a pressure equal to the left ventricular pressure of 120-140 torr. The solution is infused, and the left ventricle is filled continuously with determining a degree of regurgitation and locating a cusp separation.EFFECT: method enables the pressure test in the mitral valvular disease, avoiding the foaming of the solution used for the purpose of the hydraulic test, enables suturing the mitral cusps ensured by the continuous solution infusion and left ventricular filling.3 cl, 1 ex
