Direct Results PTMC of Rheumatic Mitral Stenosis
Analysis of results of percutaneous transluminal mitral commisurotomy (PTMC) by Inoue technique in 310 patients with stenosis of the mitral orifice (MO) at the age of 10 to 69 years, in mean 49,4 ± 9,1 years. In 305 (98,4%) patients successfully completed the PTMC. In 5 (1.6%) patients PTMC failed, 3 of them atrial septum puncture was unsuccessful, and 2 - the balloon catheter could not pass through critically mitral stenosis. Fatal outcome occurred in 1 (0.3%) case patient with critical mitral stenosis, she was operated on under general anesthesia in critical condition with pulmonary edema. MO was opened from 0,6 см2 to 1,8 cm2, in spite of then pulmonary edema could not be managed. All other patient after PTMC the area of mitral orifice increased by 2.5-fold (from 0,85 ± 0,17 to 2,16 ± ± 0,76 cm2 (p <0,001), transmittal gradient decreased from 26,9 ± 2,95 to 8,9 ± 0,6 mm Hg (p < 0,0001), maximum pressure in the LA was decreased from 40,29 ± 6,01 mm Hg.to 21,43 ± 3,83 mm Hg (p < 0,05) in PA - 49,7 ± 10,9 to 29,7±8,2mmHg(p<0,05). PTMC of Inoue technique is a highly effective method of treatment, of mitral stenosis it has low rate complications and mortality, and can suggested as alternative to surgical treatment.
