Abstract:

Introduction: The purpose of this study is to provide early and long-term results after the replacement of the mitral cover we apply in the treatment of the rheumatism mitral cover disease, which is etiologically common in our clinic. Patients and Method: Between July 2008 and December 2017, all incidents of mitral cover replacement in our clinic were reverse examinations. The study included the phenomena of mitral cover replacement on the ground of romantic etiology. The outcomes that were primarily considered were postoperative mortality rates, late survival rates, and late mortality factors. 88 patients were involved in the study. Four (4.5%) patients experienced mortality within the first 30 days. In the preoperative period with AF rhythm and simultaneous arithmic surgery applied 19 (21%). 6) 11 (12.5%) of the patient returned to sinus rhythm. The five-year survival rate of all patients was 77.9%. According to mitral thickness, insufficiency and combined mitral thickness and insufficiency pathology, the five-year survival rates were 72.6%, 81.8% and 86.7% respectively, and there was no statistical difference between the groups (Log Rank, p= 0.63). Independent predictors affecting long-term mortality were presence of preoperative chronic kidney failure (HR: 33.4, 95% CI: 4.1-272.3, p= 0.001) and cardiopulmonary hypertension time (HR: 1.05, 95% CI: 1.02-1.08, p< 0.001) (Cox regression). The result: Romatism mitral cover disease remains up to date in our country due to rural and cross-border migration. For the prevention of recurrence, the provision of an effective cover orifis area and the reduction of the risk of narrowness in the left ventricular output path, the cover replacement results are quite good and a better option. It is also necessary to take measures in the presence of preoperative chronic renal insufficiency in terms of the long-term survival effect and to avoid prolonged cardiopulmonary bacteria during the operation.
