Open Mitral Comissurotomy for Correction of Isolated Mitral Device

Abstract

Objective: To study the possibilities of open mitral commissurotomy for isolated mitral correction. Methods: A retrospective analysis was conducted on group included 225 patients with MP who were undergoing surgical treatment at the National Institute of Cardiovascular Surgery named after N.M. Amosov of the Academy of Medical Sciences of Ukraine from January 1, 1981 to January 1, 2008. All patients underwent correction of the bladder using OMC (146), as well as in combination with other plastic surgeries on the bladder (79 patients), incl. application of a support ring, suture commissuroplasty, resection of the posterior leaflet. Due to LA thrombosis, thrombectomy was performed in 71 (31.6%) patients. Correction of tricuspid defect in the form of annuloplication according to N.M. Amosov-De Vega was performed in 69 (30.7%) patients. Paraannular plication of the posterior wall of the left atrium using the Kawazoe technique was performed in 2 (0.9%) cases. Results: Of the 225 operated patients in the hospital stage (within 30 days after surgery), none died. Neurological (transient) complications were noted in 3 (1.3%) patients. Stay in the intensive care unit for 38-56 hours. Patients were discharged on average 9-11 days after surgery without clinically significant complications. Conclusion: Open mitral commissurotomy is an adequate method of surgical correction of urinary tract with a minimal risk of fatal complications. The technique is applicable both in isolation and in combination with commissuroplasty and the application of a support ring. The low probability of developing thromboembolic complications in patients with thrombosis of the left atrium allows us to recommend OMC as the operation of choice for massive thrombosis of the left atrium.
