“SURGICAL FORMULA” FOR CORONARY BYPASS: NEW OPPORTUNITIES FOR COMPUTER DATA PROCESSING AND PERSONALIZED ASSESSMENT OF TREATMENT RESULTS

Abstract

Objective: To develop a “surgical formula” for CABG and evaluate the results of its application for the taxonomy of direct MR options Methods: Four hundred fifty-two internal mammary artery-aortocoronary bypass (IMA-ACB) using two and three shunts (conduits) were performed from January 2020 to December 2023 at A.O. Makhachev Center for Cardiology and Cardiovascular Surgery, Makhachkala, Dagestan. Off-pump surgeries were performed in 315 patients, while 137 patients underwent on-pump CABG. The MR index was 3.5. Every IMA-ACB option had specifications indicating the particular donor artery, graft, and recipient coronary artery (CA). A “surgical formula” comprising the above specifications was developed for every MR surgery option Results: There was no in-hospital mortality among the patients enrolled in the study. According to intraoperative monitoring, the incidence of shunt dysfunction was 0.4%. Overall, 32 “surgical formulas” were developed for all types of operations performed in patients enrolled in this study. Conclusion: Introducing “surgical formulas” in the operation records at the cardiac surgery departments facilitates the systematization and classification of CABG options
