ABSTRACT

According to the 2013 WHO survey, the world’s leading cause of death is a coronary heart disease which is accounted for 12.9%. Bypass surgery by grafting Artery mammaria interna to the left anterior descending coronary artery is more clinically significant and has long become an international standard. Aim: To study the outcomes in patients who undergone a bypass surgery ofgrafting the Artery mammaria interna to the left anterior descending coronary artery in an open heart surgery. In 2014 in the case-control study conducted at the Shastin 3rd National Central Hospital, 8 patients who undergone a bypass surgery of grafing Artery mammaria internasinistra to the left anterior descending coronary artery were selected for a case group and 8 patients with bypass grafting of a superficial vein of the leg to the coronary artery were selected as a control group. Related diseases, heart function, type of grafting performed, and post-operative complications were studied. The successful bypass surgeries of grafting the Artery mammaria interna sinistra to the left anterior descending coronary artery without complications in the case group in 2014 has demonstrated that the Mongolian cardiosurgical team was able to successfully and fully introduce this innovative approach that has become an international standard of coronary artery surgery. The introduction of this method enables to eliminate angina pectoris symptoms in patients, restore and improve heart contractions, reduce the chances of a repeat heart attack, and thus, to improve the patient’s ability to live and work normally.
