Prognostic value of anatomical dominance of coronary circulation in patients with surgical myocardial revascularization.

Omerbasic E, Hasanovic A, Omerbasic A, Pandur S - Med Arch (2015)

Bottom Line: Inability of revascularization of the r. interventricularis posterior (RIVP) was statistically significantly higher in case of left dominance 9/21 (42.9%), compared to the right 16/79 (20.3%), p=0.033.Lethal outcome was more common in case of left dominance in relation to the right (9.4% vs 0.9%).The incidence of surgical complications, respiratory, neurological and renal complications was not significantly different between groups, while the length of hospital stay was significantly higher in the group of patients with left dominance, p = 0.003.

ABSTRACT

Introduction: This study evaluated the frequency of domination of the coronary arteries types in patients treated by surgical myocardial revascularization. The aim of the study was to determine whether the left coronary circulation dominance is a prognostic factor for poorer outcome in patients undergoing coronary artery bypass surgery.

Material and methods: A total sample consisted of 100 patients with coronary artery disease that were treated with coronary artery bypass grafting at the Clinic for Cardiac Surgery, Clinical Center of the University of Sarajevo. To all patients on the basis of preoperative coronary angiography was determined the dominance of the coronary arteries. Patients included in the study were divided into two groups, with the left and right with coronary dominance.

Results: Left coronary dominance in a sample of patients was present in 21/100 (21%), right in 69/100 (69%) and balanced in 10/100 (10%) cases. Female gender was significantly more frequent in patients with left coronary dominance and proved to be a stronger predictor of poorer outcome, especially in combination with left main stenosis of the left coronary artery and left coronary dominance. Inability of revascularization of the r. interventricularis posterior (RIVP) was statistically significantly higher in case of left dominance 9/21 (42.9%), compared to the right 16/79 (20.3%), p=0.033. Lethal outcome was more common in case of left dominance in relation to the right (9.4% vs 0.9%). The incidence of surgical complications, respiratory, neurological and renal complications was not significantly different between groups, while the length of hospital stay was significantly higher in the group of patients with left dominance, p = 0.003.

Conclusion: Left coronary dominance is an important risk factor for patients undergoing surgical myocardial revascularization.

Mentions: Analysis of 100 patients coronary angiograms who were surgically treated in our institution, showed the left coronary dominance type was present in 21/100 (21%) of patients, mixed type with 10/100 (10%) patients, while the largest number 69/100 patients (69%) had the right type of coronary dominance (Figure 1 and Figure 2).
