Abstract:
Background: Despite the superior hemodynamic performance of internal thoracic arteries, total arterial revascularization with exclusive bilateral internal thoracic arteries (BITA) is less frequently used especially in specific subsets of patients, including females. We report our experience with total arterial revascularization with exclusive BITA regardless of sex and analyze the impact of female sex on the early and midterm outcomes. Methods: Total arterial revascularization with exclusive BITA was performed with equal frequency in females (79/99, 80%) and males (392/477, 82%; P = .68) undergoing isolated CABG for 3-vessel disease. Pre, intra and postoperative data were compared between these two groups. Results: Complete revascularization was achieved in 77% of females and 72% of males (P = .08). Early mortality did not differ between the groups (6.3% versus 4.6%, P = .7). The incidence of re-sternotomy for bleeding, postoperative stroke, myocardial infarction, new onset atrial fibrillation, and hemofiltration for renal failure did not differ between the two groups. However, there were significantly more wound revision for combined superficial and deep sternal wound infection in females (26.5% versus 5.1%, P = .0001). Nevertheless, midterm survival, freedom from repeat revascularization, myocardial infarction, stroke, and major adverse cardiovascular and cerebral events at five years were very good and compared favorably between females and males. Conclusions: Our findings suggest that total arterial myocardial revascularization with exclusive internal thoracic arteries in females carries the same midterm benefits as in males. Early outcomes are comparable except for a higher incidence of wound revision for combined superficial and deep sternal wound infections in females compared to males. Benefits of bilateral internal thoracic artery grafting in females should be weighed against increased risk of early wound revision.
