ABSTRACT: Background: The aim of this study was to evaluate the impact of additional coronary revascularization on the early results in patients submitted to valve surgery. Patients and Methods: A retrospective review of the cardiac surgical database between January 2000 and December 2018 was performed. A total of 1667 patients were included and divided into two groups: Group A isolated valve surgery (IVS n = 1608) and Group B with valve surgery combined to coronary artery bypass grafting (VS + CABG n = 59). Demographic, operative data and postoperative outcomes were compared between groups. Results: Patients with combined procedure were older than patients who underwent isolated valvular surgery (64.9 ± 9.2 years vs 44.4 ± 13.1 years; p = 0.0001) and there was a higher proportion of diabetics (40.7% vs 6.6%; p = 0.0001). The 30 days mortality rate in the combined procedure group was 18.6% versus 6.2% in isolated valve surgery (p = 0.001). Also post-operative complications were more frequent than for patients who underwent IVS. Additionally we noted a high prevalence of coronary artery risk factors in patients with combined procedures. Conclusion: Surgical mortality and morbidity of coexisting coronary and heart valve disease were substantially higher than IVS. More efforts in medical management may reduce the incidence of adverse outcomes.
