Surgical Revascularization of Coexistent Significant Left Main and Right Coronary Artery Stenosis: A Single Center Experience

Abstract

<strong>Background:</strong> Patients with left main coronary artery stenosis often have complex coexisting coronary artery disease. Surgical revascularization is still the standard modality of treatment.<br />Objective: To present our experience in surgical revascularization for patients with stenosis of both left main and right coronary artery and evaluate the impact of the latter on the outcome of surgery.<br /><strong>Methods:</strong> From 2006 to 2015, a total of 46 patients <br />(38 male and 8 female, mean age 56.3 years) underwent coronary artery bypass grafts for stenosis of both left main and right coronary artery. Risk factors for coronary artery disease were identified in 93.4%. EuroSCORE II was <br />2.2 ± 4.29. All were operated on pump with mean grafts 3.3 ± 0.8.1 per patient. Intraaortic balloon was inserted in 11 patients. <br /><strong>Results:</strong> Early postoperative mortality was 8.7%. Regarding complications, we reported bleeding in 6 patients, sternal wound infection in 5, renal impairment in 5, respiratory complications in 2, and myocardial infarction in 4.<br /><strong>Conclusion:</strong> Surgical revascularization for patients with stenosis of both left main and right coronary artery has a higher morbidity and mortality when compared to results of surgery for isolated left main disease.
