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

Abstract

Patients with left main coronary artery stenosis often have complex coexisting coronary artery disease. Surgical revascularization is still the standard modality of treatment. 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. From 2006 to 2015, a total of 46 patients (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 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. 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. 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.
