Early And Long Term Outcomes Of Aortic Valve Surgery Combined Or Not With Cabg Surgery

Objective: The number of patients doing aortic valve surgery with or without CABG (Coronary Artery Bypass Graft) is increasing continuously in our country. The goal of this study is to evaluate the early and long-term results of aortic valve surgery alone or combined with CABG surgery. Methods: This is a retrospective and prospective study. We included the patients underwent aortic valve surgery (replacement or another procedure) with or without CABG from January 2007 to January 2013 . The population of 330 patients is divided into two groups: Group I included 81 patients combined surgery; Group II included 249 patients with isolated aortic valve surgery. In the early results we referred hospital mortality and perioperative complications. The follow-up time is from 2 to 73 months for 303 cases that were discharged from hospital. The long-term results were evaluated in terms of mean survival ,quality of life and prosthetic-related complications. Results: The hospital mortality was 3.6 % in general. The hospital mortality: group I is 4. 9% and group II is 3. 2 %. The difference is not statistically significant. Low cardiac output, conduction disturbances, stroke, pulmonary complications, renal complications, bleeding, atrial fibrillation, wound infections, ventricular arrhythmias are respectively14. 8% vs. 9. 6%, 3. 7% vs. 6. 9%, 3. 7% vs. 0. 4%, 9. 9 % vs. 2. 8%, 3. 7% vs. 1. 2%, 6. 3% vs. 2.0%, 14. 8 % vs. 19.7%, 11. 3% vs. 1. 6 %, 6. 2% vs. 5. 6 % respectively for the group I and II. The differences were statistically significant only for low cardiac output, stroke, pulmonary and wound complications. The long-term outcomes: overall mortality 3. 9%, bleeding 1. 9%, prosthetic endocarditis and thrombosis 1.3%. Endocarditis and thrombosis are more frequent in group I. During the follow-up survival was 93% and 96% respectively for group I and II, with no significant difference between groups. Conclusions: Simultaneous coronary artery by-pass with aortic valve increases slightly the operative mortality and perioperative complications. CABG surgery does not influence long?term results of aortic valve surgery.
