Purposes of this study were to evaluate the performance of our coronary reoperations and to determine the risk factors affecting mortality and morbidity according to preoperative, perioperative, and postoperative early and mid-term follow-up results.

Methods:

A retrospective analysis of preoperative, perioperative, and postoperative early and mid-term follow-up data of 40 patients who underwent reoperative coronary artery bypass grafting via moderately hypothemic cardiopulmonary bypass in the Cardiovascular Surgery Department of Ege University between 1994 and 1999, was performed. Follow-up data after the discharge of these patients were obtained via monthly periodical examinations in first 6 months, and after then via telephone interviews.

Results: As two occured in perioperative, and one in postoperative periods overall mortality was 3 (7.5%) patients. Cardiac problems were observed in 12 of overall 16 complicated patients. The improvement in functional capacity of surviving 37 patients was perfect in 31 ± 19.36 months of follow-up. Preoperative factors associated with increased in-hospital mortality and morbidity were diabetes, hypertension, hypercholesterolemia, ejection fraction (LVEF) of < %50, and previous myocardial infarction (MI). Besides these factors, obesity, chronic obstructive pulmonary disease (COPD), female sex, and older age were also associated with increased morbidity.

Conclusions:

The mortality and morbidity rates of our coronary reoperations were low as well as postoperative symptomatic improvement and survival rates were satisfactory. Hypercholesterolemia, hypertension, diabetes, obesity, female sex, COPD, older age, previous MI, and low LVEF were appeared as significant risk factors in coronary reoperations.
