Does immediate coronary artery bypass grafting and aortic repair improve survival in patients with acute type A aortic dissection and coronary malperfusion?
Immediate coronary artery bypass grafting concomitant with aortic repair is a feasible approach for acute type A aortic dissection with coronary malperfusion, with a hospital mortality rate of 21.4%.
BACKGROUND: Acute aortic dissection coexisting with coronary malperfusion is a relatively rare but fatal condition. Surgical treatment of these patients is to perform early coronary revascularization concomitant with aortic repair. We review our surgical results of a selected group of 14 patients with type A acute aortic dissection and coronary artery dissection. METHODS: Between January 1993 and March 2005, 14 patients (10.2%) from a total of 136 consecutive patients with acute type A aortic dissection concomitant coronary dissection were treated by performing aortic repair and coronary artery bypass grafting. There were 11 men and 3 women (mean age, 56.7 +/- 8.4 years). The right coronary artery was involved in eight patients, the left in two patients, and both coronary arteries in four patients. At admission, nine patients had Q waves (64.2%), inferior in seven (50%) and anterior or lateral in two (14.2%). RESULTS: Hospital mortality rate was 21.4% (3 of 14 patients). Of these, two patients could not be weaned from cardiopulmonary bypass, and one patient died of multiorgan failure in the intensive care unit. CONCLUSIONS: Since acute type A aortic dissection with coronary involvement is associated with high mortality rate, immediate coronary artery bypass grafting and aortic repair is a safe and reliable approach to these challenging group of patients.
Eren et al. (Mon,) conducted a cohort in Type A acute aortic dissection and coronary artery dissection (n=14). Aortic repair and coronary artery bypass grafting was evaluated on Hospital mortality rate. Immediate coronary artery bypass grafting and aortic repair in patients with acute type A aortic dissection and coronary involvement resulted in a hospital mortality rate of 21.4%.
