Coronary artery disease in aortic surgery.

Area of Science:

• Cardiology
• Cardiac Surgery

Background:

• Coronary artery disease (CAD) is prevalent in patients requiring aortic surgery.
• The optimal management of concurrent CAD and aortic disease remains a critical clinical question.

Purpose of the Study:

• To prospectively analyze the incidence of CAD in patients undergoing aortic surgery.
• To evaluate the impact of aggressive preoperative cardiac catheterization and myocardial revascularization on outcomes.

Main Methods:

• Prospective analysis of 59 patients undergoing aortic surgery.
• Assessment of coronary artery disease prevalence through cardiac catheterization.
• Evaluation of myocardial revascularization (coronary artery bypass grafting) prior to aortic surgery.
• Analysis of operative mortality and overall mortality associated with the approach.

Main Results:

• 75% of patients had at least one-vessel CAD; 32% had three-vessel or left main disease.
• Preoperative cardiac catheterization and revascularization were performed in 29% of patients.
• Operative mortality was 3.7%, with an overall mortality of 7.4% for the aggressive approach.
• Resting and exercise multiple-gated acquisition scans did not reliably predict CAD in asymptomatic patients.

Conclusions:

• Aggressive preoperative cardiac catheterization and coronary artery bypass grafting reduce the risk of cardiac complications in patients undergoing aortic surgery.
• This strategy appears to improve outcomes despite potential risks associated with staged procedures.
