Surgical management of coronary malperfusion due to type a aortic dissection

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Surgery

Background:

• Acute aortic dissection with coronary malperfusion is a rare but fatal condition.
• Surgical management involves early coronary revascularization alongside aortic repair.
• This study reviews outcomes in patients with type A acute aortic dissection and coronary artery dissection.

Purpose of the Study:

• To evaluate the surgical outcomes of patients with type A acute aortic dissection and concomitant coronary artery dissection.
• To assess the safety and reliability of combined aortic repair and coronary artery bypass grafting.

Main Methods:

• A retrospective review of 14 patients with acute type A aortic dissection and coronary dissection treated between 1993 and 2005.
• All patients underwent aortic repair and coronary artery bypass grafting.
• Patient demographics, coronary artery involvement, and preoperative electrocardiogram findings were analyzed.

Main Results:

• The study included 14 patients (11 male, 3 female; mean age 56.7 years).
• The right coronary artery was most commonly involved (8 patients), followed by both coronary arteries (4 patients).
• The hospital mortality rate was 21.4% (3 of 14 patients).

Conclusions:

• Acute type A aortic dissection with coronary involvement is associated with a high mortality rate.
• Immediate coronary artery bypass grafting and aortic repair is a safe and reliable approach.
• This combined surgical strategy is recommended for this challenging patient group.
