[Acute aortic dissection with anomalous coronary artery].

Area of Science:

• Cardiovascular Surgery
• Anatomical Variations
• Aortic Diseases

Background:

• Acute type A aortic dissection is a life-threatening condition requiring immediate surgical intervention.
• Severe aortic regurgitation often accompanies aortic dissection, necessitating valve and aortic root repair.
• Anomalous coronary artery origins are rare but can be associated with myocardial ischemia.

Observation:

• A 38-year-old male presented with acute type A aortic dissection and severe aortic regurgitation.
• During emergency repair using the Bentall procedure, an anomalous right coronary artery was identified.
• The anomalous coronary artery was successfully managed with a single coronary button technique.

Findings:

• The study highlights the intraoperative discovery of an anomalous right coronary artery in a patient undergoing aortic dissection repair.
• Successful surgical management of the anomalous coronary artery using the single coronary button technique was achieved.
• This case expands the known associations of anomalous coronary arteries beyond ischemic heart disease.

Implications:

• Intraoperative identification and management of coronary artery anomalies are crucial during complex aortic surgeries.
• The single coronary button technique offers a viable solution for repairing anomalous coronary arteries in this context.
• Awareness of potential coronary anomalies during aortic dissection surgery can prevent future cardiac complications.
