A complex Stanford type A aortic dissection in a patient with prior heart surgery was successfully treated. The repair involved ascending aorta replacement and addressing a fistula and coronary artery involvement.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Disease
Background:
- The patient had a history of aortic valve replacement, atrial fibrillation, and non-ischemic cardiomyopathy.
- Stanford type A aortic dissection presents a significant surgical challenge, especially in patients with prior cardiac procedures.
Purpose of the Study:
- To report a complex case of Stanford type A aortic dissection.
- To describe the surgical management of aortic dissection involving the right ventricular outflow tract and coronary ostium.
Main Methods:
- Emergent ascending aorta replacement was performed.
- Intraoperative findings included a large dissected aneurysm with extension into the right ventricular outflow tract.
- Surgical repair involved ascending aortic replacement, patch repair of an aorto-cameral fistula, and primary repair of the right coronary ostium.
Main Results:
- The patient underwent successful surgical repair.
- The aorto-cameral fistula and right coronary ostium were successfully reconstructed.
Conclusions:
- Complex Stanford type A aortic dissections can be successfully managed with emergent surgical intervention.
- Meticulous surgical technique is crucial for repairing dissections involving vital structures like the right ventricular outflow tract and coronary arteries.
