Key result
CABG with a mechanical aortic connector is linked to early type A dissection.
Why the study?
The safety of using a mechanical aortic connector in patients with a history of type B dissection undergoing coronary artery bypass grafting is uncertain.
Case Report (n=1)
Mechanical aortic connectors should be used with caution during CABG in patients with a history of type B dissection due to the risk of inducing type A dissection.
Caution advised with mechanical aortic connectors after type B dissection; leaves open confirmation in larger studies.
A 75-year-old woman who had suffered type B dissection had coronary artery bypass grafting surgery using a mechanical aortic connector. Four days after the operation, she had a sudden syncope. CT demonstrated type A dissection, and an emergency operation was done, and postoperative course was uneventful. This case demonstrates that this connector should be used carefully in patients with a history of type B dissection.

Okada et al. (2004) conducted a case report in Type A dissection following CABG with mechanical aortic connector (n=1). Mechanical aortic connector was evaluated on Type A dissection. A 75-year-old woman with a history of type B dissection developed type A dissection four days after CABG using a mechanical aortic connector, requiring emergency surgery.
