We have reported a case of trans-cuff leakage that occurred in a composite graft of bio-Bentall operation. The leakage resolved several months after surgery, similar to the trans-cuff leakage seen in simple aortic valve replacement. We have proposed hypotheses on the mechanism of trans-cuff leakage during a bio-Bentall operation and suggested ways to prevent it from occurring.
Keywords: Bentall operation; bioprosthesis; trans-cuff leakage.
