    Author: Manoly I, Krishnan M, Hoschtitzky JA, Hasan R.
    Journal: Ann Thorac Surg; 2014 Sep; 98(3):e77-9. PubMed ID: 25193228.
    Abstract:
    Acute aortic valve regurgitation due to thrombosed prosthetic valve can present as a surgical emergency. This article reports a successful and unusual management of a young pregnant female patient who presented with acute aortic valve regurgitation due to a thrombosed mechanical aortic valve. As the patient had previous multiple cardiac surgeries, the options were limited for repeat aortic valve or aortic root replacement. The patient had caesarean section followed by implantation of a mechanical valve-on-valve in a previously placed composite valved conduit. This technique may be useful for reoperative valve replacement in the setting of a prior mechanical Bentall patient.
