'Caput medusae': tension reduction on a dehiscent native annulus in valve implantation in an endocarditis case
1Department of Cardiovascular Surgery, Heart Center Brandenburg, Brandenburg Medical School, Bernau, Germany.
Abstract:
Interrupted pledget-armed braided sutures are widely used for valve implantation. In a 74-year-old woman with aortic valve endocarditis and shallow annular abscess, annulus dehiscence resulted after resection. As resistance was too high for sufficient primary approximation, a snug fit of the valve by means of circumferential application of curbed tourniquets resembling Medusa's head after suture placement was achieved. Closest possible approximation of the upper and lower part of the annulus with the prosthesis prior to final fixation was thus possible, so that application of too much tension on a single suture could be avoided.
