A 79-year-old man underwent bioprosthetic valve replacement for aortic regurgitation 10 years previously (Carpentier-Edwards PERIMOUNT Magna Ease, 21 mm; Edwards Lifesciences, Irvine, CA, USA). The indexed effective orifice area decreased to 0.422 cm2/m2, and heart failure symptoms appeared. The patient underwent aortic valve replacement through a redo median sternotomy. A perivalvular leak was observed on transesophageal echocardiography at the time of weaning from cardiopulmonary bypass. The patient was judged to have a leak characteristic of bioprosthetic valves and was monitored closely. Postoperative echocardiography showed that the perivalvular leak had decreased to a trivial level, indicating that the intraoperative decision had been correct. We report this case because such intraoperative judgments are difficult to make.
