We report an unusual case of a 78-year-old male who underwent an aortic valve replacement with a 21 mm Labcor tissue porcine aortic valve due to symptomatic aortic stenosis of his native valve. Only 3 months after an uncomplicated postoperative course, on a routine follow-up, transthoracic echo showed restrictive motion of the non-coronary cusp, incomplete closure of the coaptation line and severe aortic regurgitation. The patient was scheduled for a new operation during which the previous prosthetic valve was explanted and a different model was used.
