A 40-year-old woman admitted with heart failure had undergone aortic valve replacement with a Model 2310 Starr-Edwards valve due to aortic regurgitation 33 years previously. She had been followed up for several years, but discontinued follow-up and medication (including Warfarin) for the past 25 years. Echocardiography demonstrated marked dilatation and thickening of the left ventricle, and the peak pressure gradient of the prosthesis was measured as 87.9 mmHg. Under the diagnosis of chronic aortic valve prosthesis-patient mismatch with subsequent severe left ventricular dysfunction, the Starr-Edwards valve was explanted and replaced with a 23 mm St Jude Medical prosthetic valve. The removed valve showed minimal cloth wear except for a small part of the strut The postoperative echocardiography demonstrated recovering of left ventricular function. To our best knowledge, this case presents the longest duration for a surgically explanted Starr-Edwards aortic prosthetic valve in Japan.
