A 49‐year‐old man who had undergone tricuspid valve replacement with a Bjöork‐Shiley prosthesis in November 1974 was reoperated on in January 1985 due to prosthesis malfunction. The operation revealed a totally occluded prosthetic valve and a paravalvular defect which had served as the channel for atrioventricular blood flow. In retrospect, all evidence indicated that the valve had stuck as early as six months after the primary operation, when the patient had first noticed the loss of audible valve clicks and the reappearance of effort intolerance. Due to the gradual progression of the patient's symptoms and misinterpretation of the significance of absent valve clicks, the correct diagnosis was not made until a follow‐up study 10 years after the first operation when contrast echocardiography showed the absence of both disc movements and transvalvular contrast flow. Our experience indicates that thrombosis of a tricuspid valve prosthesis may present highly insidiously and that the loss of audible valve clicks should be relied on as a sign of prosthesis malfunction.
