Systemic Embolization of the Disk Occluder of the Wada-Cutter Prosthetic Valve

A Late Complication

The results in 22 patients in the Denver area with Wada-Cutter prostheses were reviewed. There were 14 late deaths, with an average follow-up of six years. Four cases of valve malfunction not related to thrombosis were documented. There were three cases of embolization of the occluder. A survivor is reported. Clinical evaluation of the group suggested new mitral regurgitation to be a sensitive indicator of impending embolization of the occluder. Documentation of valve malfunction warrants valvular replacement.
