“…Review of the publi shed cases of poppet escape from artificial mitral valves reveals th at survival is often po ssible when surgical intervention is promptly carried out (Table I) atrium (6,18) , but more often in the aor ta: impacted in the distal aortic arch (9), in the descending aorta (10) , just above the iliac axis ( 15), in th e proximit y of the renal art eries ( 12), in the lower abdominal aorta ( 1, 19) , or at the aort ic bifurcation (12). With these considerations in mind and in absence of evidence of arterial obstruction, we, as oth ers (19), decided not to do an exploratory operation.…”

A case of the escape of the disc occluder from a Beall model 104 mitral valve implanted 12 years earlier is reported. Acute dysfunction of the prosthesis was diagnosed and prompt operation was carried out. The patient, who was admitted in cardiogenic shock and pulmonary edema, survived and had a smooth postoperative course. Unnecessary investigations, which result in a delay of surgery, should be avoided under these circumstances. Since escape of the disc is rare with this type of valve (only one case has previously reported) elective reoperation is not recommended, but attention should be paid to the appearance of premonitory symptoms which may precede this dramatic event. Various investigations failed to located the embolized disc. Since no evidence of arterial obstruction was present, the patient was not submitted to an exploratory operation.

Embolization of discs from various prosthetic mitral valves produces fulminant cardiac failure with possible survival after emergent mitral valve prosthetic replacement. The embolized discs lodge in the aorta at various levels parallel to the blood stream and have not occluded distal flow. Some embolized discs have been left in the aorta for as long as 12 years. An embolized disc left in the abdominal aorta produced renal artery occlusion 5 years after embolization in the reported case. A previous case produced mesenteric ischemia after 1 month. Localization of embolized discs has at times been difficult with success and failure by plain x-ray films, ultrasound, angiography, and CT scans in some cases. Since embolized discs have not produced acute problems with ischemia, delay of retrieval after emergent mitral valve replacement does not seen detrimental. Late complications may occur as with the present case and removal of asymptomatic embolized discs seems advisable and prudent.
