Abstract
|
|
|
We report a case of leaflet embolization of central leaflet fracture a 31mm mitral Edwards-Duromedics prosthesis.
A leaflet was fractured to two segments, a larger one embolized to right common iliacartery and a smaller one to left femoral artery, respectively. Patients was reoperated with 29mm mitral Carbomedics prosthesis and incidentally found of smaller
segment
in left femoral artery at cannulation site. The embolectomy was done 15 days after cardiac operation through midline abdominal incision.
Leaflet escape of a mitral Edward-Duromedics prosthesis is a rare, postentially curable mode of valve failure. After mechanical valve replacement, unexplained heart failure and acute pulmonary edema, mechanical valve failure should be suspected.
Correct
interpretation of clinical signs, symptoms and fluroscopy should allow early diagnosis of leaflet escape and prompt surgical therapy.
