Radiologic search for embolized leaflets of prosthetic heart valves: A report of two cases

Abstract: In a radiologic search for embolized leaflets of Edwards-Duromedics bileaflet valves in 2 patients, the embolized fragments were localized in the iliac vessels using computed tomography. Sonography was successful in one case and standard X-ray films of the abdomen were negative in both cases. In vitro investigations with Björk-Shiley and Edwards-Duromedics leaflets suggested that standard X-ray films of the abdomen and pelvis should be considered as the first investigational technique. If negative, computed to… Show more

Tsui et al [7], Dimitri and Williams [10], and Schurawitzki et al [11] also reported that missing leaflets were readily visualized with CT. We did not perform fluoroscopy or angiography examinations because of the insufficient radioopacity of the escaped leaflet on plain radiography.…”
