Key result
Operative valve replacement successfully treats late Omnicarbon valve leaflet fracture and aortic embolization.
Why the study?
Mechanical disruption including leaflet fracture has been described in many artificial valves but not previously reported in the Omnicarbon monoleaflet valve.
Case Report (n=1)
This is the first reported case of leaflet fracture with aortic embolization in an Omnicarbon monoleaflet valve, which was successfully diagnosed with imaging and treated with surgery.

Rare Omnicarbon valve failure warrants clinical vigilance; leaves open durability questions for monoleaflet prostheses.
In almost every type of artificial valve, mechanical disruption has been described. We present the first case of leaflet fracture with aortic embolization in an Omnicarbon monoleaflet valve 42 months after implantation. The 22-year-old male patient suffered of acute respiratory insufficiency and was referred to our hospital as an emergency case. Until a few days before presentation, he was in good condition without clinical complaints. By means of transesophageal echocardiography (TEE) and abdominal sonography the diagnosis of leaflet fracture with embolization to the abdominal aorta could be made. The patient underwent consecutive operative valve replacement and foreign body extraction that resulted in a complete recovery.

Kornberg et al. (1999) conducted a case report in Leaflet fracture with aortic embolization (n=1). Omnicarbon monoleaflet valve was evaluated on Leaflet fracture with aortic embolization. A 22-year-old male experienced leaflet fracture and aortic embolization 42 months after Omnicarbon monoleaflet valve implantation, which was successfully treated with operative valve replacement.
