Alerts to rare leaflet embolization in acute prosthetic regurgitation; leaves open incidence and surveillance needs for On-X valves.
BACKGROUND: Structural valve failure in the form of leaflet fracture and embolization is an uncommon complication. Severe valve regurgitation with pulmonary oedema in a patient with a history of a prosthetic cardiac valve requires urgent diagnosis. An echocardiogram is essential in identifying the cause of valve failure. CASE PRESENTATION: We report a case of a 21-year-old male patient who presented with acute pulmonary oedema due to fracture and embolization of a leaflet of an On-X mitral valve four years post-implant. He underwent an emergency redo mitral valve replacement with a good outcome. CONCLUSIONS: Structural valve failure with leaflet fracture and embolization is an extremely rare complication and may be fatal. Good clinical acumen is required for prompt diagnosis in any patient who presents with a circulatory collapse in the presence of a history of previous cardiac surgery. Once the diagnosis is made, the patient should undergo emergency redo valve replacement surgery.

Sidali et al. (2022) conducted a case report in On-X mitral valve leaflet embolization presenting as acute pulmonary oedema (n=1). Emergency redo mitral valve replacement and surgical extraction was evaluated on Patient outcome. Emergency redo mitral valve replacement and surgical extraction successfully treated a 21-year-old male presenting with acute pulmonary oedema due to an extremely rare On-X mitral valve leaflet fracture and embolization.
