Spontaneous aortic valve thrombosis, a rare condition, occurred in a patient without typical risk factors. Surgical intervention successfully removed the organized thrombus, and the patient recovered well.

Area of Science:

  • Cardiology
  • Cardiovascular Surgery
  • Pathology

Background:

  • Spontaneous aortic valve thrombosis is rare, often linked to trauma or infection.
  • Native aortic valve thrombosis without predisposing factors is exceptionally uncommon.

Observation:

  • A 65-year-old woman with prior retinal artery occlusion and severe aortic stenosis presented with a mobile mass on the aortic valve.
  • Transesophageal echocardiography identified the mass; no hypercoagulable state or infection was detected.

Findings:

  • Surgical resection revealed a partially organized, adherent thrombotic mass on the ventricular surface of the severely stenotic aortic valve.
  • Histological examination confirmed an organized thrombus, distinct from infective endocarditis or primary hypercoagulable states.

Implications:

  • This case highlights the possibility of aortic valve thrombosis in the absence of common risk factors.
  • Successful surgical management of aortic valve thrombosis can lead to favorable patient outcomes.
