Multi-organ embolism caused by oscillating aortic valve vegetation

Abstract

Introduction: Valvular vegetation is often due to rheumatic heart disease and infective endocarditis. However, multi-arterial embolism can happen in older patients with no history of infection, fever, and cardiac symptoms. We describe a case of multi-organ embolism caused by oscillating aortal valve vegetation. Patient concerns: An 80-year-old woman without a history of infection, fever, and heart symptoms showed sudden loss of consciousness and symptoms of a multi-vessel embolism. Magnetic resonance imaging revealed multiple patchy ischemic foci in both cerebral hemispheres in the same time-phase, and echocardiography showed regurgitation in the aortic valve due to an abnormally hypo-hyperechoic mass measuring about 7.7 × 17.2 mm and oscillating aortic valve vegetation, which was induced by cardiac contraction. Diagnosis: Multiple organ cardiac embolisms caused by oscillating aortic valve vegetation. Interventions: Anti-platelet, fluid-supplement, and vascular-dilating therapies as well as intravenous diazepam were given to the patient. Outcome: The patient died of epileptic attack secondary to the cerebral embolism. Conclusions: The patient's whole-body multi-vessel ischemic events in nearly the same time-phase should have encouraged us to consider the possibility of cardiogenic embolism and thus early examination and treatment, although she was old with a relatively poor response due to early infection and physical discomfort. Clinicians should be aware that aortic valve vegetation induces generalized multi-organ embolism in the setting of infective endocarditis in order to ensure prompt recognition and treatment of this fatal complication.
