Aortic Saddle Embolism Caused by Mitral Valve Vegetation

Abstract

Aortic saddle embolus accounts for approximately 10% of all peripheral arterial emboli. The most common sources of emboli are left atrial thrombi associated with atrial fibrillation and vegetation. A 22-year-old male patient was admitted due to acute onset of orthopnea, tachypea and cough. Transthoracic and transesophageal echocardiography showed huge vegetation 3 2cm of the posterior mitral valve leaflet which was associated with severe mitral regurgitation. On 14th hospital day, he suffered from sudden onset of weakness, pain, and coldness on both lower extremities. Follow up echocardiography showed marked size reduction of the original mitral valve vegetation. Angiography showed aortic saddle embolus. The embolectomy of aortic saddle embolus was performed through the transfemoral approach with a Forgarty catheter. At the same time, removal of the infected mitral valve and mitral valve replacement were performed. KEY WORDS Aortic saddle embolism·Mitral valve vegetation·Echocardiography.증 례
