An Unusual Complication of Infective Endocarditis Treated by Percutaneous Intervention

Mycotic pseudoaneurysms (PA) are an infrequent complication of infective endocarditis (IE). However, due to advanced imaging modality and early therapy, this complication has been seen less frequently in the past few years. The reported incidence is 5%–15% of the patients, with the most common site being intracranial vessels (up to 65%), followed by abdominal and then peripheral vessels. We describe a young patient with a bicuspid aortic valve complicated by IE, who developed a giant mycotic PA. This was treated with a cover stent of the aneurysmal segment, which was complicated by distal stent migration and eventually managed with bypass surgery.
