An insidious Aggregatibacter actinomycetemcomitans infection of an ascending aortic endovascular graft

Abstract

While HACEK group organisms cause only 1–3% of infective endocarditis (IE) cases, their insidious and varied clinical presentations make for difficult and often delayed diagnoses. We present a 65-year-old male with persistent exertional dyspnea, hemoptysis, and weight loss who was diagnosed with a HACEK aortic graft infection and IE.
