Abstract
We present a case of aortic dissection associated with systemic infection. Transesophageal echocardiography demonstrated calcified stenotic aortic valves and dissection of proximal ascending aorta that filled with an echoic mass, which was found as an abscess caused by methicillin-resistant staphylococcus aureus. We suspected that the jet flow of aortic stenosis combined with systemic inflammatory disease contributed to intimal tear and dissection of the aortic wall that led to the development of abscess inside the false lumen in the particular patient.
