Virtual angioscopy with multidetector computed tomography for the diagnosis of pannus formation in mechanical aortic valves Free

Pannus did not interrupt the valve (A). The pannus was revealed after taking the aortic valve with the narrowing of the outflow tract (B). Virtual angioscopy with multidetector computed tomography detected the pannus at the subvalvular position (C), which was difficult to detect by fluoroscopy, transoesophageal echocardiography (D) and 3D computed tomography (E). LCA: left coronary artery; RCA: right coronary artery.
