Abstract
An asymptomatic 78-year-old man with no major medical history was diagnosed with an unruptured sinus of Valsalva aneurysm. The complexity of the anatomic relationships around the aneurysm when observed only by preoperative contrast-enhanced computed tomography and transthoracic echocardiography made it difficult to choose a treatment strategy. Accordingly, virtual imaging was reconstructed from the computed tomography data. Autologous pericardial patch closure with sparing of the aortic valve and annulus was successfully performed on the basis of virtual imaging.
