title: A case of unruptured aneurysm of the right sinus of valsalva with right ventricular outflow obstruction.
abstract: A 66-year-old man presented with exertional dyspnea. He was found to have an unruptured aneurysm of the right sinus of Valsalva causing significant right ventricular outflow obstruction. This aneurysm was diagnosed by transthoracic two-dimensional echocardiography, transthoracic three-dimensional echocardiography, transesophageal echocardiography, contrast echocardiography and 64-slice multidetector cardiac computed tomography. Because unruptured aneurysms of the sinus of Valsalva are rarely symptomatic, they can be difficult to detect. However, the unruptured aneurysm of the right sinus of Valsalva in this case caused significant right ventricular outflow tract obstruction, resulting in exertional dyspnea.
