Bottom Line: 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.However, the unruptured aneurysm of the right sinus of Valsalva in this case caused significant right ventricular outflow tract obstruction, resulting in exertional dyspnea.

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.

The substernal view after administration of intravenous echo contrast demonstrates the significant border between the body of the aneurysm and the right ventricle. An: body of the aneurysm, AoV: aortic valve, PA: main pulmonary artery, RA: right atrium, RV: right ventricle, RVOT: right ventricular outflow tract.

Figure 3: The substernal view after administration of intravenous echo contrast demonstrates the significant border between the body of the aneurysm and the right ventricle. An: body of the aneurysm, AoV: aortic valve, PA: main pulmonary artery, RA: right atrium, RV: right ventricle, RVOT: right ventricular outflow tract.

Mentions: As mentioned above, transesophageal echocardiography revealed aneurysm; however, further cardiac abnormalities were not identified. On contrast echocardiography, subcostal images demonstrated a significant border between the body of the aneurysm and the chamber of the right ventricle upon administration of intravenous echo contrast (Fig. 3). 64-slice multidetector computed tomography (MDCT) showed the presence of an eccentric, lobulated, 3.5 cm aneurysm protruding into the RVOT, with the upper lobulated part located just below the pulmonary valve and the digital-shaped lower part obstructing the RVOT (Fig. 4).
