Abstract

There have been few case reports on giant sinus of Valsalva aneurysm (SVA). We report a case of a giant unruptured right coronary SVA that was confused with a pericardial cyst by transthoracic echocardiography.

Figure

• 

  Fig. 1 Chest radiography showed prominent right heart border (arrow) with mild cardiomegaly.

• 

  Fig. 2 Transthoracic echocardiography obtained in a parasternal long axis (A) showed aneurysmal structure (arrows) arising from unknown origin. Apical 4-chamber view (B) revealed a balloon-like mass (arrows), occupying almost completely the right atrium. Parasternal short axis view (C) showed that origin (arrow) of aneurysm was visualized from right coronary sinus with blood flow from aortic root to aneurysm.

• 

  Fig. 3 Thoracic CT showed a large saccular lesion, arising from the right coronary sinus of Valsalva (arrow).

• 

  Fig. 4 Coronary angiography revealed a large unruptured aneurysm in the sinus of Valsalva arising from the right coronary sinus.
