Abstract

Sinus of Valsalva aneurysms are rare cardiac anomalies. They can be congenital or acquired, and mainly involve the right or non-coronary sinuses. Unruptured aneurysms are usually asymptomatic unless they compress other structures or produce thrombi. A sinus of Valsalva aneurysm can also produce myocardial infarction through thrombus formation secondary to the turbulent flow in the Valsalva aneurysm. We report a case of a huge sinus of Valsalva aneurysm involving the noncoronary sinus, which was diagnosed as the presumed source of acute myocardial infarction.

  Fig. 1 TTE images of the SVA. A huge SVA (7.6×5.8 cm in diameter) is compressing the LA in the parasternal long axis (A) and apical 4 chamber views (B). SVA: sinus of Valsalva aneurysm, LA: left atrium, LV: left ventricle, RV: right ventricle.

• 

  Fig. 2 TEE image of a SVA. The SVA originating from the non-coronary sinus extends to the interatrial septum and severe spontaneous echo contrast is observed in the short axis view. SVA: sinus of Valsalva aneurysm, RA: right atrium.

• 

  Fig. 3 A huge SVA arising from the non-coronary cusp is seen in the chest cardiac tomography image.
