Diagnostic Considerations
Clinicians should keep in mind sinus of Valsalva aneurysm (SVA) rupture in young patients (especially those with minimal cardiac risk factors) who have signs and symptoms of myocardial ischemia, heart failure, or cardiac conduction defects. Definitive treatment is available, yet the prognosis is poor if rapid diagnosis cannot be made.
Other conditions to consider include chest pain and arrhythmia/syncope. In addition, SVA may mimic myocardial infarction or present with cerebrovascular embolism. [15, 16]

Sinus of Valsalva Aneurysm. An axial slice from an electrocardiography (ECG)-gated computed tomographic angiogram (CTA) demonstrates an aneurysm of the right sinus of Valsalva (arrow). There is a filling defect within the aneurysm consistent with a thrombus.

Sinus of Valsalva Aneurysm. A parasagittal slice from an electrocardiography (ECG)-gated computed tomographic angiogram (CTA) demonstrates a right sinus of Valsalva aneurysm (arrow). There is a filling defect within the aneurysm consistent with a thrombus.

Sinus of Valsalva Aneurysm. A three-dimensional reconstruction of a computed tomographic (CT) aortogram is shown, demonstrating a right sinus of Valsalva aneurysm (arrow).

Sinus of Valsalva Aneurysm. A mid-esophageal short-axis echocardiogram demonstrates a ruptured right sinus of Valsalva aneurysm. Color doppler demonstrates flow into the right ventricle.
