Multi-slice CT demonstration of sinus of Valsalva rupture

Aneurysms of the sinus of Valsalva are rare. We report here the case of a 56-year-old man with a ruptured aneurysm of sinus of Valsalva with flow into the right ventricle which was diagnosed non-invasively by 64-row multi-slice computed tomographic (CT) imaging. The right sinus of Valsalva aneurysm rupturing into the right ventricular outflow region might be silent or symptomless in many cases. The patient also had mild symptom. For anatomical demonstration, contrast-enhanced CT was performed. Although the ruptured sinus of Valsalva was initially diagnosed by echocardiography, CT images did give our surgeons a better three-dimensional appreciation when surgical repair was performed. Multi-slice CT imaging should be considered the technique of choice for both diagnosis and follow-up examination of the aneurysm of sinus of Valsalva and its rupture.
