Multimodality imaging evaluation of multilobulated subvalvular aortic aneurysm involving the membranous ventricular septum.

We report a rare clinical case of multilobulated subvalvular aortic aneurysm located in the left ventricular outflow tract, involving the membranous ventricular septum, and associated with mild prolapse of the noncoronary aortic leaflet, emphasizing the importance of multimodality imaging approach, and multidisciplinary discussion.

Thrombolysis in acute nonmassive pulmonary embolism: potential role of multidetector-row spiral computed tomography in decision making.

In the setting of suspected or confirmed nonmassive pulmonary embolism (PE), transthoracic echocardiography (TTE) is an important tool to identify patients who could benefit from thrombolytic therapy, because of right ventricle (RV) dysfunction, and to monitor the dynamic response of the RV to reperfusion therapy. Unfortunately, certain patient characteristics such as obesity, lung disease, postsurgical state, or respiratory distress often lead to inadequate ultrasonographic imaging quality. In such patients, multidetector-row spiral computed tomography (MSCT) may become even more important. We present a female obese patient with acute nonmassive PE in whom TTE did not allow a reliable evaluation of the RV. Conversely, MSCT, beyond a direct demonstration of intravascular thrombi, detected multiple signs suggesting RV dysfunction. According to these findings, thrombolysis was safely performed, obtaining a rapid clinical improvement and a regression of RV dysfunction.
