RESUMO
We present the exceedingly rare case of an 18-year-old boy with recurrent syncope attacks and dyspnea at rest for 3 weeks. Transthoracic echocardiography showed a giant aneurysm dilatation occupying the left ventricular outflow tract. The intraoperative finding was a giant thick-walled unruptured aneurysm of the sinus of Valsalva from the right coronary cusp. The roof of the aneurysm was excised and the defect was repaired, sparing the aortic valve. Histopathology analysis from the roof of the wall of the aneurysm revealed features of endarteritis obliterans of the vasa vasora in keeping with syphilitic infection with aneurysmal dilation. A rapid plasma reagin test was reactive.

We present an exceedingly rare case of right ventricular outflow tract obstructing mass in an adult patient who presented with dyspnea and dizziness. Transthoracic echocardiography and computed tomography angiogram of the chest showed a large mass in the right ventricle obstructing the outflow tract. A dual right ventriculotomy and right atriotomy surgical approach was taken to completely resect the mass from the interventricular septum, which subsequently confirmed histopathologically the mass as a mature cystic teratoma.
