Abstract:
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.
