We present the case of a 2.5 years old male, a known case of WS who presented with cognitive delay, a history of right-sided stroke and left hemiplegia. Echocardiography revealed severe SVAS with a gradient of 105 mmHg. The diameter of the Sino tubular junction was 4 mm. Computerized tomography angiogram showed diffuse stenosis of ascending aorta with intraluminal thrombus. At surgery, the ascending aorta was augmented with autologous pericardial patches and end-to-end anastomosis of the proximal and distal aorta completed the reconstruction. The patient was discharged in a stable condition. He presented 6 weeks post-op with a pulsating pseudoaneurysm through the sternal wound. Emergency surgery with the removal of fungal vegetation and reconstruction of the ascending aorta was performed. He expired due to fungal sepsis a week later.
