A, B. Transthoracic echocardiography (short axis) shows an aneurysm (arrow) and intraventricular turbulences; C, D. Cardiac computed tomography shows an aneurysm of a patch closing interventricular septal defect which is bulging into the right ventricle and causing significant stenosis of the right ventricle outflow; E, F. Transthoracic echocardiography (short axis) shows postsurgical right ventricular outflow tract (RVOT); LA : left atrium; LV : left ventricle RA : right atrium; RVIT : right ventricular inflow tract.

Also, insignificant left-to-right shunt (Fig. 1A, B) was detected. The cardiac computed tomography confirmed a large protrusion of the patch closing VSD causing obstruction within the RV (Fig. 1C, D). TTE showed (Fig. 1E, F) normal dimensions and contractility of the RV; the pressure gradient within of the RV outflow was 12 mmHg. The patient was discharged in good condition.
