Left ventricular outflow tract obstruction by thickened anterior mitral valve leaflet in a patient with tetralogy of Fallot

A 17-month-old male child presented with cyanosis and failure to thrive. Transthoracic echocardiography suggested a diagnosis of tetralogy of Fallot (TOF). The mitral valve leaflets were thickened without any hemodynamic evidence of stenosis or regurgitation and a normal-sized left atrium (LA). Concentric left ventricular hypertrophy (LVH) was also noted. Patient was referred for a computed tomography angiography (CTA) for better characterization of the cardiac and extracardiac anomalies. The scan was performed on a SOMATOM FORCE (Siemens Healthcare, Forchheim, Germany) CT scanner which is a third-generation dual source CT scanner (2  × 192 slices) with a temporal resolution of 66 ms, rotation time of 0.25 s and spatial resolution of 0.24 mm.
