A simple plain Radiographic method for anticipating the adequacy of left ventricular size in Tetralogy of Fallot (T.O.F.) by studying the level of cardiac dome (i.e.) the dome in contact with cardiaic apex is described. Out of eighty one patients with good sized left ventricle, seventy had low placed cardiac dome and eleven had equal domes. In nineteen patients with small left ventricle, the cardiac dome was high placed. In Tetralogy of Fallot, equal domes and low placed cardiac dome suggest good sized left ventricle. A high placed cardiac dome indicates small sized left ventricle. This information is useful to anticipate adequacy of left ventricular size to cope up with systemic circulation post-operatively. While the plain Radiographic indication of adequate sized left ventricle in Tetralogy migh obviate the need for left ventriculogram, a small sized left ventricle anticipated on plain radiograph will, in fact, indicate left ventricular angiographic corroboration and evaluation.
