Fig. 6From: Utility of magnetic resonance imaging in the evaluation of left ventricular thickening3-chamber cine SSFP image shows concentric LV thickening. There is flow acceleration in the LVOT below the level of the aortic valve (straight arrow). There is a linear discrete membrane at the LVOT (curved arrow), which is responsible for the flow acceleration, consistent with a subaortic membraneBack to article page
