Figure 2: (a) Left ventricle inflow–outflow Doppler showing presystolic forward flow into the aorta (yellow arrow). This finding suggests increased stiffness of the left ventricle due to endocardial inflammation resulting in a significant increase in left ventricular pressure during left atrial contraction leading to presystolic forward flow into the aorta. (b) Left ventricle inflow–outflow Doppler showing forward flow into the aorta (yellow arrow) during the isovolumetric contraction time
