Paired long axis images with and without color flow mapping demonstrating tricuspid valve tissue apposed to the ventricular septal defect (VSD, arrows) which is partially occluding the defect. In the right hand panel, color flow mapping demonstrates residual flow around this tricuspid valve tissue.
LV: left ventricle; LA: left atrium; RV: right ventricle; AO: aorta; MV: mitral valve; arrows: VSD.
