Ventricular septal defect, echocardiogram, dog
Right long-axis echocardiographic view from a dog with a ventricular septal defect (VSD). Left: A small VSD is present in the paramembranous portion of the interventricular septum (*), allowing blood to shunt from the left ventricular outflow tract to the right ventricle just below the tricuspid valve. Right: Color flow Doppler shows turbulence associated with the left-to-right shunt. LV, left ventricle; RV, right ventricle.
