Paradoxical septal motion in a patient with pulmonic stenosis

This case will demonstrate abnormal (paradoxical) septal motion in a 31-year-old woman with an isolated pulmonary valvular stenosis. The right ventricular volume overload was exluded by the shunt series, special angiographic studies and at surgery. The echocardiographic abnormality persisted during a restudy three months after surgery.
