CDFI: the main pulmonary artery exploration and descending aorta from left to right continuous shunt flow spectrum, the peak flow rate of 3.3m / s, the peak pressure difference of 43.3 mm Hg. Diastolic septal foramen ovale can detect and 2.0mm, left to right shunt signal (Figure 1), suggesting: congenital heart
