Right pulmonary artery to left atrial fistula (RPA-LAF) is a rare cardiovascular anomaly. There were no systematic and detail represent by echocardiography. We chose the patients who diagnosed with RPA-LAF at Fuwai Hospital from 2000 to 2010. All patients underwent clinical examination, chest roentgenogram, laboratory testing, electrocardiography, transthoracic echocardiography (TTE), contrast echocardiography, and cardiac catheterization. In this article, we summarize the characteristics of the TTE for diagnosing the rare cardiovascular anomaly of RPA-LAF. We undertook a detailed review of their TTE and contrast echocardiography findings to determine the characteristic findings of this condition.
