Combined Interatrial and Intrapulmonary Shunting in Orthodeoxia Detected by Transesophageal Echocardiography

Abstract

Contrast transesophageal echocardiography was found useful in diagnosing combined interatrial and intrapulmonary right‐to‐left shunts in a patient presenting with orthodeoxia. This was done by separately examining the pulmonary veins and the interatrial septum during intravenous normal saline injections.
