[Echocardiography of the communication between the left ventricle and the right atrium. A surgical case]

The echocardiographical appearances in left ventricular--right atrial communication are described in a patient who later underwent surgery. Cross-sectional echocardiography was most valuable. It provided an immediate diagnosis and also localised the site of the malformation which had been suggested indirectly by the appearances on M-mode scanning. The success of reparatory surgery was confirmed by the same method.
