Contrast echocardiography in the evaluation of interatrial septal defect.
One hundred twenty-four adult patients consecutively referred for suspected interatrial septal defect (IASD) were studied with contrast echocardiography. In 58 the study eliminated altogether the diagnosis of any significant cardiac defect. Fifteen patients had other forms of cardiac abnormalities with no shunting of blood, and 51 patients had echocontrast study positive for interatrial shunting; 48 of these were subsequently proven by cardiac catheterization to have IASD. Echocontrast provided a highly sensitive and specific means of both diagnosing IASD and eliminating this diagnosis.
