title: Injection of contrast medium within the interatrial septum: an unusual complication of right atrial angiography.
abstract: A 56-year-old male with right ventricular dysplasia underwent right atrial angiography. Though the catheter tip appeared to be in the right atrial cavity, an appreciable amount of contrast medium dissected the interatrial septum, resulting in unusual radiologic and ultrasonic patterns.
