The volume of dye in the balloon has been correlated with its maximal diameter. Thus, a no. 810 French heter filled with 10 ml of diatrizoate (50 percent) has a diameter of approximately 25 mm and a no. 822 French heter filled with 40 ml of diatrizoate a diameter of approximately 43 mm. Persistent arrhythmias or other adverse effects of the procedure were not observed.
