Figure 3 Sequence of fluoroscopy imaging of trans-septal puncture in the same projection (left anterior oblique view). A: The esotherm sound for the esophageal temperature control and coronary sinus catheter are in place. The “SafeSept” guidewire penetrates the fossa ovalis; B: The “SafeSept” guidewire is visible in the left atrium thanks to radiopaque coil; C: The trans-septal assembly (needle, dilator and sheath) is placed in the right atrium before crossing the fossa ovalis; D: The distal part of trans-septal guidewire is positioned in the left superior pulmonary vein.
