Mentions: Cannulation of the patient's coronary sinus using a long sheath multipolar catheter was difficult and the catheter was positioned in the interatrial septum. The tip of the catheter was directed to the left atrium (Fig. 1A). Angiography using the long sheath catheter showed a vein (Fig. 1B, arrows) draining to the left atrial appendage (Fig. 1B, arrowheads). The septal vein of the left atrium could be visualized in the right anterior oblique (Fig. 1C) and left anterior oblique views (Fig. 1D) after placement of a multipolar catheter in the coronary sinus. Atrioventricular nodal reentrant tachycardia was induced by programmed electrical stimulation and slow pathway modification was performed successfully.
