Figure 2 A: Coronary venography in the right anterior oblique view shows angulated and tortuous coronary sinus branches. B: Enlarged view of the square in A. The black arrow indicates the tip of the inner guide catheter. The white arrow indicates severe stenosis with small collateral branches (arrowheads) of the lateral vein. C: The lesion was dilated with a balloon. Balloon indentation (arrowhead) implies insufficient dilation of the lateral vein. D: Application of the anchor balloon technique. The balloon was inflated in a distal lesion of the lateral vein (arrowhead) and its shaft was held with backward force while the inner guide catheter was being advanced. The inner guide catheter was able to cross the tortuous lateral vein (arrow). E: A left ventricular lead was positioned at the midportion of the lateral branch. F: Chest radiograph after device implantation. LV = left ventricular lead; RA = right atrial lead; RV = right ventricular lead.
