title: Double guiding catheters for complex percutaneous coronary intervention.
abstract: A large-lumen guiding catheter is often used for complex percutaneous coronary intervention-particularly when a final kissing-balloon or 2-stent technique is required. However, catheter insertion is sometimes restricted by diseased vascular access sites or a tortuous vascular route.We report 2 cases in which a unique double guiding catheter technique was used to create a lumen of sufficient size for complex percutaneous coronary intervention. In each patient, two 6F guiding catheters were used concurrently to engage the ostium of 1 target vessel. In 1 patient, these catheters were used for the delivery of 2 balloons to complete kissing-balloon dilation after single-stent placement. In the other patient, the catheters were used to deliver 2 stents sequentially to their respective target lesions. The stents were then deployed simultaneously as kissing stents, followed by high-pressure kissing-balloon postdilation.
