title: Retrograde Percutaneous Coronary Intervention for Left Anterior Descending Chronic Total Occlusion Via an Ipsilateral Intraseptal Collateral Channel Using a Single Guiding Catheter.
abstract: Successful recanalization of chronic total occlusion (CTO) of coronary arteries has improved symptoms and mortality. In CTO cases, retrograde approach from opposite coronary artery has a better chance of procedural success. But the retrograde approach from opposite site is not always suitable. In certain CTO cases, the distal left anterior descending (LAD) artery is supplied from the intraseptal collateral channel. Controlled antegrade and retrograde tracking (CART) strategy has been developed to improve guidewire crossing and successful recanalization. We report a case of the retrograde percutaneous coronary intervention for the LAD CTO lesion via an ipsilateral intraseptal collateral channel, which was successfully revascularized with reverse CARTtechnique using a single 8-French guiding catheter.
