Video 1. CC0 septal collateral selected for retrograde crossing. Representative deidentified angiographic video showing the baseline appearance of a CC0 septal collateral selected for retrograde crossing. The video is provided for illustrative purposes only and was not used for quantitative analysis. CC = collateral connection.

Video 2. Successful retrograde crossing of a CC0 septal collateral using the surfing technique. Representative deidentified angiographic video showing successful retrograde crossing of the same CC0 septal collateral shown in Video 1 using the surfing technique, resulting in establishment of the retrograde route. The video is provided for illustrative purposes only and was not used for quantitative analysis. CC = collateral connection.

Video 3. Final angiographic result after successful retrograde CTO PCI. Representative deidentified angiographic video showing the final angiographic result after successful retrograde CTO PCI in the same patient shown in Videos 1 and 2. The video is provided for illustrative purposes only and was not used for quantitative analysis. CTO = chronic total occlusion; PCI = percutaneous coronary intervention.
