Antegrade Facilitated Antegrade Dissection and Re-Entry: A Novel Solution for Wire Across Nothing Would Follow
1Division of Cardiology, Banner University Medical Center, Phoenix, Arizona, USA.
Abstract:
A common challenge in percutaneous coronary interventions of chronic total occlusions (CTO) is balloon uncrossable lesions. It occurs when there is failure in crossing the lesion with a balloon or microcatheter after successfully crossing with a guidewire. This challenge is also not uncommon in non-CTO lesions with heavy calcification and tortuosity. Several techniques have been described to overcome this challenge during percutaneous coronary interventions of CTO and non-CTO lesions. We describe 2 cases illustrating the novel use of a Stingray catheter to perform antegrade dissection and re-entry in balloon uncrossable lesions.

Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
