Retrograde Dissection Reentry for Coronary Chronic Total Occlusions.

The retrograde technique is an important aspect to overall success in percutaneous coronary intervention of chronic total occlusions. The reverse controlled antegrade and retrograde subintimal tracking technique is the most commonly used retrograde approach for recanalization as either a primary approach or after unsuccessful antegrade dissection reentry. A stepwise approach to this technique is the key to success.
