OPEN-AP CTO PCI Residual Angina Prediction Tool

The OPEN-CTO registry is an observational cohort of 1,000 consecutive patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) at 12 high-volume centers in the U.S. The OPEN-AP tool uses data from the OPEN-CTO registry to estimate the expected magnitude of angina reduction from attempted CTO PCI, as well as the amount of residual angina patients might expect at 6 months after the procedure. These estimates are averages and are NOT guaranteed outcomes for specific individuals, but they may be useful in discussions between patients and their doctors on the risks and benefits of a CTO PCI procedure.
