Background-Percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) is superior tofibrinolysis when performed in a timely manner in high-volume centers. Recent European trials suggest that transfer for PCI also may be superior to fibrinolysis and increase access to PCI. In the United States, transfer times are consistently long; therefore, many believe a transfer for PCI strategy for STEMI is not practical. Methods and Results-We

CTO PCI is currently being performed with high success and acceptable complication rates among various experienced centers in the United States, Europe, and Russia. (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention [PROGRESS CTO]; NCT02061436).

In CTOs failing standard techniques, use of a new crossing and re-entry system results in a high success rate without increasing complications.
