Successful CTO-PCI

Description:

Success was defined as a procedure achieving a final residual stenosis \< 30% (by visual estimation) and a TIMI flow grade 3 after CTO recanalization in all living patients within 24h following angioplasty.

Treatment:

Other: Percutaneous Coronary Intervention of CTO

Failed CTO-PCI

Description:

Success was defined as a procedure achieving a final residual stenosis \< 30% (by visual estimation) and a TIMI flow grade 3 after CTO recanalization in all living patients within 24h following angioplasty.
