The EPIC registry is an observational multicentre registry evaluating the technical feasibility of retrograde CTO-PCI using epicardial collateral connections. It will evaluate the frequency, effectiveness, safety and outcomes of patients who underwent CTO-PCI using this approach. The EPIC registry retrieves data from CTO centres across Germany.
The EPIC registry is the first German-wide observational multicentre registry evaluating the technical feasibility, clinical success and safety of retrograde CTO-PCI using epicardial collateral connections. The EPIC registry retrieves data from CTO centres across Germany. All patients will be followed-up to 30 days after inclusion.

RECRUITINGRate of technically successful retrograde CTO-PCI using epicaridal collaterals
defined as the rate of successful CTO-PCI with reestablished antegrade coronary flow (thrombolysis in myocardial infarction (TIMI) flow III) with less than residual stenosis of 50%.
Time frame: 30 days
Rate of clinically successful retrograde CTO-PCI using epicaridal collaterals
Clinical success is defined as the rate of successful CTO-PCI by technical success without MACCE and without major periprocedural complications, including pericardial tamponade and contrast induced dialysis.
Time frame: 30 days
Rate of failed retrograde CTO-PCI using epicaridal collaterals
is defined as the rate of CTO-PCI without technical success defined as residual stenosis \>50% (by visual estimation) and TIMI flow grade \<3 after CTO-PCI.
Time frame: 30 days
