The ADRENALINE trial has been designed as a multi-center, prospective randomized study to compare the procedural and periprocedural outcomes of coronary chronic total occlusion (CTO) percutaneous coronary intervention (PCI) using antegrade dissection and re-entry (ADR) versus retrograde strategy. Beyond the patient-oriented outcomes, the influence of the studied CTO PCI strategies on the stress levels among interventional cardiologists will be explored.
The main questions it aims to answer are as follows:
Participants will undergo pre- and postprocedural laboratory testing (cardiac troponin, CK-MB), CMR for late gadolinium enhancement and health status assessment. Subjects undergoing successful CTO PCI using antegrade wiring strategy will be included in the observational arm.
The ADRENALINE trial is planned as a multicenter, prospective randomized research experiment in patients with clinical indication for PCI of CTO. The target population will comprise patients with at least difficult CTO (J-CTO score ≥2) and angiographic equipoise for either ADR or the retrograde CTO recanalization strategy as evaluated by 2 independent CTO PCI operators. The pre-procedural assessment will comprise cardiac magnetic resonance (CMR) for late gadolinium enhancement, laboratory testing (cardiac troponin, creatine kinase-MB) and health status assessed by the Seattle angina questionnaire (SAQ) and the Rose Dyspnea Scale. Subsequently patients with either failed or unattempted primary antegrade wiring strategy will be evenly randomized (1:1 fashion) to either ADR or the retrograde CTO crossing strategy (n=74), while subjects undergoing successful antegrade wiring will be included in the observational arm (n=47). After CTO PCI, the cardiac troponin and creatine kinase-MB will be measured at 12 hours intervals (at least up to 24 hours), while CMR with late gadolinium enhancement will be repeated within 5 days post-procedure (including the observational arm). The health status of the study participants (SAQ and the Rose Dyspnea Scale) will be re-assessed at 3-months post-CTO PCI. In addition, to investigate the effect of the studied CTO PCI strategies on the occupational hazard of interventional cardiologists, the physical and mental stress levels experienced by CTO operators will be continuously monitored during the procedure. The co-primary endpoint is defined as: 1) total procedure time and 2) successful guidewire crossing through CTO. The secondary endpoints include: time of successful guidewire crossing through CTO, final technical success of CTO PCI, radiation dose, contrast volume, equipment cost, procedural complications, rate of periprocedural myocardial injury, rate of new myocardial infarction on CMR, quality of life, target lesion failure (cardiac death, target vessel-related myocardial infarction, and clinically-driven target lesion revascularization) at 3 months follow-up, and stress indices experienced by physicians during the procedure.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| ADR strategy | Other | Patients with either failed or unattempted primary antegrade wiring strategy will be evenly randomized (1:1 fashion) to either ADR or retrograde CTO crossing strategy. The ADR, as part of the antegrade approach, involves extraplaque crossing of the occluded coronary artery with subsequent reentry into the distal true lumen using dedicated reentry systems or knuckle wire techniques. |
|
| Retrograde strategy | Other | Patients with either failed or unattempted primary antegrade wiring strategy will be evenly randomized (1:1 fashion) to either ADR or retrograde CTO crossing strategy. The retrograde technique, planned as the comparator to the ADR strategy, relies on crossing the occluded coronary artery from the distal vessel (i.e. against the original direction of blood flow). Retrograde CTO crossing is attempted either with retrograde intraplaque wiring or more frequently using the retrograde dissection and reentry techniques. |
