Radial accEss Crossover for PErcutaneous Coronary Procedures And ouTcome: the REPEAT Study

All patients who undergo to percutaneous coronary diagnostic or interventional procedures through transradial approach (TRA) will be screened for inclusion in this prospective observational study and patients with TRA failure necessitating vascular crossover will be included in the Registry after signing a dedicated written informed consent. A Control group of consecutive patients with radial access and without crossover will be enrolled (2:1 rate compared to crossover group to avoid possible selection bias) after signing a dedicated written informed consent.

The modality of radial puncture (needle vs cannula), the choice of radial sheath (long vs short; hydrophilic vs non hydrophilic), the type of catheters employed, the use of spasmolytic agents and the choice of secondary vascular access will be left to the operator discretion.

According to the selected secondary access, patients will be divided in two groups: patients with a secondary (or tertiary) wrist access (total wrist Group) and patients with a crossover to femoral (Femoral Group). Patients included in the total wrist group may have a secondary access to the ulnar artery (ipsilateral or contralateral) or to the contralateral radial.

All patients will be checked during the procedure, immediately after and 24 hour post to evaluate possible vascular complications and bleeding.

Patient baseline characteristics, hospital data, comorbid conditions and complications will be recorded in a dedicated electronic case report form.
