Goals
• Exchange experience among the most
experienced;
• Study technologies and strategies,
• Draw information from an own registry,
• Issue ”state of the art” recommendations.
• Teaching courses
Promote angioplasty for treatment of CTO in Europe

AIM
highlight :
• misconceptions in clinical indications,
• outdated technical choices,
• inadequacies in operator training, performance
and centre qualification
• impair the success rates made possible with
contemporary techniques

TRAINING AND CENTRE/OPERATOR COMPETENCY
• how to select appropriately patients for CTO treatment
• experience to avoid common mistakes in recanalisation
• 2 years of training appear sufficient to work as independent primary operator,

EuroCTOEuroCTO Club: Consensus Club: Consensus DocumentDocument
• Complex CTOs require at least experience of 200 CTO cases
• Minimal number of 50 CTOs per year to maintain skills
• Limited number of CTO-operators and ---centres with selection based on workload and audited success and complication rates.
