Contemporary outcomes of chronic total occlusion percutaneous coronary intervention in Europe: the European Registry of Chronic Total Occlusion (ERCTO) registry
Authors' conclusion
The adoption of different recanalisation techniques, operator experience and the use of specific devices have contributed to a high procedural success rate despite the high complexity of the lesions documented in the ERCTO.
