Observational Study Evaluating the Management of Chronic Coronary Occlusions In France

Data from the literature on the management of Chronic Coronary Occlusions (CTO) in France highlight a lack of epidemiological data on these patients at the national level. For this reason, it was decided to set up this large-scale survey in order to have a picture of the management of patients with chronic coronary occlusion in France, to study the prevalence of CTOs in France as well as their management (medical, surgical or interventional), and then by analysing more precisely, over a second survey period, CTO angioplasties in terms of success rates, complications, medico-economic impact.
