Brief Summary: Research Involving Human Persons RIHP 3 focusing on the treatment of type 0-0-1 bifurcation lesions in routine practice Multicenter Study
To retrieve and analyze the details of different angioplasty techniques used in this type of bifurcation lesion Medina 0-0-1 in order to describe current practice and search for predictors of clinical events
Detailed Description: The primary objective of the trial is to estimate the frequency of Major Adverse Cardiac Events MACE including cardiac death myocardial infarction within the territory of the treated lesion and revascularization of the target lesion in a representative population of patients treated by coronary angioplasty of type 0-0-1 bifurcation lesions
The sample size will be determined by the number of angioplasties of type 0-0-1 bifurcation lesions performed at each center between 2016 and 2022
Since the trial is observational in nature and there are no previously published studies the sample size cannot be calculated based on the desired precision of the estimation
Furthermore the purpose of the study is also to assess the techniques used to treat this type of coronary bifurcation and to highlight any differences between different centers and with other types of coronary bifurcation lesions described in the literature
