Bifurcation Coronary Lesion 0-0-1

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.
