Percutaneous Coronary Intervention of Calcified Lesions and the Use of Artificial Intelligence to Predict Successful Outcome

The primary aim of this study is to evaluate changes in absolute coronary flow and pressure before and after percutaneous coronary intervention in calcified lesions. The secondary aim is to use a machine learning model to predict the outcome of the intervention.
