Overview

The OROBICA (Overviewing Real-World Outcomes to Boost Interventional Management of CAlcified Coronary Lesions) Registry is a multicenter, ambispective, real-world observational study designed to evaluate clinical, procedural, imaging, and economic outcomes of patients undergoing percutaneous coronary intervention (PCI) for severely calcified coronary artery disease. Coronary artery calcification represents one of the main determinants of procedural complexity and adverse outcomes in contemporary interventional cardiology. Despite the increasing availability of advanced calcium-modification technologies and intracoronary imaging techniques, evidence regarding the optimal treatment strategy in real-world clinical practice remains limited, particularly among high-risk and complex patients often underrepresented in randomized trials. The OROBICA Registry aims to systematically collect longitudinal data from all-comer patients treated for severely calcified coronary lesions using contemporary PCI strategies, including intracoronary imaging guidance (IVUS/OCT), rotational atherectomy, orbital atherectomy, intravascular lithotripsy, specialty balloons, and combined calcium-modification approaches. The primary objective is to assess clinical and procedural outcomes, with particular focus on target vessel failure (TVF). Secondary and exploratory objectives include evaluation of procedural success, imaging findings, predictors of adverse outcomes, healthcare resource utilization, and economic impact associated with the treatment of calcified coronary lesions. The registry is designed as a flexible research platform intended to support future hypothesis-generating analyses and provide real-world evidence to improve personalized management strategies for calcified coronary artery disease.
