Overviewing Real-World Outcomes to Boost Interventional Management of CAlcified Coronary Lesions: the OROBICA Registry. (OROBICA)

May 4, 2026 updated by: Francesco Moretti, Papa Giovanni XXIII Hospital

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The OROBICA Registry will include adult patients undergoing percutaneous coronary intervention (PCI) for severely calcified coronary artery disease in routine clinical practice. The study population consists of all-comer patients treated for complex calcified coronary lesions, including individuals with stable coronary artery disease, acute coronary syndromes, multivessel disease, left main disease, bifurcation lesions, chronic total occlusions, and high-risk clinical or anatomical features.

Description

Inclusion Criteria:

  • Patients undergoing percutaneous coronary intervention (PCI) for severely calcified coronary lesions, angiographically defined as radiopacities noted without cardiac motion before contrast injection, generally involving both sides of the arterial wall.

  • Patients undergoing PCI for calcified coronary lesions with intracoronary optical coherence tomography (OCT) showing at least one of the following features:

    • calcium arc ≥180°
    • calcium thickness ≥0.3 mm
    • calcium length ≥3 mm
    • presence of calcified nodules

  • Patients undergoing PCI for calcified coronary lesions with intravascular ultrasound (IVUS) showing at least one of the following features:

    • calcium arc ≥180°
    • concentric or superficial calcium with extensive acoustic shadowing
    • presence of calcified nodules

Exclusion Criteria:

  • Lack of availability of essential clinical or procedural data.
  • Refusal or withdrawal of informed consent for the prospective component of the registry, when applicable.
  • Exercise of the right to object to data processing, according to applicable data protection regulations.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rate of Target Vessel Failure (TVF)
Time Frame: 1, 2 and 5 years
Defined as composite of Cardiac Death, Target vessel Myocardial Infarction and Clinically-Driven Target Vessel Revascularization
1, 2 and 5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Rate of Major Adverse Cardiovascular Events (MACE)
Time Frame: 1, 2 and 5 years
Defined as composite of all-cause death, myocardial infarction (MI), stroke, clinically-driven target vessel revascularisation (CD-TVR) and hospitalization for cardiovascular causes

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
