Massive registry to uncover best tactics for Rock-Hard arteries
NCT ID NCT07566403
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This observational study will follow 3000 patients with severely calcified coronary arteries who undergo a procedure to open the blockages (PCI). Researchers will track outcomes like heart attacks and repeat procedures over time. The goal is to learn which techniques work best in everyday practice, especially for high-risk patients often left out of clinical trials.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this registry could provide real-world evidence to guide doctors in choosing the best treatment approach for severely calcified coronary arteries, potentially improving patient outcomes.
- What could go wrong
- This is an observational study, not a controlled trial, so it cannot prove cause and effect. Results may be influenced by patient selection and real-world variability.

Who is studied
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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
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.
