Coronary Plaque Rotational Atherectomy

Coronary plaque rotational atherectomy is a lesion-preparation technique that uses an abrasive rotating burr to modify heavily calcified coronary plaque before balloon angioplasty and stent placement. Its principal value is procedural: improving device passage, lesion expansion, and stent delivery when conventional balloon-based strategies are inadequate. Use is generally determined by anatomy, calcium burden, vessel characteristics, operator expertise, and availability of complementary imaging and support technologies.

Treatment is shifting from an isolated device choice toward an imaging-led, algorithmic approach to calcium modification. Intravascular ultrasound and optical coherence tomography help characterize calcium distribution, thickness, length, and fracture patterns, while newer specialty balloons, intravascular lithotripsy, orbital atherectomy, and laser technologies broaden the procedural toolkit. Rotational atherectomy remains particularly relevant when lesions are severely calcified, balloon-uncrossable, or resistant to balloon expansion, but contemporary practice emphasizes careful patient selection and staged escalation.

Artificial intelligence can support coronary calcium assessment by assisting image interpretation, identifying high-risk lesion features, and standardizing measurements across imaging studies. It may also help integrate angiographic, intravascular imaging, electrocardiographic, and clinical data to support procedural planning and post-procedure quality review. These applications remain dependent on representative training data, prospective validation, workflow integration, cybersecurity, and regulatory oversight; AI should therefore augment rather than replace specialist judgment.

North America and Europe generally benefit from established interventional cardiology networks, advanced imaging access, and structured training, supporting use in complex calcified lesions. Asia-Pacific combines expanding cardiovascular intervention capacity with substantial variation between urban referral centers and lower-resource settings. Latin America is characterized by unequal access to specialized equipment, reimbursement, and high-volume operators. The Middle East has concentrated advanced cardiac services in major centers, while Africa faces wider constraints in diagnostic infrastructure, device availability, maintenance, and specialist coverage. Across all regions, reliable imaging, complication-management capability, and training are central determinants of safe use.

ASEAN markets show varied interventional capacity and healthcare financing, with advanced services concentrated in selected metropolitan hospitals. BRICS countries combine large cardiovascular-care needs with major differences in procurement, reimbursement, domestic manufacturing, and specialist distribution. The European Union benefits from cross-border clinical knowledge exchange while retaining national differences in access and payment. G7 systems generally possess mature catheterization infrastructure but face cost-effectiveness and workforce pressures. GCC countries have concentrated investment in advanced hospitals, whereas NATO members span highly diverse healthcare systems, procurement models, and clinical-training environments.

Australia, Canada, France, Germany, Italy, Japan, South Korea, Spain, the United Kingdom, and the United States have established interventional cardiology capabilities, although access, reimbursement, imaging availability, and regional workforce distribution differ. China and India combine substantial clinical demand with rapidly expanding and unevenly distributed cardiac-care capacity. Brazil and Mexico show strong activity in leading centers alongside public- and private-sector access differences. Russia’s availability is shaped by institutional capacity, procurement conditions, and broader health-system constraints. Across these countries, adoption depends less on plaque prevalence alone than on referral pathways, operator training, imaging access, and the ability to manage perforation, slow flow, and other complications.

Industry leaders should define clear lesion-selection protocols that position rotational atherectomy within a broader calcium-modification algorithm. Programs should pair appropriate intravascular imaging with structured simulation, proctoring, credentialing, and complication-readiness drills. Hospitals can improve value by tracking crossing success, stent expansion, radiation exposure, contrast use, complications, and repeat intervention, while aligning procurement with demonstrated clinical need. Manufacturers and health systems should support interoperable data, transparent post-market surveillance, and training models that extend expertise beyond a small number of high-volume centers.

This executive summary synthesizes established clinical principles and publicly documented evidence concerning coronary calcification, percutaneous coronary intervention, plaque-modification techniques, intravascular imaging, artificial intelligence, healthcare capacity, and regional delivery conditions. Interpretation emphasizes guideline and consensus themes, peer-reviewed clinical research, regulatory and safety considerations, and observable differences in infrastructure and training. No market estimates, forecasts, market shares, or company-specific assessments are used. Regional, group, and country observations are framed as qualitative system-level insights rather than quantitative rankings.

Rotational atherectomy remains a specialized option for complex coronary calcification, particularly when lesions cannot be adequately crossed or expanded with conventional methods. Its role is being reshaped by intravascular imaging, complementary plaque-modification technologies, improved training, and data-supported decision-making. Sustainable clinical value will depend on selecting appropriate patients, applying disciplined procedural technique, ensuring access to rescue capabilities, and embedding the technology within coordinated, evidence-based cardiac-care pathways.
