Severe Coronary Calcification Case Report with LVOT Obstruction

One detailed case report documents a 72-year-old male patient with severe multivessel coronary artery calcification and concomitant hypertrophic cardiomyopathy. The report, authored by Wei Qi and uploaded to figshare in March 2026, describes a multimodal management approach including PCI guided by QFR and IVUS. It details specific clinical metrics like a total CAC score of 1,696 and a reduction in LVOT gradient from 51 mmHg to 9–12 mmHg post-intervention.

Use Cases

• Analyze the relationship between CAC score (1,696) and PCI decision-making for RCA and LCX lesions.
• Study the effect of mavacamten pharmacotherapy on LVOT gradient reduction from 51 mmHg to 9–12 mmHg.
• Review the integration of diagnostic modalities like IVUS and cardiac MRI for managing HCM with segmental fibrosis.
• Examine post-procedural medication protocols, including 6 months of dual antiplatelet therapy followed by aspirin monotherapy.

Strengths

• Single-patient case report with highly detailed clinical narrative and specific metrics.
• Includes precise numerical data points: CAC score of 1,696 and LVOT gradient measurements pre- and post-treatment.
• Documented under the permissive CC-BY-4.0 license for open reuse.

Limitations

• Extremely limited scope with data from only one patient case, preventing statistical analysis.
• No structured columns or sample data provided, limiting machine-readability.
• Temporal coverage is restricted to the timeline of a single patient's treatment.
