A 31-year-old woman experienced chest pain due to coronary artery constriction. This case highlights a rare finding of coronary artery bridges diagnosed via cineangiocoronariography.

Area of Science:

  • Cardiology
  • Cardiovascular Medicine
  • Medical Diagnostics

Background:

  • Coronary artery disease (CAD) can manifest with diverse symptoms, often necessitating advanced imaging for accurate diagnosis.
  • Myocardial bridges are a congenital anomaly where a segment of a coronary artery travels through the heart muscle, potentially causing ischemia.

Observation:

  • A 31-year-old female presented with exertional dyspnea, diaphoresis, and dizziness, alongside precordial pain and left arm discomfort.
  • Symptoms resolved spontaneously, but daily precordial pain persisted, prompting further investigation.

Findings:

  • Cineangiocoronariography revealed 100% constriction of the left descending coronary artery during systole.
  • Constriction was also noted in the diagonal and marginal branches, indicative of significant dynamic obstruction.

  • This case represents a unique presentation of coronary artery bridges diagnosed during a diagnostic angiography.

    • Implications:

    • This case underscores the importance of considering dynamic coronary obstruction in young patients presenting with cardiac symptoms.
    • Diagnostic angiography is crucial for identifying anatomical abnormalities like coronary artery bridges that may not be apparent otherwise.
    • Further research into the long-term implications and management strategies for symptomatic coronary artery bridges is warranted.
