An 80-year-old man with non-ST-elevation acute coronary syndrome (NSTEACS) successfully recovered after percutaneous coronary intervention (PCI) for a left anterior descending artery lesion. Coronary artery anomalies, though rare, often require conservative management, as demonstrated in this case.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Biology

Background:

  • Non-ST-elevation acute coronary syndrome (NSTEACS) requires prompt diagnosis and management.
  • Coronary artery anomalies occur in approximately 1% of the population, with the right coronary artery (RCA) being the most frequently affected.
  • Percutaneous coronary intervention (PCI) is a standard treatment for significant coronary artery stenosis.

Observation:

  • An 80-year-old gentleman presented with NSTEACS, evidenced by anterior T-wave inversion and elevated Troponin T.
  • Coronary angiography revealed stenosis in the proximal left anterior descending (LAD) artery, necessitating PCI.
  • A large RCA with significant collateralization to the pulmonary artery (PA) was noted but not intervened upon.

Findings:

Related Experiment Videos

  • The patient underwent successful PCI of the LAD lesion.
  • The patient experienced a favorable recovery and remained asymptomatic for over two years post-procedure.
  • The large RCA with collateral circulation did not require intervention, suggesting a benign clinical course.

    • Implications:

    • This case highlights the importance of individualized treatment strategies for coronary artery anomalies.
    • Conservative management may be appropriate for certain coronary artery anomalies, particularly when asymptomatic or with significant collateralization.
    • Further research into the long-term outcomes of coronary artery anomalies and their optimal management is warranted.
