Percutaneous coronary intervention of anomalous left circumflex coronary artery - A case series

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Surgery

Background:

• Anomalous left circumflex artery (ALCA) is a rare coronary artery anomaly.
• Treatment strategies for symptomatic ALCA can be challenging.
• Percutaneous coronary intervention (PCI) is an alternative to surgical revascularization.

Purpose of the Study:

• To evaluate the efficacy and safety of percutaneous coronary intervention (PCI) for treating anomalous left circumflex artery (ALCA).
• To assess the intermediate-term outcomes of patients who underwent PCI for ALCA.

Main Methods:

• A retrospective case series of 14 patients with ALCA who underwent successful PCI.
• Data collected included patient demographics, procedural details, and clinical outcomes.
• Intermediate-term follow-up was assessed for all patients.

Main Results:

• Successful PCI was achieved in all 14 cases of ALCA.
• The mean patient age was 54.14 years.
• Intermediate-term follow-up (mean 36.0 months) was uneventful in 12 patients; one died of non-cardiac causes, and one was lost to follow-up.

Conclusions:

• Percutaneous coronary intervention (PCI) is a feasible and effective treatment option for anomalous left circumflex artery (ALCA).
• PCI offers a favorable intermediate-term safety profile for ALCA management.
• Further studies are warranted to confirm long-term outcomes.
