Percutaneous transluminal coronary angioplasty and stent insertion in a single left coronary artery

Area of Science:

• Cardiology
• Congenital Heart Disease
• Interventional Cardiology

Background:

• Anomalous coronary arteries, particularly single coronary arteries, are rare congenital abnormalities.
• Significant stenoses in these anomalous vessels are infrequently encountered.
• Interventional procedures on single coronary arteries are exceptionally rare.

Observation:

• A patient presented with angina pectoris due to multiple stenotic lesions.
• The patient had a rare anomaly: a single left coronary artery.
• This anatomical variation presented a unique challenge for treatment.

Findings:

• Percutaneous transluminal coronary angioplasty (PTCA) was performed to treat the multiple lesions.
• Intra-coronary stent implantation was successfully employed during the procedure.
• The intervention was technically successful despite the complex coronary anatomy.

Implications:

• This case suggests that complex interventions like multivessel PTCA and stenting can be feasible in single coronary arteries.
• Successful treatment highlights the potential for managing significant stenoses in rare coronary anomalies.
• It expands the understanding of interventional possibilities for patients with single coronary arteries when anatomy permits.
