Rescue PTCA in a Patient with Single Coronary Anomaly

Area of Science:

• Cardiology
• Interventional Cardiology
• Congenital Heart Disease

Background:

• Single coronary artery is a rare congenital anomaly.
• Atherosclerotic stenosis in anomalous coronary arteries presents unique challenges for treatment.
• Percutaneous coronary intervention (PCI) in single coronary artery anomalies is infrequently reported.

Observation:

• A patient presented with a rare single coronary artery originating from the right sinus.
• The patient required rescue percutaneous coronary intervention (PCI) for atherosclerotic lesions.
• The PCI procedure was performed using a right radial artery approach.

Findings:

• Successful rescue PCI was achieved using the right radial approach.
• The case highlights the feasibility of PCI in managing atherosclerotic disease in a single coronary artery.
• Technical difficulties related to ostial configuration and catheter manipulation were managed.

Implications:

• This case expands the understanding of interventional treatment options for single coronary artery anomalies.
• It demonstrates the safety and efficacy of the right radial approach in complex PCI scenarios.
• Further research may explore optimal PCI strategies for these rare anatomical variations.
