Stent Angioplasty in Coronary Artery Anomalies With Intramural Course: When, Why, How, With What Results?

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Imaging

Background:

• Coronary artery anomalies encompass diverse conditions, most with low risk of severe outcomes.
• Identifying patients needing intervention requires accurate risk assessment and diagnostic methods.

Purpose of the Study:

• To delineate which coronary artery anomaly carriers necessitate intervention.
• To review current and novel interventions, focusing on stent angioplasty.
• To propose criteria for defining severe stenosis and optimal risk quantification.

Main Methods:

• Review of nomenclature, anatomical/functional presentations, and diagnostic techniques.
• Detailed description of intravascular ultrasonography-monitored stent angioplasty.
• Reporting initial outcomes from a study of 100 patients with anomalous coronary origin.

Main Results:

• Precise imaging via intravascular ultrasonography or optical coherence tomography is crucial for risk stratification.
• Intravascular ultrasonography-monitored stent angioplasty is a detailed technique for specific anomalies.
• Initial results from 100 patients with anomalous coronary origin are presented.

Conclusions:

• Intervention decisions for coronary artery anomalies should be guided by precise imaging and risk assessment.
• Stent angioplasty, particularly when monitored by intravascular ultrasonography, offers a viable percutaneous option.
• Future multicenter studies are needed to prospectively evaluate stent angioplasty outcomes against surgical results.
