Background:

• The current utility of the American College of Cardiology/American Heart Association (ACC/AHA) classification system for coronary lesions in reflecting medical resource consumption during percutaneous coronary interventions (PCI) remains unclear.
• Understanding this relationship is crucial for optimizing resource allocation and cost-effectiveness in cardiovascular procedures.

Purpose of the Study:

• To investigate the association between the ACC/AHA classification of coronary artery lesions and the utilization of medical resources during PCI.
• To determine if lesion complexity, as defined by the ACC/AHA system, correlates with procedural costs, contrast volume, and fluoroscopy time.

Main Methods:

• A retrospective analysis of 447 coronary artery lesions treated with PCI between January 1, 2009, and December 31, 2009, was conducted.
• Lesions were categorized into Type A, B1, B2, and C according to ACC/AHA criteria.
• Total PCI costs, contrast volumes, and fluoroscopy times were compared across these lesion types.

Main Results:

• A significant correlation was observed between ACC/AHA lesion type and medical resource utilization (P < 0.0001).
• Total PCI costs, contrast volumes, and fluoroscopy times increased progressively from Type A to Type C lesions.
• Specifically, average PCI costs ranged from $7,262 for Type A to $13,243 for Type C lesions.

Conclusions:

• The ACC/AHA lesion classification system serves as a reliable indicator of medical resource consumption in contemporary PCI.
• Complex coronary lesions (Type C) are associated with substantially higher costs, contrast use, and fluoroscopy times compared to simpler lesions (Type A).
• This stratification has implications for procedural planning, cost-effectiveness analyses, and resource management in interventional cardiology.
