Summary
Coronary artery tortuosity (CAT), a common yet overlooked variant, significantly impacts blood flow and percutaneous coronary intervention (PCI) success. Recognizing CAT early is crucial for better procedural outcomes and fewer complications.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Anatomical Variants
Background:
- Coronary artery tortuosity (CAT) is an anatomical variant affecting coronary blood flow and percutaneous coronary intervention (PCI) outcomes.
- CAT involves bends or loops in coronary vessels, increasing resistance and potentially impairing myocardial perfusion even without obstructive disease.

252
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
