Insights
This case study details a percutaneous coronary intervention for a blocked left circumflex artery. The procedure utilized collateral circulation from the left anterior descending artery to treat the chronic total occlusion.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Biology
Background:
- Coronary artery disease (CAD) remains a leading cause of mortality worldwide.
- Chronic total occlusions (CTOs) present unique challenges in revascularization.
- Percutaneous coronary intervention (PCI) is a primary treatment modality for CTOs.
Abstract:
A 60-year-old man was referred for percutaneous coronary intervention of a proximal left circumflex (Cx) chronic total occlusion (CTO) with distal filling via epicardial collaterals from the left anterior descending (LAD) artery.
