Rescue percutaneous coronary recanalization of right coronary artery by retrograde approach

Area of Science:

• Cardiology
• Interventional Cardiology

Background:

• Chronic total occlusion (CTO) of the right coronary artery (RCA) presents a challenge in interventional cardiology.
• Collateral circulation is crucial for managing ischemia during complex coronary interventions.

Observation:

• During an attempted opening of RCA CTO, a 62-year-old female patient developed collateral occlusion.
• This complication led to acute inferior wall ischemia, indicating a critical blood flow compromise.

Findings:

• A successful rescue percutaneous coronary intervention (PCI) was performed utilizing a retrograde approach.
• This retrograde PCI strategy effectively restored blood flow and prevented myocardial infarction.

Implications:

• The retrograde approach is a viable and effective strategy for complex PCI cases, particularly when antegrade attempts fail or lead to complications.
• This case highlights the importance of considering alternative PCI techniques to manage challenging coronary artery occlusions and prevent adverse cardiac events.
