Recanalization of an occluded right coronary artery into the right internal mammary artery using a retrograde approach

Area of Science:

• Interventional Cardiology
• Vascular Medicine
• Cardiovascular Interventions

Background:

• Chronic total occlusions (CTO) present significant challenges in interventional cardiology.
• Recanalization of CTOs is crucial for restoring blood flow but often technically demanding.

Observation:

• A case involving a chronically occluded mid-right coronary artery is presented.
• The occlusion was successfully recanalized using a retrograde approach.

Findings:

• The retrograde recanalization was achieved via a septal collateral artery.
• This approach successfully navigated the chronic total occlusion into a right internal mammary graft.

Implications:

• The retrograde approach offers a viable alternative for CTO recanalization.
• This technique expands treatment options for complex coronary artery disease when anterograde methods are unsuccessful.
