Successful Retrograde Percutaneous Coronary Intervention for Chronic Total Occlusion in a Patient with Dextrocardia

Area of Science:

• Cardiology
• Interventional Cardiology
• Congenital Heart Disease

Background:

• Dextrocardia is a rare congenital condition where the heart is on the right side of the chest.
• Radiographic interpretation and interventional procedures in dextrocardia pose unique challenges due to atypical anatomy.
• Chronic total occlusion (CTO) represents a complex subset of coronary artery disease requiring advanced revascularization strategies.

Observation:

• A case of dextrocardia with a CTO lesion requiring retrograde percutaneous coronary intervention (PCI) is presented.
• Initial angiograms presented significant difficulties in lesion interpretation and device manipulation.
• The double-inversion technique and kissing wire technique were crucial for procedural success.

Findings:

• Retrograde CTO PCI in dextrocardia is technically feasible.
• Specialized techniques like double-inversion and kissing wire are essential for managing complex coronary anatomy in dextrocardia.
• Successful PCI was achieved despite a poor angle of attack, highlighting adaptability.

Implications:

• This case expands the interventional options for patients with dextrocardia and complex coronary artery disease.
• Familiarity with specific angiographic views and advanced techniques can enable successful PCI in rare congenital malpositions.
• Further research into tailored approaches for dextrocardia interventions is warranted.
