Transradial Coronary Intervention in Chronic Total Occlusion in a Patient With Mirror Image Dextrocardia

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Imaging

Background:

• Dextrocardia, a congenital condition where the heart is on the right side of the chest, presents unique anatomical challenges for cardiovascular procedures.
• Percutaneous coronary intervention (PCI) in patients with dextrocardia, especially with coexisting coronary artery anomalies or occlusions, requires specialized approaches.
• Chronic total occlusions (CTOs) in coronary arteries are complex lesions that demand advanced techniques and careful planning for successful revascularization.

Observation:

• This report details a successful PCI of a CTO in the left anterior descending artery (LAD) in a patient with situs inversus and dextrocardia.
• The intervention was performed using a right radial artery access, a less common approach in dextrocardia due to altered anatomy.
• Technical difficulties included managing unfamiliar coronary artery orientations and ensuring guide catheter stability during hardware manipulation across the CTO.

Findings:

• The trans-radial PCI approach was demonstrated to be safe and feasible even in complex dextrocardia anatomy with CTO.
• Successful recanalization of the LAD CTO was achieved using meticulous pre-planned imaging strategies and judicious selection of interventional hardware.
• The case highlights the importance of adapting standard PCI techniques to the specific anatomical variations presented by dextrocardia.

Implications:

• This successful intervention suggests that trans-radial PCI can be a viable option for managing coronary artery disease in patients with dextrocardia and CTO.
• Effective management relies on thorough pre-procedural planning, including advanced imaging, and the use of specialized equipment to navigate complex anatomy.
• Further studies and case reports are warranted to build a robust evidence base for PCI in this patient population, potentially improving outcomes and expanding treatment options.
