Treatment optimization of aortocoronary dissection as a complication after heart catheterization using coronary...

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Vascular Surgery

Background:

• Coronary artery interventions carry risks, including rare but serious complications like aortic dissection.
• Chronic total occlusions present unique challenges during percutaneous coronary intervention.
• Retrograde aortic dissection following coronary intervention is an uncommon but critical event.

Observation:

• A 71-year-old patient developed retrograde aortic dissection after right coronary artery intervention for chronic total occlusion.
• Initial management involved stenting the proximal right coronary artery to seal the dissection entry.
• Computed tomography angiography revealed progression of the intramural aortic hematoma and residual dissection at the ostium.

Findings:

• A second coronary angiography and stent implantation successfully covered the dissection entry at the right coronary artery ostium.
• Follow-up imaging confirmed complete coverage of the dissection and significant regression of the intramural aortic hematoma.
• The dual-stenting strategy effectively managed this complex iatrogenic aortic injury.

Implications:

• This case highlights the importance of prompt diagnosis and tailored endovascular management for iatrogenic aortic dissections.
• Successful treatment with stenting demonstrates a viable therapeutic option for this rare complication.
• Further research into preventative strategies and optimal management algorithms for dissection during coronary interventions is warranted.
