Insights
Iatrogenic left main coronary artery dissection is a rare complication of coronary catheterization. Surgical repair using an aortic wall patch successfully sealed the intimal tear.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Vascular Medicine
Background:
- Coronary catheterization can lead to rare iatrogenic complications.
- Left main coronary artery (LMCA) dissection and aortic root dissection are significant risks.
Observation:
- A case of catheter-induced LMCA dissection is presented.
- The dissection retrogradely progressed into the ascending aorta wall.
Findings:
- The patient underwent surgical management.
- Ascending aorta replacement and left coronary ostial repair were performed.
- An autologous aortic wall ring-shaped patch was used to seal the intimal tear.
Implications:
- This case highlights a rare but serious complication of coronary catheterization.
- Surgical techniques involving aortic wall patches can effectively manage such dissections.
- Emphasizes the importance of prompt surgical intervention for iatrogenic aortic and coronary artery injuries.
Abstract:
Iatrogenic left main coronary artery and aortic root dissection are rare complications during coronary catheterization. A case of catheter-induced left main coronary artery dissection with subsequent retrograde progression into the ascending aorta wall is reported. The patient was surgically managed with an ascending aorta replacement and left coronary ostial repair with an autologuos aortic wall ring-shaped patch in the paraostial position in order to seal the intimal tear.
