Insights
Coronary artery dissection is a rare complication after aortic valve replacement (AVR). This study highlights methods for identifying and treating this life-threatening condition, emphasizing prompt intervention for better outcomes.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Cardiac Anesthesia
Background:
- Coronary artery dissection is a rare but serious complication during aortic valve replacement (AVR).
- This complication can lead to periprocedural myocardial infarction.
- Accurate identification and timely treatment are crucial for patient survival.
Abstract:
Coronary artery dissection following its cannulation for cardioplegia administration as a result of aortic valve replacement (AVR) is a rare but nevertheless life-threatening complication. The three cases of a patient suffering from aortic stenosis illustrated below focus on the issue of how to identify and treat the dissected artery. In all of the patients who had undergone AVR diagnosed was a periprocedural myocardial infarction. Angiography revealed the dissection of the left main in two of the patients, while in the third one that of the right coronary artery. In the case of local dissection, angiography was sufficient to identify the true lumen, whereas in a dissection encompassing the whole of the coronary tree it was necessary to either find the coronary artery not involved in the dissection or to perform intravascular ultrasound imaging. After true lumen identification, the entry of dissection was stented with the optimal angiographic result.
