aortic root venting
Placement of a catheter or needle in the aortic root to remove air and blood during cardiac procedures.
Full Definition
A technique used during open heart surgery to prevent air embolism and maintain visualization of the operative field. The vent, typically placed through the ascending aorta or non-coronary sinus, continuously removes air that enters the left heart during valve procedures or other cardiac manipulations. Proper venting is critical for preventing cerebral and coronary air embolism when the heart resumes beating.
Usage
Usage note: Often confused with aortic cannulation, which serves a different purpose.
