aortic root cannula
Specialized tube inserted into the aortic root to deliver cardioplegic solution during cardiac surgery.
Full Definition
A specialized cannula placed directly into the aortic root to provide antegrade delivery of cardioplegic solution to the coronary arteries. This technique ensures uniform distribution of cardioprotective solution during cardiac arrest. Proper placement is critical for myocardial protection, and anesthesiologists must monitor for complications such as aortic dissection or coronary ostial injury during insertion.
Usage
Usage note: Distinguish from general aortic cannulation used for arterial return during cardiopulmonary bypass.
