cardioplegic delivery system
The apparatus and tubing used to deliver cardioplegic solution to the myocardium during cardiac surgery for myocardial protection.
Full Definition
A specialized medical device system consisting of tubing, cannulas, and monitoring equipment designed to deliver cardioplegic solution to the coronary circulation or directly to the myocardium during cardiac surgery. The system typically includes pressure monitoring capabilities, temperature control, and may allow for both antegrade and retrograde delivery routes. Modern systems often incorporate safety features such as pressure relief valves and air detection systems to prevent coronary air embolism or excessive pressure delivery that could damage the coronary circulation.
Usage
Usage note: Hyphenate when used as a compound modifier.
