retrograde cardioplegia
Method of delivering cardioplegic solution through the coronary sinus to achieve myocardial protection.
Full Definition
A technique for myocardial protection during cardiac surgery where cardioplegic solution is delivered through the coronary sinus, flowing retrograde through the coronary venous system. This method is particularly useful when there is significant coronary artery disease that might impede antegrade flow, or when aortic regurgitation is present. Anesthesiologists must monitor coronary sinus pressure to prevent injury while ensuring adequate myocardial protection.
Usage
Usage note: Often abbreviated as RCP in clinical documentation.
In Context
- "Due to severe three-vessel disease, retrograde cardioplegia was chosen for optimal myocardial protection." — Operative report
- "Retrograde cardioplegia flow was maintained at 200 mL/min with coronary sinus pressure below 40 mmHg." — Perfusion record
