Coronary sinus interventions during cardiac surgery.
There is renewed interest in protecting jeopardized myocardium during regional and global ischemia by coronary sinus retroperfusion. Advances in catheter design and imaging techniques have made access to the coronary sinus easier and safer. Retrograde coronary sinus perfusion, aortovenous bypass, pressure-controlled intermittent coronary sinus occlusion, and synchronized retrograde perfusion have emerged as new techniques by which blood can be redirected through the coronary sinus to nourish ischemic myocardium beyond a coronary occlusion. The purpose of this review is to summarize the current results and applications of these coronary sinus interventions, and show how they can benefit the cardiac surgeon in clinical practice.
