Efficacy of systolic vs diastolic pulsation beyond severe coronary stenosis flow.
This paper describes the superiority of systolic pulsatile selective coronary perfusion as compared to diastolic pulsatile coronary perfusion in improving flow beyond ischemia-producing coronary artery obstructions in the working heart. The practical implications for use in coronary support perfusion systems are discussed.
