The effects of pulsatile and nonepulsatile perfusion on cardiac function after open heart surgery were studied in the clinical and experimental materials. Improvement of cardiac function was discussed by cardiac functional curve which was documented every 10 minuts after relicing of aortic cross clamping.
Pulsatile perfusion effected a significant improvement of cardiac function, because of it's diastolic augmentation and unloading of preload. It's maximum effect appeared 20 to 30 minuts after oneset of partial bypass perfusion.
Significant improvement of cardiac function was not recognized in nonepulsatile perfusion.
