diastolic augmentation

diastolic augmentation

an increase in arterial diastolic blood pressure produced by a counterpulsation device such as an intraaortic balloon pump. A balloon-tipped catheter positioned in the aorta inflates during ventricular diastole, forcing blood back toward the heart, augmenting diastolic pressure, and assisting coronary artery filling. Balloon deflation at the onset of ventricular systole creates suction in the aorta, thereby assisting ventricular ejection and reducing systolic pressure.

Larger volume balloons displace more blood in the aorta during diastole, resulting in improved diastolic augmentation and systolic unloading.
This analysis concludes that LVD patients who obtain higher diastolic augmentation during EECP treatment receive better short and long-term cardiovascular related outcomes.
With aortic cannulation, the mean aortic pressure is preserved and diastolic augmentation is maintained (4).

group and those in a European cohort, diastolic augmentation remained an independent predictor of clinical outcomes with EECP.
EECP resulted in diastolic augmentation of coronary artery pressure and flow, in addition to systolic unloading of the left ventricle.

The study found that the larger-capacity 50 cc IABPs provides greater diastolic augmentation and systolic unloading compared with the 40 cc IABP.
