Michael Butler,Sylvain Conchon,Fatiha ZaïdiThe principle of counterpulsation is the assistance of a natural heart in series. The device works according to the natural ECG, resulting in a reduction of the systolic pressure and high significant augmentation of the diastolic blood pressure. The augmented diastolic pressure produces significantly better coronary perfusion.

Xiaohong Chen,Ling Yin,Yijun Yu,Zhi JinThe principle of intra-aortic diastolic counterpulsation, first reported by Harken in 1958 [2], was used in 1962 [4] to operate a long intra-aortic air chamber, positioned in the aorta. The intra-aortic balloon is now being widely applied in surgical and medical cases of cardiogenic shock.

Minh Ngo,David A. Naumann,Tamara RezkThe process of the clinical application of the artificial heart is shown in Fig. 1. Patients with cardiogenic shock after cardiac surgery or myocardial infarction are treated with conventional cardiotherapy, e.g., pharmaceutical. If the therapy is not effective, arteriovenous or intra-aortic balloon pumping is indicated.

Systolic Counterpulsation with a Small Balloon to Increase Coronary FlowThe principle of intra-aortic diastolic counterpulsation, first reported by Harken in 1958 [2], was used in 1962 [4] to operate a long intra-aortic air chamber, positioned in the aorta. The intra-aortic balloon is now being widely applied in surgical and medical cases of cardiogenic shock.
