Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole.

The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion
