counterpulsation

counterpulsation
A means of assisting the failing heart by automatically removing arterial blood just before and during ventricular ejection and returning it to the circulation during diastole; a balloon catheter is inserted into the aorta and activated by an automatic mechanism triggered by the ECG.
- intra- aortic balloon c. rhythmic inflation and deflation of a catheter-borne balloon placed in the aorta distal to the aortic valve to facilitate ejection during systole and to limit regurgitation during diastole by the appropriate application of pressures. Usually an emergency treatment for cardiogenic shock or for intractable angina.
