Experimental and clinical evaluation of a counterpulsation device.
The counterpulsation technique has been widely used for the assistance of the acutely failing left ventricle utilizing the intraaortic balloon pump. However, a variety of other counterpulsation devices are available. To evaluate a counterpulsation device several variables need to be considered: (1) experimental and clinical determination of the salutary effects of the device on the left ventricular ejection fraction, cardiac output, aortic pressures, left ventricular end-diastolic pressure, tension-time index, diastolic pressure-time index and endocardial viability ratio; (2) experimental and clinical estimation of the device biocompatibility, and (3) the clinical improvement of the assisted patients.
