Clinical Hemodynamic Study of Balloon Counterpulsation in Advanced Heart Failure
April 25, 2017 updated by: Tufts Medical Center
The primary objective of this study is to develop normative hemodynamic data (means and standard deviations) for the intra-aortic balloon pump (IABP) using pressure-volume loop and 3D-echocardiographic analyses.

---|---|---|
Impact of Intra-aortic Balloon Pump Activation on Left Ventricular Stroke Work.
Time Frame: 24 hours
|
We will be measuring left ventricular stroke work using a conductance catheter before and immediately after activation of an intra-aortic balloon pump (IABP).
Left ventricular stroke work is quantified as the product of left ventricular pressure and volume.
Conductance catheters are the primary method available for clinical measurement of left ventricular volume and pressure.
