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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: IABP recipient
Referred for clinically indicated right heart catheterization with intervention of IABP placement prior to LVAD surgery.
CD Leycom Conductance Catheter
Experimental: Control
Control subjects undergoing left heart catheterization with an LV ejection fraction > 50%, and without a history of heart failure symptoms who did not receive IABP therapy were enrolled.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
