Validation of Peripheral Pressure Volume Loops and Ultrasound-derived "Cardiac Power" by Comparison With Invasive Left Ventricular Pressure Volume Loops

NCT01750450 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 65

Last updated 2014-05-01

No results posted yet for this study

Summary

The investigators will generate pressure-flow loops and pressure-volume loops from aortic and left ventricular pressure waveforms and Doppler (desc. aorta) flow waveforms and compare left ventricular to arterial pressure-flow and pressure-volume loops as well as to cardiac power from the USCOM 1A device. The goal of this study is to test the hypothesis that non-invasive estimates of cardiac pressure-volume work (derived from ultrasound-based measurements) correlate with invasive estimates.
