NCT01333761

Brief Summary

The CARDIOX Flow Detection System is designed to detect the presence of indocyanine green (ICG) dye in the blood and is being investigated to establish its efficacy in detecting the presence of right to left cardiac shunt (RTLS). The CARDIOX system will be compared against transesophageal echocardiography (TEE) for sensitivity and specificity, as well as transcranial doppler (TCD) for positive percent agreement and negative percent agreement.

Outcome Measures

Primary Outcomes (2)

  • To evaluate the Cardiox FDS system using TCD as a non-reference standard for positive percent agreement for accurately detecting a RTLS and negative percent agreement for accurately detecting the absence of RTLS

    1 day

  • To establish the safety of the Cardiox FDS device by tracking number of participants with adverse events related to Cardiox FDS

    1 day

Secondary Outcomes (1)

  • To evaluate the Cardiox FDS against TEE for sensitivity for the detection of RTLS and specificity for the detecting the absence of a shunt

    1 day

Study Arms (1)

TCD/Cardiox FDS/TEE testing

EXPERIMENTAL

All patients enrolled will be evaluated with TCD and Cardiox FDS and TEE for the presence of RTLS.

Device: Cardiox FDS

Interventions

The Cardiox Shunt Detection system consists of a sensor placed in contact with the outer ear, similar to a finger probe used to detect oxygen levels in blood. Through an intravenous line, ICG (indocyanine green) at a dosage of 10 mg (2 mL of 5 mg/mL ICG solution) per test, is administered into the right or left antecubital fossa. The presence of ICG in the veins within the outer ear are detected, and the results are displayed on a monitor. All patients will also be evaluated with TCD and TEE for the presence of RTLS.

TCD/Cardiox FDS/TEE testing
