This pilot feasibility study will evaluate UltraTrac, an investigational noninvasive wearable device for continuous cardiac output monitoring, in patients with congenital heart disease. UltraTrac integrates impedance cardiography and carotid Doppler ultrasound to estimate cardiac output. Participants undergoing clinically indicated cardiac catheterization, cardiac MRI, or cardiac intensive care unit monitoring will have UltraTrac measurements collected during routine clinical care. UltraTrac measurements will be compared with reference standard or clinical hemodynamic measurements, including thermodilution, direct Fick method, cardiac magnetic resonance imaging-derived cardiac output, and clinical hemodynamic assessments before and after vasoactive medication changes. UltraTrac data will not be used to guide clinical decision-making.
Accurate continuous hemodynamic monitoring is important in the management of pediatric and neonatal patients with congenital heart disease, but current monitoring methods may be invasive, intermittent, operator-dependent, or difficult to apply in small pediatric patients. UltraTrac is an investigational wearable hemodynamic monitoring device that integrates impedance cardiography and carotid Doppler ultrasound into a single noninvasive platform. The device uses surface electrodes on the thorax and a wearable Doppler probe positioned over the carotid artery. No vascular access, ionizing radiat…
Inclusion Criteria: * 0-80 years old * Participant weight of at least 2 kg * Diagnosis of congenital heart disease of any anatomic type, including but not limited to repaired or unrepaired single ventricle physiology, biventricular congenital heart disease, valvular disease, septal defects, and conotruncal anomalies * Clinically indicated cardiac catheterization, cardiac MRI, or cardiac intensive care unit admission during the study enrollment period * For Arm 1: scheduled to undergo hemodynamic cardiac catheterization during which thermodilution and/or direct Fick cardiac output measurements…
UltraTrac is an investigational wearable hemodynamic monitoring device that integrates impedance cardiography and carotid Doppler ultrasound into a single noninvasive platform. In this study, UltraTrac will be used only as an observational monitoring device. UltraTrac measurements will not guide clinical decision-making, and all clinical management will proceed according to standard of care.
