UltraTrac for Cardiac Output Monitoring in Congenital Heart Disease

简要摘要

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.
