hemodynamic assessment
Measurement of intracardiac pressures and flow parameters during cardiac catheterization.
Full Definition
Hemodynamic assessment involves the direct measurement of pressures, flows, and derived parameters within the cardiac chambers and great vessels during cardiac catheterization procedures. Key measurements include right heart pressures (right atrial, right ventricular, pulmonary arterial, and pulmonary capillary wedge pressures), left heart pressures (left ventricular end-diastolic pressure, aortic pressure), and calculated parameters such as cardiac output, systemic vascular resistance, and transpulmonary gradient. Hemodynamic data provides crucial information about cardiac function, valve disease severity, pulmonary hypertension, and heart failure status. Modern assessment often incorporates advanced techniques including thermodilution cardiac output measurement and instantaneous pressure-volume relationships.
