Stroke volume (SV) estimation in cardiac ultrasound is a non-invasive method to quantify the amount of blood ejected by the left ventricle with each heartbeat. This critical measurement is fundamental to assessing cardiac function and hemodynamics, often calculated by multiplying the left ventricular outflow tract (LVOT) velocity time integral (VTI) by the LVOT cross-sectional area. It provides valuable insights into the heart’s pumping efficiency, aiding in the diagnosis and management of various cardiovascular conditions.
Accurate stroke volume estimation is crucial for comprehensive cardiovascular assessment in medical ultrasound. By precisely determining the volume of blood pumped per beat, clinicians can evaluate systolic function, monitor therapeutic responses, and identify early signs of cardiac dysfunction. This non-invasive technique enhances diagnostic capabilities, offering vital data for guiding patient care and optimizing treatment strategies in cardiology.
