How to measure LVOT VTI : A step-by-step approach you MUST know | Echocardiography | 2025

In this video we are going to show you how to measure LVOT VTI in a step-by-step systematic approach.

Learn how to measure LVOT VTI step-by-step using POCUS echocardiography to assess stroke volume and cardiac output in critically ill patients. This LVOT VTI tutorial demonstrates pulse wave Doppler in the apical 5-chamber view, LVOT diameter measurement, waveform tracing, and Doppler troubleshooting - perfect for Emergency, ICU, and Advanced Echo learners.

In this video, we cover:
✔ LVOT VTI measurement technique on echo/POCUS
✔ Proper LVOT VTI gate placement
✔ Optimising Doppler ultrasound alignment
✔ LVOT VTI normal values and interpretation
✔ Using VTI for hemodynamics, shock ultrasound, and fluid responsiveness
✔ Stroke volume calculation and cardiac output estimation
✔ Common LVOT VTI Doppler troubleshooting errors to avoid
✔ When LVOT VTI is useful in the intensive care unit (ICU echocardiography) and emergency settings

LVOT VTI gives real-time insights into cardiac output and heart rate relationships and helps guide resuscitation in shock. Whether you are learning critical care echo, advanced echo skills, or improving your ultrasound training, this video will enhance your confidence in point of care ultrasound assessment.
