Predicting heart pressure from vein size in children
Part of Genetic & congenital, Heart & circulation clinical trials.
This study looks at a possible link between the size of a large vein (the inferior vena cava) and the pressure in the right side of the heart in children. If the link is strong, doctors might one day use vein size to estimate heart pressure without more invasive tests.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 0 and 18 years old.
- You need a central line (a special IV placed in a large vein) as part of your medical care at our center.
- Your parent or guardian has given permission for you to be in the study.
- You do not have a single-ventricle heart condition.
- You have a normal heart rhythm (not a pacemaker rhythm).
- You are not on a breathing machine (ventilator).
- You do not have a blood clot in your inferior vena cava.
- You do not have a condition called isomerism (an organ arrangement issue).

This study uses ultrasound imaging of the heart to check how well the heart valves are working in children who were born with heart defects. It aims to understand valve problems better, which may help guide treatment.
This study examines the health of blood vessels in children ages 6 to 17, using a non-invasive device called Vicorder to measure vessel stiffness. It aims to understand how blood vessel walls work in youth.
This study tests a new, non-invasive way to estimate the pressure inside your child's veins using a blood pressure cuff, aiming to replace the need for frequent invasive measurements. It may help reduce discomfort and risk from catheters.
This study tests if a non-invasive method can estimate central venous pressure, reducing the need for invasive catheters in heart patients.
This trial tests a new way to measure pressure inside a major vein in the chest without needing to stick any needles. It might be an option for children and young adults up to age 21 who already have a central line or are getting a heart catheter.
This study tests if measuring pressure from a vein in the arm can help guide treatment for people hospitalized with worsening heart failure. It aims to understand if this simple procedure could replace or reduce the need for more invasive monitoring.
