Summary

Currently, in order to visualize the inferior vena cava (IVC) of the heart using ultrasound, physicians traditionally place the ultrasound probe onto the "Subcostal" area which is located below the chest in the upper abdomen area. In this location, the pressure from the ultrasound probe is often uncomfortable for adults, and even more so for pediatric patients. Previous research and physician experience have demonstrated that it is possible to visualize the heart in the "transhepatic" area which is located under the arm on the side of the chest. By placing the ultrasound probe in this location, it is more comfortable for the patient when applying pressure, and this study aims to prove the effectiveness of visualizing the heart through this new location.

Conditions

• Inferior Vena Cava Abnormality

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Ultrasound Analysis of Inferior Vena Cavae (IVC)	Novel Operators will attempt to visualize the Inferior Vena Cavae through two different views on the patient's body. The images taken will be interpreted by an expert ultrasound user to determine if the novel operator was successful in locating and evaluating the IVC.
