Summary

The study aims to standardize patient positioning during bedside ultrasound assessment of internal jugular vein (IJV) and correlate the results with invasive hemodynamics obtained immediately after. The study hypothesizes that the respiratory variation in the size of IJV, as estimated through ultrasound at bedside, is an accurate estimation of the patient's actual right atrial pressure estimated through right heart catheterization.

Conditions

• Catheterization

Interventions

Type	Name	Description
DEVICE	Ultrasound imaging	Patients scheduled to undergo right heart catheterization (RHC) as their standard of care will be included in the study. The patient will be positioned supine at 0 degrees with normal restful breathing and patient looking straight up. After the right sternocleidomastoid muscle is identified, internal jugular vein (IJV) will be imaged at the apex of the triangle formed by the sternal and clavicular heads of the muscle. Similarly, the inferior vena cava (IVC) will be imaged at the caudal end of the sternum. The diameters of both the veins will be noted during normal respiration. The patients will then be asked to sniff and collapsibility of the veins will be noted. No pressure will be applied on the neck. The anticipated duration for image acquisition is between 5 to 10 minutes. The patients will undergo the scheduled RHC within 1 hour as scheduled.
