Key result
Ultrasound evaluation demonstrated that 93% of patients without right ventricular volume overload had normal posterior septal motion at or below the level of the chordae tendineae.
Why the study?
What is the normal and abnormal systolic pattern of movement of the interventricular septum in patients with and without right ventricular volume overload?

Refines echocardiographic septal motion criteria; leaves open prospective validation of paradoxical motion in RV volume overload.
Observational (n=398)
What is the normal and abnormal systolic pattern of movement of the interventricular septum in patients with and without right ventricular volume overload?
The study defines the normal pivot point of the interventricular septum during systole and demonstrates that paradoxical septal motion is not universally present in patients with right ventricular volume overload.
Hagan et al. (1974) conducted an observational in Right ventricular volume overload (n=398). Ultrasound evaluation vs. Patients without right ventricular volume overload was evaluated on Septal motion patterns. Ultrasound evaluation demonstrated that 93% of patients without right ventricular volume overload had normal posterior septal motion at or below the level of the chordae tendineae.
