Septal bounce

Case contributed by Dr Matt A. Morgan

Presentation

Evaluate for possible constrictive pericarditis.

Patient Data

Age: 55Y
Gender: Male

Septal bounce

Modality: MRI

The septum demonstrates abnormal movement with each cardiac cycle, termed a "bounce."

In these images, the pericardium is thickened, compatible with a diagnosis of constrictive pericarditis.

Case Discussion

"Septal bounce" is a sign of ventricular interdependence.  When the ventricles are constricted (e.g. tethered by the pericardium), the motion of the ventricular walls is markedly reduced and the volume of the heart is fixed. Changes in ventricular volumes and pressures are then reflected through deviations of the septum.
