What is a septal bounce?

Appearance: The septal bounce is a paradoxical bouncing motion of the interventricular septum initially directed towards and then away from the left ventricle during early diastole (Fig.

Is septal bounce normal?

There are reports in the echocardiography literature of the septal bounce being seen in normal patients and in patients with restrictive cardiomyopathy.

What is the difference between constrictive pericarditis and restrictive cardiomyopathy?

In restrictive cardiomyopathy, reduced compliance is caused by abnormal elastic properties of the myocardium and/or intercellular matrix, whereas in constrictive pericarditis, reduced chamber compliance is imposed by the external pericardial constraint.

Why does paradoxical septal motion occur?

The paradoxical septal motion in patients with atrial septal defect (ASD) occurs due to right ventricular volume overload (10). In these patients, the degree of septal paradoxical motion is significantly related to the degree of volume overload.

What is abnormal septal motion?

Abnormal septal motion (ASM), or septal bouncing, is a paradoxical bouncing motion of the interventricular septum. 1) During early diastolic period, interventricular septum initially directed towards and moves away from the left ventricle. ASM can be found frequently during echocardiographic examinations.

What does a pericardial knock sound like?

The pericardial knock is a high-pitched, early diastolic sound that occurs when unyielding pericardium results in sudden arrest of ventricular filling. It can be an important clue to the diagnosis of constrictive pericarditis.

What is atypical septal motion?

Abnormal septal motion (ASM), or septal bouncing, is a paradoxical bouncing motion of the interventricular septum. 1) During early diastolic period, interventricular septum initially directed towards and moves away from the left ventricle.

What are the three types of cardiomyopathy?

The main types of cardiomyopathy include dilated, hypertrophic and restrictive cardiomyopathy. Treatment — which might include medications, surgically implanted devices, heart surgery or, in severe cases, a heart transplant — depends on which type of cardiomyopathy you have and how serious it is.

Is pericarditis self limiting?

Acute pericarditis is usually a benign self-limiting condition, often of unexplained or viral aetiology, involving inflammation of the pericardial layers.

What is jerky septal motion?

Presence of LBBB gives the septum a jerky movement on echocardiogram. This abnormal movement of the septum is just indicative of underlying LBBB and does not specify any heart disease. Presence or absence of heart disease is typically based on the results of echocardiogram, coronary angiography and/or cardiac MRI.

What does septal bounce mean in cardiology?

Septal bounce is a specific and relatively sensitive sign of ventricular interdependence due to constrictive pericarditis and is considered a reliable sign to distinguish constrictive pericarditis from restrictive cardiomyopathy.

Septal bounce is a specific and relatively sensitive sign of ventricular interdependence due to constrictive pericarditis and is considered a reliable sign to distinguish constrictive pericarditis from restrictive cardiomyopathy. 1. Walker CM, Chung JH, Reddy GP.
