What does septal bounce mean?
Septal bounce is a sign of ventricular interdependence on echocardiography, cardiac CT, and cardiac MRI, manifested by paradoxical interventricular septal movement during early diastole (i.e. initial septal movement towards and then away from the left ventricle) seen mainly in constrictive pericarditis and occasionally …
What causes septal bounce on Echo?
Explanation: The septal bounce is typically seen in constrictive pericarditis and cardiac tamponade when there is an increase in ventricular interdependence. Ventricular interdependence occurs in conditions where an increase in volume of one ventricle causes a decreased volume in the opposite ventricle.
What causes septal motion?
During diastole, the septum acts as a compliant membrane between the two ventricles, and its position and geometry respond to even small alterations in the trans-septal pressure gradients. Abnormal septal motion can be caused by an overload of the right ventricle, delayed ventricular filling and abnormal conduction.
What is septal dyskinesia?
Septal dyskinesia was defined as either paradoxical septal motion or stretching of the segmental wall during systole. Six patients with septal dyskinesia and LV dysfunction underwent more sophisticated echocardiographic examinations both before and after RFA.
What is septal flattening?
The most prominent features of severe pulmonary hypertension are dilatation of the right ventricle and systolic “flattening” of the interventricular septum. Flattening of the IVS is the result of high pressure in the right ventricle, which exceeds that of the left ventricle during systole.
Is paradoxical septal motion normal?
Normal Septal Motion Interrogated with M-mode Imaging. A multitude of disorders can create an abnormal, paradoxical septal motion, often referred to as ‘septal bounce’, where the interventricular septum movement is atypical for the particular phase of the cardiac cycle.
What is the septal wall?
The septum is the wall of tissue that separates the right ventricle of your heart from the left ventricle. Septal infarct is also called septal infarction. Septal infarct is usually caused by an inadequate blood supply during a heart attack (myocardial infarction).
Which is an example of a paradoxical septal movement?
A multitude of disorders can create an abnormal, paradoxical septal motion, often referred to as ‘septal bounce’, where the interventricular septum movement is atypical for the particular phase of the cardiac cycle.
Are there any early diastolic sounds associated with septal motion?
Described herein is a new early diastolic sound observed in four patient’s with paradoxical septal motion and dilated right ventricles. In each patient the atrioventricular valves and transvalvular flow rates were normal, and the sound appeared to result from the markedly abnormal septal motion.
What causes abnormal septal motion or septal bounce?
Causes of abnormal septal motion or septal bounce Cardiac conditions Left bundle branch block ‘Open’ cardiac Pulmonary-related conditions Increase right ventricle afterload Pulmo Others Right ventricle volume overload
What kind of constriction does the septum have?
In mild and moderate constriction, only the single motion of the septum in early diastole is noted, that of the exaggerated septal shift with inspiration.
