APPEARANCE 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. 1 and see Video, Supplemental Digital Content 1, which demonstrates characteristic septal bounce on cine SSFP 4-chamber images, http://links.lww.com/JTI/A16). It is accentuated by deep inspiration an...

Increasingly sophisticated echocardiographic procedures are revealing previously unknown details of well known structures such as the interventricular septum.

The blood supply of the interventricular septum has been studied in 43 normal human hearts, from patients dying of noncardiac causes. The specimens were prepared by injection of vinylite into the coronary arteries. Description is made of the normal vascular anatomy of this area, and its clinical importance is discussed. A LTHOUGH the interventricular septum comprises a large portion of the myo-...

In certain instances of left ventricular hypertrophy, deep Q waves observed in the piecordial electrocardiograni miay resemble those of anterior mvocardial infaretion. Such a case is reported in a patient with syphilitic aortic insufficiency. Pathologic examination ruled out the diagnosis of infarction and revealed marked hypertrophy of left ventricular wall and the interventricular septum. The...

Sinus of Valsalva aneurysm (SVA) is an uncommon anomaly of the aorta. Rupture of SVA often precipitates dramatic clinical complications, including heart failures. Right SVAs are the most common type, and when they rupture, they usually rupture into the right ventricle or right atrium. Rupture into left ventricle or interventricular septum is rare. Herein, we report a case of right SVA rupture w...

We report a challenging case of a 81-year-old male with history of severe calcific aortic valve stenosis and aneurysmal membranous interventricular septum. The presence of anomalies in the sub-annular area can lead to valve malpositioning and its consequences. transcatheter aortic valve implantation (TAVR) in patients with aneurysm of the perimembranous interventricular septum extending into th...

Simultaneous recordings of reflected ultrasound from the anterior mitral leaflet and left ventricular outflow, the ECG, the phonocardiogram, and a recording of the carotid artery pulse were obtained in six patients with hypertrophic obstructive cardiomyopathy. Abnormal sharp systolic anterior movement (SAM) of the mitral leaflet was observed. This movement began with the onset of ventricular ej...

Advanced cardiac imaging is a valuable method to investigate cardiac malformations. The detection of the interventricular membranous septum has clinical significance due to thrombogenic and arrythmogenic predisposition, as well as a role in obstructing the pulmonary flow. This review describes six clinical presentations in which advanced cardiac imaging has been the tool for evaluation, with sp...

Cardiac hydatid cysts are rarely seen. The presentation of an acute lower limb ischemia secondary to embolization from an interventricular hydatic cyst is also rare. We describe a case of a 30-year-old-man who presented with acute lower limb ischemia revealing hydatid cyst of the interventricular septum and septal defect, and who was operated on successfully.
