For the understanding of the developmental significance of various parts of the normal ventricular septum, 54 normal human embryos and 154 mature heart specimens showing different types of VSD’s and AV canal malformation were studied. The pars interventriculare of the septum membranaceum is derived primarily from the right superior and inferior tubercies of the AV cushions. The pars atrioventri...

AIM To describe echocardiographically left ventricular false tendon characteristics and the correlation with ventricular repolarization abnormalities in young athletes. METHODS Three hundred and sixteen healthy young athletes from different sport disciplines were evaluated from 2009 to 2011 during routine screening for agonistic sports eligibility. All subjects, as part of standard pre-partic...

The prolate ellipsoid geometry of the left ventricle with normally related great arteries minimizes wall tension and functionally commits the ventricular septum to the systemic ventricle. Ageand pressure-dependent changes in angiographically determined left ventricular volume and mass measurements have been reported in patients with d-transposition of the great arteries and intact interventricu...

In cases with narrow QRS-complex tachycardia, prompt differentiation of the etiology is crucial in management. M-mode echocardiographic examination of the interatrial septum can give important information in the emergency department. A 57-year-old man who had palpitation and dyspnea for 2 days visited our emergency department. The initial ECG showed negative saw-tooth–shaped atrial activity in ...

Methods We compared SSFP four chamber view images (20 phases per cycle protocol) between 11 surgically-confirmed CP patients and 11 controls. We deconvoluted the mechanics of the septal bounce and correlated it with periods of the cardiac cycle. To demonstrate that the septal bounce is caused by the interaction between the tricuspid inflow and septum we constructed a parameter called the septal...

Pulmonic stenosis unassociated with a ventricular septal defect of significant size is often a complex abnormality. The stenosis may be valvular, infundibular, or both, and may be associated with an atrial septal defect or even with a small ventricular septal defect. Preoperative studies cannot accurately predict these variations. The surgical approach selected for such patients should permit t...

Rupture of the infarcted interventricular septum was first described more than a century ago in this country (Latham, 1846). The subject was last reviewed by Fowler and Failey (1948), who discovered 56 recorded cases, of which 16 were diagnosed during life. Since their review, single cases have been described by Sweeny (1948), Bickerman and Irons (1949), Shapir (1949), Ungar and Ullman (1950), ...

When he catheter was pulled back, an iatrogenic ventricular eptal defect (VSD) with a clear left-to-right shunt was etected (Fig. 2, Video 2). TA-AVI was then performed ithout any other complications. One year later the patient as asymptomatic a...

The spread of the excitatory process in the ventricular septum of the dog's heart has been studied in the isolated organ perfused by the Langendorfl technic. It has been possible to remove large portions of the free wall of the right and left ventricles and explore the septal surfaces under direct vision. The mean excitatory pathway in the muscular mass of the dog's ventricular septum has been ...
