At the posterior aspect of the heart, the RCA passes through the junction of the interatrial and interventricular septa between the four heart chambers (the crux) and gives rise to up to three small interventricular branches including the PIB (Standring et al.
The interventricular septum should also be evaluated, in cases of overload volume in the right side of the heart the septum is deviated to the left.
Few case reports describe their rare complications including aneurysmal dissection into the muscular interventricular septum with resultant arrhythmias, heart block, (22) and infective endocarditis (23).
Caption: Figure 4: Axial cardiac computed tomography images at the level of the interventricular septum and base of the heart (a) showing fatty infiltration of the right ventricular side of the septum extending into the adjacent trabeculae (red arrow).
The interventricular septum bulges into LV reducing its size and changing its shape from ovoid to crescentic.
Aneurysm of the membranous interventricular septum.
Las alteraciones de la conduccion son secundarias a la presencia de granulomas en los segmentos medio y basal del septo interventricular, ademas del compromiso de la irrigacion de los nodos sinusal y auriculoventricular (AV), lo que genera desde bloqueos de rama hasta bloqueo AV completo.
The thickness of interatrial and interventricular septa of experimental group B1 was more than that of control group A1.
Se inicia el desarrollo del foramen interventricular y se vuelve mas delgado en la linea media.
Debido a mala ventana acustica demostrada en la ecocardiografia transtoracica se realizo ecocardiografia transesofagica, en la que se evidencio movimiento anormal del septum interventricular con desplazamiento del ventriculo izquierdo en diastole, dilatacion biauricular y engrosamiento difuso del pericardio, hallazgos que eran compatibles con pericarditis constrictiva, por lo que fue llevado a estudio hemodinamico prequirurgico donde se evidencio incremento severo de la presion de la auricula derecha; ademas, en la evaluacion del ventriculo derecho, se observo el signo de raiz cuadrada (figura 3).
Each of the studies was based on outcomes of surgical treatment of two groups of pigs (a bypass between the internal thoracic artery and anterior interventricular artery on a beating heart was done).
The dimension of the ventricular chamber is reduced, the interventricular septum thickens, and patients suffer from diastolic dysfunction (in which heart muscle doesn't relax normally), causing an increased risk of sudden death from arrhythmia.
