Ultrasonic backscatter parameters in left ventricular posterior wall and interventricular septum were measured.
Results There were abnormal ventricular movement in all cases, and thinner wall or secondary interventricular septum perforation in part of cases.
Evaluation of respiratory influence on interventricular septum by radius of curvature
Case 4 represents a right-axis deviation (Figure 6), in which the interventricular septum is almost parallel to the anteroposterior line.
AIM To evaluate the influence of pacing in right ventricular septum (RVS) and right ventricular apex (RVA) on pacing parameter and biventricular electrical synchrony.
interventricular septum
Results In 350 cases of VSD,76%(266 caes) were perimembranous types. These defects were variably related to the membranous portion of interventricular septum;
Effect of right ventricular septum pacing and right ventficular apex pacing on cardiac function by tissue Doppler imaging
The anterior descending branch gives off arterial cone, left fringe and anterior interventricular septum branches in proper order.
Experience in the application of active fixation leads in patients with right ventricular septum pacing.
The deep branch (anterior descending branch) gives off arterial cone, left fringe and anterior interventricular septum branches in proper order.
The interventricular septum thickness (IVST), posterior wall thickness , end diastolic diameter of left ventricle and left ventricular mass(LVM) were measured.
The control group: 30 normal subjects who have normal thickness of interventricular septum and left ventricular posterior wall were randomly selected.
Left ventricular flow tract pressure rebounded in 5 patients postoperatively,and neighboring interventricular septum branch extending to melting area were seen in 3 patients accompanied by flow velocity increasing. Melted vessel nub markedly prolonged in 1 patient.
Preoperative management strategy for patients with transposition of the great arteries and intact ventricular septum
The left ventricular weight, the thickness of interventricular septum and the left ventricular posterior wall decreased, too.
