Abstract
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 special emphasis in CT angiography and cardiac MRI sequences. Teaching Points • The interventricular membranous septum can predispose patients to thrombogenic and arrythmogenic events. • Subpulmonic stenosis relates to the protrusion of the aneurysm into the right ventricle • During surgery, ventricular pressures of the opened heart become balanced, making the aneurysm less evident.
摘要
先进的心脏成像技术是研究心脏畸形的一种有价值的方法。室间隔膜部的检测具有临床意义，因为它具有血栓形成和致心律失常的易感性，以及在阻碍肺血流方面的作用。本综述描述了六种临床表现，其中先进的心脏成像技术已成为评估工具，特别强调了CT血管造影和心脏MRI序列。教学要点 • 室间隔膜部可使患者易发生血栓形成和致心律失常事件。 • 肺动脉瓣下狭窄与动脉瘤突入右心室有关 • 在手术过程中，开放心脏的心室压力变得平衡，使动脉瘤不那么明显。
