Novel Multi-Modality Assessment of Arrhythmic Risk and Disease Progression in Repaired Tetralogy of Fallot Undergoing Redo-Pulmonary Valve Surgery Using 4D Cardiac MRI Flow and High Density 3D Electro-Anatomical Mapping.

心律失常猝死是法洛四联症成人最常见的死亡原因，法洛四联症是一种先天性心脏病。已经证明，当存在严重的肺瓣膜疾病时，几乎一半的患者可以诱发危险的心律失常。我们的研究将使用MRI和电生理测试来评估肺动脉瓣手术前后发生心律失常的可能性，以确定这些患者是否需要除颤器。

Sudden death from arrhythmia is the most common cause of death in adults with tetralogy of Fallot, a type of congenital heart disease. It has been shown that dangerous arrhythmias can be induced in almost half of these patients when severe pulmonary valve disease is present. Our study will evaluate the potential for arrhythmias both before and after pulmonary valve surgery, using MRI and electrophysiological testing, to determine if these patients require defibrillators.
