Idiopathic Ventricular Fibrillation: Look for the Hidden Guilty—A case of aborted cardiac death.

We report a unique case of a 6-year-old male child with aborted sudden cardiac death due to ventricular fibrillation. A rare anomalous aortic origin of the right coronary artery was detected and supposed to be the cause of the malignant arrhythmia. Clinical exome sequencing did not reveal any pathogenic variant related to channelopathies nor other known heart-related genes. The patient underwent cardiac surgery and a cardiac defibrillator was implanted for secondary prevention. [ABSTRACT FROM AUTHOR]
