Abstract:
Isolated noncompaction of left ventricular myocardium (IVNC) is categorized as an unclassified cardiomyopathy by the World Health Organization. We describe the case of a 29-year-old woman who was diagnosed with IVNC after suffering two syncopes caused by an atrioventricular nodal reentrant tachycardia (AVNRT) that was successfully ablated. We report successful radiofrequency ablation in an adult with this cardiomyopathy. Although the presence of syncope in these patients obliged us to rule out a ventricular tachycardia as the most probable etiology, our case shows how an exhaustive study is needed to look for other possible and curable causes.
