Abstract:
Torsades de pointes is a kind of life-threatening ventricular tachyarrhythmia. We report a case of torsades de pointes in an 8-year-old boy with acute rejection after orthotopic heart transplantation. The causes of torsades de pointes could be either congenital or acquired. In this case, various causes including acute rejection-related repolarisation heterogeneity, dose-dependent acquired long QT resulting from treatment with immunosuppressants, and AKAP9 (A-kinase anchoring protein 9) genetic variants are the possible mechanisms.
