Sudden cardiac death due to ventricular arrhythmias remains the most common cause of death in developed nations. Implantable cardioverter defibrillators have been shown to improve mortality in high-risk groups for ventricular tachyarrhythmias, but they are not curative, with the risk of arrhythmia recurrence remaining unaltered. ⋯ Recent advances in catheter ablation for VT have increased the efficacy in creating adequate lesions, accurate three-dimensional maps and mapping haemodynamically unstable VT, all of which have increased the utility of this modality in the treatment of ventricular arrhythmias. In this article, we review the recent advances that have fuelled renewed interest in catheter ablation of VT, its clinical utility and who should be referred.

Case ReportsReversible posterior leukoencephalopathy syndrome: diagnosis and management in the setting of lung transplantation.
Reversible posterior leukoencephalopathy syndrome (RPLS) is a potentially devastating early complication of calcineurin inhibitor (CNI) therapy in solid organ transplantation. Management centres on cessation of CNI therapy; however, this strategy is complicated in lung transplantation because of the threat of allograft rejection, or, if CNI is replaced with mammalian target of rapamycin-based immunosuppression, poor wound healing and bronchial dehiscence. We describe four cases of RPLS after lung transplantation, emphasizing the diagnostic and management approach required to maintain a healthy allograft and ensure that RPLS is, as the name suggests, reversible.
