A 22-year-old woman with cystic fibrosis developed QTc interval prolongation following lung transplantation in the setting of voriconazole therapy. After the discontinuation of voriconazole and initiation of isavuconazole, her QTc interval normalized. This case highlights the unique property of QTc interval shortening by isavuconazole among the triazole antifungals.
