This report describes the clinical course of a patient with left ventricular assist device (LVAD) and refractory ventricular tachycardia (VT) who underwent successful left ventricular (LV) mapping and ablation complicated by the presence of a bioprosthetic aortic and a mechanical mitral valve. LV catheterization was achieved by crossing the mechanical valve. The patient remained hemodynamically stable during the procedure most likely as a result of LVAD support. There were no complications. A recurrence of monomorphic VT 2 months later required a second VT ablation procedure using the same transseptal‐transmitral approach. The patient has since been free of implantable cardioverter defibrillator shocks for 2 months since the second procedure. (PACE 2010; 900–903)
