title: Successful recovery of tachycardia-induced cardiomyopathy with severely depressed left ventricular systolic function by catheter ablation with mechanical hemodynamic support: a case report.
abstract: We describe the case that persistent atrial fibrillation refractory to rhythm control by pharmacotherapy and electrical cardioversions caused tachycardia-induced cardiomyopathy with low ejection fraction and hemodynamic instability. Mechanical hemodynamic support using an intra-aortic balloon pump is one of the choices of hemodynamic support during catheter ablation by pulmonary vein isolation.
