Successful recovery of tachycardia-induced cardiomyopathy with severely depressed left ventricular systolic function by catheter ablation with mechanical hemodynamic support: a case report

Kazuhiro Kamada et al. Clin Case Rep. .

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.

Keywords: Cardiogenic shock; clinical: catheter ablation – atrial fibrillation; intra‐aortic balloon pump; mechanical hemodynamic support; tachycardia‐induced cardiomyopathy.

Figure 1
(A) Transthoracic echocardiography on admission showed a dilated left atrium and left ventricle. The left ventricular wall motion was severely and diffusely hypokinetic. The left ventricular ejection fraction calculated by the biplane Simpson's method was 15%. (B) Transthoracic echocardiography after 6 months depicted systolic function improvement in both the left atrium and left ventricle. The left ventricular ejection fraction was 50%.

Cardiac computed tomography before (top) and 12 months after (bottom) catheter ablation. The left atrial size dramatically decreased after treatment.
