Abstract

Aim: to evaluate the effect of extracorporeal membrane oxygenation (ECMO) as a life support in the treatment of a patient with refractory ventricular tachycardia developed after Fontan procedure.

Patient and treatment. A 4-year-old child developed refractory ventricular tachycardia (up to 250 bpm) and hemodynamic depression 18 hours after the Fontan procedure. After the failure of cardiopulmonary resuscitation and antiarrhythmic therapy, resternotomy with central venoarterial (VA) ECMO support was performed, followed by diagnostic angiocardiography. Contrast-enhanced cavopulmonary angiography revealed stenosis of the left pulmonary artery, which was treated with balloon angioplasty and stenting.

Results. Ventricular tachycardia resolved and sinus rhythm was restored within 24 hours after left pulmonary artery stenting, supported by continuous ECMO and antiarrhythmic therapy. On day 3, transthoracic echocardiography showed good single ventricle contractility after a trial weaning from ECMO. As a result, the ECMO support was removed and the sternum sutured. The patient was discharged from the hospital on day 47 in stable condition.

Conclusion. The prompt initiation of VA ECMO support in a 4-year old patient with refractory ventricular tachycardia post-Fontan procedure along with the complex management of post-procedural residual tachycardia using a combination of antiarrhythmic agents helped restoring sinus rhythm and could contribute to preventing neurological complications.
