[Radiofrequency ablation of recurrent monomorphic ventricular tachycardia in a patient with severe systemic...

A case of progressive systemic scleroderma in a 33 year-old woman who was referred to our Arrhythmia Unit due to daily palpitations and dizziness is presented. The 24-hour Holter recording showed monomorphic ventricular tachycardia which lasted several minutes. Hemodynamic study showed dilated right chambers and right ventricular dysfunction, without pulmonary hypertension. Left ventricular angiography and coronary arteries were normal. During programmed electrical stimulation, two different ventricular tachycardia were induced and ablated with radiofrequency on the right ventricle. The patient remains free of recurrence of tachycardia after (10 months of follow up). Patients with progressive systemic scleroderma may present several different cardiac arrhythmias. Involvement of the right ventricle is particularly frequent as is the origin of ventricular tachycardia in this ventricle. Radiofrequency catheter ablation is safe and effective in the management of these patients.
