Radiofrequency catheter ablation of recurrent monomorphic ventricular tachycardia in a patient with severe systemic scleroderma

A case of progressive systemic scleroderma in a 33 year-old woman who was r eferred to our Arrhythmia Unit due to daily palpitations and dizziness is p resented. The 24-hour Holter recording showed monomorphic ventricular tachy cardia 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 pr ogrammed electrical stimulation, two different ventricular tachycardia were induced and ablated with radiofrequency on the right ventricle. The patien t remains free of recurrence of tachycardia after (10 months of follow up). Patients with progressive systemic scleroderma may present several differe nt cardiac arrhythmias. involvement of the right ventricle is particularly frequent as is the origin of ventricular tachycardia in this ventricle. Rad iofrequency catheter ablation is safe and effective in the management of th ese patients.
