[The first case of radiofrequent ablation of ventricular tachycardia in a patient with ischemic cardiomyopathy in our country].

Ablation of ventricular tachycardia in patients with ischemic cardiomyopathy is more complicated and more difficult than ablation of most supraventricular tachycardias. Arrhythmogenic substrate is complex and its localisation is often unclear. Because of the tachycardia characteristics, more precise mapping methods often can't be utilised. Also, patients are usually seriously ill with decreased systolic function, heart failure, ischemia and various comorbidities where tachycardia induction and ablation procedure may facilitate abrupt hemodynamic disturbance. Uninducibility of the clinical tachycardia can be achieved in 65-95% of patients, but tachycardia recurs in 20-44% of patients. Serious complications were noted in 8% of patients with lethal outcome in 2.7% of patients. Decision about therapeutic strategy should be made individually according to potential risk and procedure benefit. This paper presents the first case of the successful ablation of ventricular tachycardia in a patient with ischemic cardiomyopathy in our country.
