Ablación por radiofrecuencia de extrasistolía ventricular aislada sintomática en corazón sano

Introduction: Premature ventricular depolarizations (PVDs) in patients without heart disease, are a frequent clinical problem that can cause important symptoms. Most commonly, this benign arrhythmia responds to treatment with antiarrhythmic drugs. However, occasionally PVDs are refractory to pharmac...

Most commonly, this benign arrhythmia responds to treatment with antiarrhythmic drugs. However, occasionally PVDs are refractory to pharmacological treatment but they can be eliminated with radiofrecuency catheter ablation. Aim: To show our experience with four patients in whom we used this method. Material and method: We studied three men and a woman, twelve to forty six years old. All of them were symptomatic, their EKG and echocardiogram were normal and they had been treated with several drugs without response. In three of them the PVDs had left bundle-branch block morphology with inferior axis; the other patient had right bundle-branch block morphology with superior axis. The origin of the PVDs was determined using pace mapping. Results: Two of the patients had spontaneous PVDs; in the other two isoproterenol infusion was used to induce them. In three patients the origin of the PVDs was located in right ventricular outflow and in the other in the anterolateral region of the left ventricle. None had sustained atrial or ventricular arrhythmia. In all of them PVDs were eliminated. A patient presented a second morphology that could not be treated. None of the patients had complications and they were discharged within the next 24 hours. Three noted symptomatic improvement and after 18 months, only one had a probable recurrence of the arrhythmia. Conclusions: radiofrecuency catheter ablation can be successfully used to eliminate PVDs in severely symptomatic and drug-resistant patients (Rev Méd Chile 2001; 129: 60-66)info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.129 n.1 20012001-01-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872001000100008es10.4067/S0034-98872001000100008
