| Popis: | Objective: To assess the effect of pulmonary valve replacement (PVR) on the repolarization of patients with tetralogy of Fallot. Background: Pulmonary valve regurgitation may cause right ventricular failure in adult patients with Fallot's tetralogy. In these patients, prolonged depolarization and disturbed repolarization are associated with ventricular arrhythmias and sudden cardiac death. Methods: Thirty Fallot patients (age 32 9 years, 19 male) eligible for PVR were studied with cardiac magnetic resonance imaging (CMR) before and 6 months after PVR. Electrocardiograms obtained during initial and follow-up CMR were analyzed and occurrence of ventricular arrhythmias was studied. Results: Right ventricular end-diastolic volume (RV EDV) decreased from 322 87 to 215 +/- 57 ml after PVR (P 160 ms. No severe ventricular arrhythmias were found in patients with a RV EDV |
