Catheter ablation of premature ventricular contractions originating from the His bundle region.

چکیده
We describe a 35-year-old man with idiopathic frequent premature ventricular contractions (PVCs) originating from the His-bundle region, where a low frequency ventricular potential was recorded in the bipolar recording and QR pattern in the unipolar recording. Electro-anatomical mapping revealed a confined low voltage zone (<1.2 mV) in the His-bundle region, and the activation spread out radially to the entire right ventricle. The PVCs were successfully abolished without any atrioventricular block by a step-wise incremental radiofrequency energy application to the His-bundle region. The patient has remained free from PVCs or any symptoms without medication during a 23 month follow-up period.

It has been demonstrated that catheter ablation may be a reliable technique for curing ventricular arrhythmias originating from the great cardiac vein (GCV), and there are some challenges and risks with this therapeutic method. Although some reports described successful catheter ablation of ventricular tachycardias originating from the GCV, premature ventricular contractions (PVCs) with left bu...

BACKGROUND Premature ventricular contractions (PVCs) originating from aortic sinus cusps is not infrequent and can be eliminated effectively by radiofrequency ablation with rare complications. However, after a review of the medical literature, and to our knowledge, this is the first case of successful idiopathic aortic sinus cusps-PVC-ablation using a 3-dimensional (3D) mapping system in an adu...

Two cases of frequent ventricular ectopy are described. Case one: a 49 year-old woman with post myocarditis extrasytoles (34 000/24 h). The ectopic focus was located on the tricuspid annulus - directly in the area of largest and sharpest His bundle potential and where direct His bundle capture was observed during all pace mapping attempts. Case two: a 15 year- -old men with idiopathic, very fre...
متن کاملCatheter Ablation of Idiopathic Premature Ventricular Contractions and Ventricular Tachycardias Originating from Right Ventricular Septum
BACKGROUND Idiopathic premature ventricular contractions (PVCs) and ventricular tachycardias (IVTs) originating from the subtricuspid septum and near the His bundle have been reported. However, little is known about the prevalence, distribution, electrocardiographic characteristics and the efficacy of radiofrequency catheter ablation (RFCA) for the ventricular arrhythmias arising from the right...

A 59-year-old female with frequent, drug-refractory ventricular premature beats (VPBs) was referred for catheter ablation. On her resting ECG, monomorphic VPBs were present in bigeminic pattern with axis similar to sinus rhythm, transition zone in lead V3 and slurring in leads III, V2, and V3 (Figure 1A). During the procedure, the earliest ventricular activation site was localized just below th...
