Left ventricular dysfunction resulting from frequent unifocal ventricular ectopics with resolution following radiofrequency ablation.
A case is presented, in which asymptomatic but persistent right ventricular outflow tract (RVOT) ectopics resulted in left ventricular (LV) dilatation and systolic dysfunction. The patient underwent extensive investigation with no other cause for the cardiomyopathy being found. Successful ablation of the RVOT ectopic focus resulted in normalization of LV size and function. This case suggests th...
متن کاملRadiofrequency Catheter Ablation of Ventricular Premature Complexes
Frequent ventricular premature complexes (VPC) can result in left ventricular dysfunction. Several case reports have found this association and reversal with radiofrequency ablation [1-4]. Other peculiar problems reported to be due to VPCs and relieved by radiofrequency ablation include intermittent claudication [5], chronic cough with cough syncope [6,7] and dysphagia [8], mostly by the same g...
متن کاملRadiofrequency catheter ablation for ventricular tachycardia.
Radiofrequency energy was used for the ablation of chronic recurrent ventricular tachycardia (VT) in 58 patients who were divided into two groups: 44 cases with structural myocardial disease (36 men and 8 women: mean age 55 years; range: 14 to 85 years) with an average left ventricular ejection fraction of 38% (range: 15 to 80%): these patients had myocardial infarction (28 cases), arrhythmogen...
متن کاملRadiofrequency Ablation for Post Infarction Ventricular Tachycardia
Radiofrequency ablation has an important role in the management of post infarction ventricular tachycardia. The mapping and ablation of ventricular tachycardia (VT) is complex and technically challenging. In the era of implantable cardioverter defibrillators, the role of radiofrequency ablation is most commonly reserved as an adjunctive treatment for patients with frequent, symptomatic episodes...
متن کاملRadiofrequency catheter ablation of ventricular tachycardia after myocardial infarction.
BACKGROUND Patients with ventricular tachycardia (VT) after myocardial infarction often have multiple morphologies of inducible VT, which complicates mapping and is viewed by some as a relative contraindication to ablation. Attempting to identify and target a single "clinical" VT is often limited by inability to obtain 12-lead ECGs of VTs that are terminated emergently or by defibrillators. Thi...
