Chronic Left Coronary Artery Stenosis After Radiofrequency Ablation of Idiopathic Premature Ventricular Contraction Originating From Left Coronary Sinus Cusp.
A 50-year-old man was referred for radiofrequency catheter ablation of idiopathic premature ventricular contraction (PVC) refractory to metoprolol. The ECG characteristics of the PVCs suggested that the PVCs originated from left coronary sinus (LCC). Mapping was performed in the LCC using a 7F irrigated-tip ablation catheter via the right femoral artery. During clinical PVCs, the local ventricu...
متن کاملWorsening of mitral valve regurgitation after radiofrequency catheter ablation of ventricular arrhythmia originating from a left ventricular papillary muscle
Introduction Papillary muscles (PMs) of the left ventricle (LV) have been shown to be a potential origin of ventricular arrhythmias (VAs) in patients with or without structural heart disease. Recently, a “malignant” arrhythmia phenotype in patients with mitral valve prolapse (MVP) who experienced lifethreatening VAs has been reported. This subset of patients with MVP was characterized by comple...
متن کاملIdiopathic ventricular premature contractions originating from the postero-lateral tricuspid annulus leading to left ventricular disfunction.
A 19-year-old patient with premature ventricular complexes (PVCs) more than 30% on 24 hours was addressed for catheter ablation. Echocardiography showed left ventricular (LV) dilation and systolic dysfunction with 37% of ejection fraction. The patient underwent investigations including cardiac magnetic resonance (MRI) with no other cause of cardiomyopathy being found. Successful ablation of the...
متن کاملThe Significance of Repetitive Ventricular Responses Induced by Radiofrequency Energy Application for Idiopathic Left Ventricular Tachycardia
In radiofrequency (RF) ablation for idiopathic left ventricular tachycardia (ILVT), the termination of tachycardia during RF ablation is considered a hallmark of success. However, in cases of patients with difficulty of induction of ventricular tachycardia (VT), the evaluation of procedural success can be problematic. We have observed thermal responses reflected as ventricular rhythm change to ...
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...
