Ablation of idiopathic ventricular arrhythmias from the right ventricular apex

Heart Rhythm
Idiopathic ventricular arrhythmias (VAs) from the right ventricle (RV) are well-described, but limited data exist regarding those from the RV apex.The purpose of this study was to define the electrocardiographic (ECG) characteristics and ablation outcomes of RV apical VAs, including premature ventricular contractions (PVCs) and ventricular tachycardia ...

Idiopathic Ventricular Arrhythmias Originating From the Left Ventricular Summit [PDF]

Circulation: Arrhythmia and Electrophysiology, 2010
Background— The summit of the left ventricle (LV) is the most superior portion of the epicardial LV bounded by an arc from the left anterior descending coronary artery, superior to the first septal perforating branch to the left circumflex coronary artery.

Catheter ablation of ventricular tachycardia via the coronary veins

Indian Pacing and Electrophysiology Journal
Ventricular arrhythmias, either idiopathic or those associated with organic heart diseases, may originate from the epicardial side of the ventricular myocardium. Therefore, mapping and ablation via the coronary venous system offers a convenient, feasible,

Clinical Outcomes After Catheter Ablation in Patients With Structural Heart Disease and Ventricular Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction In patients with ischemic cardiomyopathy (ICM), recurrent VF may be treated with catheter ablation by targeting triggering premature ventricular complexes (PVCs) and/or ventricular scar homogenization. Data on optimal ablation strategies in patients with non‐ischemic cardiomyopathy (NICM) remain limited.

A Stepwise ECG Algorithm to Resolve Identical Precordial Transition in Idiopathic Outflow Tract Ventricular Arrhythmias

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Accurate pre‐procedural differentiation of right (RVOT) versus left ventricular outflow tract (LVOT) origin in idiopathic outflow tract ventricular arrhythmias may facilitate procedural planning and mapping strategy. However, existing 12‐lead ECG criteria show variable performance and often fail to provide clear discrimination when ...

Doxorubicin‐induced Cardiotoxicity in Dogs: A Narrative Review

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Doxorubicin, an anthracycline widely used in both human and veterinary oncology, is highly effective against a variety of malignancies in dogs, including lymphomas, sarcomas and carcinomas. Despite its efficacy, doxorubicin exposure can be associated with cardiotoxicity, which may present acutely or chronically, potentially leading to severe ...

Senolytics and exercise: Dual modalities for rejuvenating muscle

The Journal of Physiology, EarlyView.
Abstract figure legend The role of senolytics on the heart and skeletal muscle. Senescent cell burden increases with ageing, disuse and disease. The senolytics dasatinib+quercetin (D+Q), navitoclax and fisetin, as well as exercise, eliminate senescent cells, reducing senescent cell burden and their senescence‐associated secretory phenotype (SASP ...
