Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrial fibrillation (AF), atrial flutter (AFL), and atrial tachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF).

BACKGROUND:Epicardial approach in ventricular tachycardia (VT) ablation is still regarded as a second-step strategy, due to the risk of complications. The epicardial approach was considered useful if epicardial ablation was performed after epicardial mapping. Circulation: Arrhythmia and Electrophysiology, Ahead of Print.

Epicardial catheter ablation of ventricular tachycardia (VT) is a well-established ablation technique for a variety of myocardial substrates including ischemic cardiomyopathy. Epicardial VT ablation has several potential life-threatening complications including a 1.5% incidence of coronary artery (CA) injury.

Belhassen’s ventricular tachycardia is an uncommon arrhythmia in infants. Originating near the left posterior fascicle, it is initiated by supraventricular ectopy or sinus tachycardia and is uniquely sensitive to verapamil. Use of verapamil in infants is controversial due to risk of severe hemodynamic compromise.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disease characterised by fibrofatty replacement of the ventricular myocardium due to specific mutations, leading to ventricular arrhythmias and sudden cardiac death. Additionally, the impact of sotalol and amiodarone is inconsistent with studies reporting contradictory results.
