Chagas disease is an important public health problem in Latin America. Almost 25% of the population (approximately 65 million individuals) are at risk of infection and another 6 million people are affected.1 However, migration and globalisation have resulted in the increased presence of Chagas disease worldwide, particularly in the US and Europe.
Chagas disease is caused by a parasite, the…

Ventricular tachycardia (VT) is one of the most challenging medical conditions faced by cardiac patients and physicians treating them. Antiarrhythmic medications have limited effectiveness and are frequently poorly tolerated.1–4 Catheter ablation is increasingly used to treat patients successfully.1,5–7 Most VTs can be ablated endocardially but some require epicardial mapping and ablation…

Atrial fibrillation (AF) is the most common clinical arrhythmia with a relevant socio-economic impact.1–3 Patients with atrial fibrillation are characterised by symptoms such as palpitations and shortness of breath; they have reduced exercise capacity and are subject to a higher risk of thromboembolic events. In spite of a relatively simple diagnosis, management of AF patients is difficult for…

Arrhythmogenic cardiomyopathy (ACM) is usually referred to as arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D).1A first historical description was made in 1736, whereas its first modern description dates back to 1982.2 Initially, ACM was thought to be an embryological malformation.3 Yet in recent years it became evident that the pathophysiology of an ongoing genetically…

Recurrent episodes of ventricular tachycardia (VT) in patients with structural heart disease are associated with increased mortality and morbidity, despite the life-saving benefits of implantable cardiac defibrillators (ICDs).1,2 Because ICD therapies are abortive and do not alter the underlying arrhythmogenic substrate, their reduction becomes important, especially as recurrent shocks can cause…

Catheter-based ablation has been a well-established tool in the treatment of ventricular tachycardia (VT). However, the effectiveness of catheter ablation may be limited by its ability to access sites of arrhythmogenic tissue and achieve adequate lesion size in target areas without risking collateral damage. Antiarrhythmic surgery would be an effective alternative in such situations. Despite the…

Ventricular tachyarrhythmias (VAs) most commonly occur early in ischaemia, and patients presenting with an acute MI and ventricular arrhythmias are a group that has a significantly increased risk of mortality.1,2 Thrombolysis primary percutaneous coronary intervention (PCI) and use of beta-blockers, while resulting in the modification of the natural history of an infarct, have also reduced the…

Device therapy is increasingly employed in the management of complex congenital heart disease (CHD). Bradycardias, most often related to sinus nodal dysfunction (SND) or atrioventricular nodal (AVN) block, may necessitate the implantation of pacing devices, while malignant arrhythmias may be treated by appropriate use of implantable cardioverter defibrillators (ICDs). However, there is a complex…
