Over the last 20 years ventricular tachycardia (VT) ablation has evolved from a treatment modality for selected patients withrecurrent haemodynamically tolerated VT (which can be mapped during ongoing arrhythmia), to a therapeutic option for patients with tolerated and untolerated VT using substrate-based ablation strategies.1 The substrate for VT after myocardial infarction (MI) consists of… View more

The increasing use of cardiac implantable electronic devices (CIEDs) for management of cardiac conditions has over the last few years been associated with higher infection rates.1 Expanded CIED use alone cannot account for this rise,2–4 which involves both patient- and device-related factors. Indeed patients are tending to be older and presenting with co-morbidities, while devices are becoming… View more

Management of Cardiac Sarcoidosis in 2020
Author(s): Nisha Gilotra , David Okada , Apurva Sharma , et al Added: 3 years ago
Sarcoidosis is an inflammatory granulomatous disease that can affect any organ. Systemic sarcoidosis is known to affect young adults, with a second peak in women >50 years of age, as demonstrated in Scandinavian and Japanese studies.1–4 In the US, the lifetime risk of sarcoidosis is 2.4% for black people and 0.85% for white people.1 The incidence of cardiac involvement has been increasingly… View more

Multimodality Imaging to Guide Ventricular Tachycardia Ablation in Patients with Non-ischaemic Cardiomyopathy
Author(s): Ling Kuo , Jackson J Liang , Saman Nazarian , et al Added: 3 years ago
Catheter ablation has been increasingly used as a treatment for refractory ventricular tachycardia (VT) in patients with non-ischaemic cardiomyopathy (NICM). However, ablation outcomes tend to be quite variable because of the heterogeneity of the aetiology for the NICM and associated VT substrate in these patients.1–3 Patients with NICM can be sub-classified based on specific genotypic and… View more

Ventricular arrhythmias (VA) are commonly associated with structural heart disease and have substantial impact on patient outcomes and health system costs. Within the realm of cardiomyopathy (CM), there has been substantial progress with respect to ischaemic CM (ICM) in the understanding of infarct related scar biology and scar-mediated ventricular tachycardia (VT). This has led to interventions… View more

Cardiac implantable electronic device (CIED) therapy is effective and safe. However, infections related to CIED treatment may have devastating consequences, causing significant morbidity, mortality and generating considerable healthcare costs.1–6 Temporal trends in CIED treatment indicate a disproportional increase in CIED infections relative to implantation rates.1,7,8 Reasons for this trend are… View more

The use of cardiovascular implantable electronic devices (CIEDs) has increased dramatically, with approximately 1.2–­1.4 million CIEDs implanted annually worldwide.1 In the US alone, there are more patients with CIEDs than registered nurses.2,3 CIEDs use leads that connect a generator to cardiac tissue to treat patients with many conditions including symptomatic bradycardia, morbid tachycardia… View more

The structural and/or functional abnormality of the cardiac electrovascular system is the most common cause of world mortality accounting for 29.0 % of deaths, followed by infectious diseases (16.2 %) and cancers (12.6 %) (WHO 2008 report). 1 Abnormalities in the cardiac electrical system (arrhythmias and sudden death) and/or mechanical function (heart failure) constitute one of the major causes… View more

Cardiac resynchronisation therapy (CRT) is a widely-performed standard treatment for improving cardiac function and quality of life in patients with heart failure.1 After CRT, however, 30–40 % of patients do not experience improvements in left ventricular (LV) function and clinical symptoms.2–3 The key factors for increasing the response rate to CRT are identification of the optimal LV lead… View more
