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…

Despite the fact that more than 20 years have passed since the clinical introduction of cardiac resynchronisation therapy (CRT), one of the key questions – do we need an ICD for primary prevention of sudden cardiac death (SCD) in CRT patients? – is still unanswered.
Prospective Randomised Controlled Trials
Multiple prospective randomised controlled trials have been conducted to establish the…

Since the introduction of CRT more than 20 years ago, its role in mild to severe systolic heart failure has become well established. CRT has been shown to decrease mortality, reduce heart failure hospitalisations and improve functional status in patients with NYHA class II–IV heart failure and QRS prolongation, most commonly with LBBB pattern.1 One of the major limitations of CRT implementation…

Sustained ventricular tachycardia (VT) and ventricular fibrillation (VF) are typically a manifestation of significant structural heart disease and often associated with a high risk of sudden cardiac death. Implantable cardioverter defibrillators (ICDs) remain the mainstay of therapy for prevention of sudden cardiac death associated with these arrhythmias.1 However, ICDs treat the arrhythmia after…

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…

Pioneering electrophysiology studies in the 1990s defined the anatomical boundaries of typical atrial flutter, identified regions for effective catheter ablation of this arrhythmia and described procedural endpoints to minimise recurrences after ablation. Activation and entrainment mapping demonstrated that typical flutter arises from reentry around the tricuspid annulus.1 Criteria to confirm…

Scar-related reentrant ventricular tachycardia (VT) may be present in a variety of structural heart disease (SHD) phenotypes. In this setting, VT circuits are comprised of viable myocytes separated by fibrosis, allowing for the slow conduction needed to facilitate reentry.1,2 Aetiologies of fibrosis include ischaemic heart disease (IHD), inflammatory conditions, infiltrative cardiomyopathy,…
