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…

Heart failure (HF) is a growing and major health burden in western countries. The prevalence of HF is estimated at 1–2 % in the western world, and the incidence approaches 5–10 per 1,000 persons per year.1Cardiac resynchronisation therapy (CRT) has been shown in multiplestudies to improve HF symptoms, quality of life and improve survivals.2–6The two landmark studies, Comparison of Medical Therapy…

Mechanical dyssynchrony, ie nonsynchronous contraction of the wall segments of the left ventricle (intraventricular) or between the left and right ventricles (interventricular), impairs systolic function and ventricular filling, increases wall stress and worsens mitral regurgitation. It is most readily defined by the presence of QRS widening and left bundle branch block (LBBB) configuration on…

Approximately 2 % of the adult population in high-income countries has clinical heart failure (HF),1 and almost the same percentage again has impaired left ventricular (LV) function without symptoms.2 The incidence and prevalence of HF rises steeply with age; the mean age at first diagnosis being 76 years,3 with about half of these patients having a left ventricular ejection fraction (LVEF) of …

CRT is an essential treatment for patients with heart failure and reduced ejection fraction as it can restore left ventricular (LV) electrical and mechanical synchrony. It has been shown to increase quality of life, improve functional status, reduce hospitalisation, improve LV systolic function and reduce mortality in properly selected patients.1,2 While CRT is an effective therapy, approximately…

Prevalence of Functional Mitral Regurgitation in Patients with Chronic Heart Failure
Secondary or functional mitral regurgitation (FMR) is a common problem in patients with chronic heart failure (HF) due to dilated cardiomyopathy, regardless of aetiology.1 FMR results from an imbalance between the closing and the tethering forces that act on the mitral valve leaflets.2,3

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…
