The presence of electrical dyssynchrony (which following an electrocardiogram can be visualised as a left bundle branch block [LBBB]) is an indication for biventricular pacing if it is associated with systolic dysfunction (ejection fraction [EF] <35%) and dyspnoea in New York Heart Association (NYHA) class II–IV. In the great majority of patients, biventricular pacing determines a significant…

Wall motion tracking is an application of pattern-matching ultrasound commonly known as speckle-tracking echocardiography (STE). STE involves creating a template image using a local myocardial region in the starting frame of the image data. In the ensuing frame, an algorithm searches for the local speckle pattern that most closely matches the template. A movement vector is then created using the…

Global and regional left ventricular (LV) function are two of the most common echocardiographic evaluations in daily clinical practice and are essential for the clinical management of patients with various cardiovascular diseases. Global chamber indices such as LV volumes and ejection fraction are used for determining prognosis of patients with ischaemic heart disease, as well as when to plan…

Cardiac resynchronisation therapy (CRT) has achieved widespread approval as a safe and efficient therapeutic strategy for medically refractory congestive heart failure (CHF). The standard indications for CRT include patients with advanced heart failure and evidence of systolic dysfunction (ejection fraction [EF] ≤35%), conduction tissue disease (QRS duration ≥120ms) and marked cardiac symptoms …

The clinical and economic impact of heart failure (HF) is well documented. It affects 22 million people worldwide, occurs in at least 2% of the Western adult population and is a progressive condition with high morbidity and mortality rates, placing a significant burden on healthcare resources.3 One of the keys to reducing the clinical and economic impact of HF is accurate and early diagnosis of…

The introduction of tissue Doppler imaging (TDI) strain was a great achievement in echocardiography and for the first time allowed true quantification of regional myocardial function. The central problem with this technique was the angle dependence and the unfavourable signal-to-noise ratio, which has been partially overcome with 2D speckle tracking. Figures 1 and 2 demonstrate application of…

Heart failure (HF) is a growing and increasingly important chronic disease of the Western world, occurring in at least 2% of the adult population and rising to 3% in those aged over 75 years.1 It is characterised by inadequate systemic perfusion due to impairment of the cardiac pump function. Clinical HF is a progressive condition, typically with high morbidity and mortality rates. It therefore…

Cardiac resynchronisation therapy (CRT) is an established therapy for patients with drug-refractory, highly symptomatic systolic heart failure (HF) and delayed ventricular conduction.1 CRT devices are designed to synchronise the mechanical activity within the left ventricle, between the left and the right ventricle and between the atria and ventricles. Resynchronisation induces reverse…
