More than half of the patients with chronic heart failure (CHF) have associated sleep-disordered breathing (SDB), which consists of either obstructive sleep apnoea (OSA) or central sleep apnoea (CSA).1,2 SDB has deleterious effects on systolic and diastolic ventricular function. In patients with CHF, the presence of SDB results in a poorer prognosis;3,4 thus, its early recognition and adequate… View more

Abstract Mitral regurgitation (MR) is the most commonly found valvular lesion in echocardiography laboratories. Moderate and severe mitral regurgitation have proven to be associated with increased morbidity and mortality, and surgical reconstruction is recommended in severe cases whenever feasible. Three-dimensional echocardiography (3DE) is superior to conventional echocardiography in the… View more

Stress echocardiography is a widely used clinical technique that provides invaluable information in patients with known or suspected coronary artery disease (CAD). Common applications of stress echo include the diagnosis of reversible ischaemia, myocardial viability, and establishing the functional significance of known coronary lesions. Stress echo has been shown to have similar sensitivity and… View more

Mitral valve disease is a common disease that requires an accurate evaluation in order to decide when and how the problem should be treated. Realtime three-dimensional echocardiography (RT3-D) is a new technique that allows us to visualise the mitral valvular anatomy in any desired space orientation. This review will focus on two specific subject areas in which our research team has been working:… View more

There has been a considerable evolution in technology since the initial description of 3D echocardiography several decades ago.1 The first generation of 3D probes performed gated acquisition with static rendering of images, but not in realtime. The second generation did to an extent allow realtime imaging, but the relatively low density of active elements (approximately 300) resulted in a low… View more

Cardiovascular imaging is a rapidly growing area, where technological development combined with clinicians’ demand for optimal visualisation of the heart might lead us to a situation where costs are high and evidence is sparse. Applying the correct imaging modality is thus an important task in clinical practice. The aim of this article is to discuss the present and future potential of deformation… View more

Coronary artery disease (CAD) represents a tremendous financial and health burden as the leading cause of death in the US.1 Acute coronary syndrome and its subsequent manifestations, including heart failure and need for cardiac transplantation, are associated with significant morbidity and mortality. Hypertension, dyslipidemia, tobacco abuse, diabetes, chronic kidney disease, and family history… View more

Myocardial revascularisation can improve or relieve angina pectoris in symptomatic patients and also improve prognosis in patients with severe left main stem disease, severe proximal left anterior descending (LAD) coronary disease or multi-vessel coronary artery disease (CAD).1–2 However, it is also widely accepted that the visual estimation of stenosis severity at the time of cardiac… View more

How Far Have We Come? Cardiac imaging using ultrasound (so-called ‘echocardiography’) was introduced more than 50 years ago. Resting echocardiographic detection of myocardial infarction was described as the reduction in regional contractile function,1 and the development of stress echocardiography in the early era was recognised after the introduction of 2D echocardiographic imaging. The initial… View more
