Introduction
The heart is a dynamic organ and places special demands on three-dimensional (3-D) techniques. To understand its physiology and pathophysiology, not only the spatial distribution of its structures is important but also their movement during the cardiac cycles. Previous approaches to 3-D echocardiography (3-DE) were offline and based on sequential rotational scanning and acquisition…

Background
Echocardiography has evolved into the most predominant diagnostic imaging technique in cardiology. Over the last five decades the diagnostic capability of echocardiography has increased dramatically from M-mode to two-dimensional (2-D) imaging. Recent advances in ultrasound instrumentation and computer technology have led to three-dimensional (3-D) echocardiography, introducing a new…

The field of non-coronary cardiac intervention is undergoing rapid expansion, driven by advances in technology and increasing demand for alternative, non-surgical therapies for common structural heart diseases. As a result, the volume, variety and complexity of percutaneous catheter-based procedures being performed in cardiac catheterisation laboratories are increasing. Traditionally, fluoroscopy…

Coronary flow velocity reserve (CFVR) represents the ratio between maximal (stimulated) coronary blood flow, induced by using a coronary vasodilator, and baseline (resting) blood flow (see Figure 1). As a ratio it is a dimensionless variable. It could be measured with different tools – some of them, such as intracoronary Doppler flow wire and coronary sinus thermodilution, are invasive methods…

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…

Echocardiography is the most widely used non-invasive imaging method in cardiology worldwide. Several reasons justify its success, the most important being its ability to answer easily and repeatedly the pertinent clinical questions posed every day by clinicians about their patients. In addition, it has accommodated itself to the continuous technological and scientific developments of the last…

Non-invasive imaging of the heart continues to evolve and improve. Cardiovascular ultrasound (echocardiography) continues to play an important role in the diagnosis and assessment of responses to therapy of many cardiac conditions. Even as the clinical applications of newer techniques such as cardiac computed tomography (CT) and cardiac magnetic resonance imaging (CMRI) increase, the role of…

Coronary artery disease (CAD) remains a diagnostic challenge, even though there are several diagnostic techniques available for the detection of ischaemia – assessed either as function or perfusion abnormalities or directly by demonstrating anatomical coronary stenoses.1 An overview of different non-invasive modalities used in the diagnosis of myocardial ischaemia and their average sensitivity…
