Introduction
In the UK there is still an emphasis on coronary anatomy as currently assessed using coronary angiography; however, high-grade coronary lesion may not cause myocardial ischaemia, for example in the presence of extensive collateral vessels. Dynamic imaging to show the physiological effect of any coronary stenosis is therefore an important part of the investigation of patients with…

Stress echocardiography, which was introduced in the early 1980s, has matured to a reliable cost-effective method for diagnosing and risk-stratifying patients with suspected or known coronary artery disease (CAD). The use of stress echocardiography as the non-invasive method of choice for assessment of CAD has increased exponentially worldwide. In the US alone, approximately three million stress…

Takotsubo cardiomyopathy (TC) or syndrome was first described more than 2 decades ago by Dote and colleagues in Japan, but has since been increasingly recognised around the world.1 Takotsubo is the Japanese name for a the traditional octopus trapping pot that has a round bottom and narrow neck, resembling the appearance the left ventricle during the acute presentation (see Figure 1).2 Although,…

Takotsubo syndrome is an acute reversible heart failure syndrome, which is increasingly recognised by coronary angiography for patients with acute ‘cardiac’ chest pain.1 It is a distinct disease entity from acute coronary syndrome, although the initial presentation has similar features to either ST elevation myocardial infarction (STEMI) or non-ST elevation myocardial infarction (NSTEMI). Early…

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…

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…

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…
