Computed tomography (CT) of the heart combines X-ray images with the aid of a computer to generate cross-sectional views of the body. Cardiac CT uses advanced CT technology with or without intravenous contrast dye to visualise cardiac anatomy, coronary circulation, and the great vessels. Cardiac CT is especially useful in evaluating the myocardium, coronary arteries, pulmonary veins, thoracic… View more

Sources of Radiation Exposure Radiation used in medical examinations and tests is the largest man-made source of radiation exposure. The biological effects of the radiation dose received is expressed in milliSievert (mSv), with the effective dose of 1 mSv corresponding to the radiation dose of 50 chest X-rays. An average of 2.4 mSv per head per year comes from natural sources (see Figure 1).1… View more

The field of heart transplantation has evolved tremendously since Alexis Carrel first explanted a canine heart and anastomosed it to the carotid artery and jugular vein of a recipient dog in 1905.1 In 1960, Norman Shumway and Richard Lower at Stanford described a technique for orthotopic canine heart transplantation and demonstrated adequate physiologic function of the denervated heart.2 Their… View more

Amyloidosis is a condition characterised by accumulation of pathologic fibrillar proteins in organs causing dysfunction.1 Several protein precursors have been shown to cause amyloidosis.2 Cardiac amyloidosis, when waxy, starch-like deposits infiltrate the heart, is most commonly secondary to the accumulation of amyloid fibrils derived from immunoglobulin light chains (AL) or transthyretin (ATTR)… View more

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… View more

Coronary heart disease (CHD) is the leading cause of death in most countries. It is also a major cause of physical disability, particularly in the rapidly growing population of elderly people. The prevention of subsequent coronary events and the maintenance of physical functioning in such patients are major challenges in preventative care. Cardiac rehabilitation (CR) programmes were first… View more

The evidence supporting the beneficial effects of physical activity on health is compelling. Regular exercise reduces cardiovascular mortality by 35 % and all-cause mortality by 33 %1 and confers an average of 7 years greater longevity.2 Most professional athletes, however, undertake doses of exercise that far exceed those recommended by the current evidence, which has been adopted by national… View more
