Vasa Vasorum The coronary arterial wall generally consists of the tunica intima, tunica media and tunica adventitia. In particular, the coronary adventitia harbours the vasa vasorum (VV),which has a diameter of 50–300 μm and plays an important role as a network of nutrient blood vessels to the arterial wall (Figure 1).1–3 The VV is enhanced in association with arterial wall thickening when the… View more

Coronary Artery Spasm and Adventitial Inflammation Coronary artery spasm plays an important role in the pathogenesis of a wide range of ischaemic heart disease, not only in variant angina, but also in other forms of angina pectoris and myocardial infarction.1,2 Recent studies have demonstrated that coronary spasm is also as frequently noted in European people as in Asian people.3 We have… View more

Despite the recent introduction of vascular closure device (VCD) technology, vascular access site complications remain the leading source of morbidity and costs after the approximately eight to eight-and-a-half million percutaneous catheter-based procedures performed annually worldwide.1 VCD trials consistently demonstrate increased patient satisfaction, early ambulation, and decreased hospital… View more

Atherosclerosis and atherosclerosis-related complications such as coronary, cerebrovascular and peripheral arterial disease show their clinical manifestation in adulthood. However, changes at the endothelial level do not occur suddenly in the elderly, but are the result of a long, on-going, slowly evolving process. We know from autopsy studies that atherosclerotic processes begin in childhood and… View more

Congenital heart disease is the most common congenital malformation and accounts for about eight cases per 1,000 births.1 Due to tremendous developments in cardiac surgery, nearly 90% of all children with congenital heart disease reach adult age. In patients with congenital heart disease, pulmonary arterial hypertension (PAH) may develop due to increased pulmonary arterial flow as a result of a… View more

Digital ischaemia is an uncommon pathology, with an incidence of two cases per 100,000 people per year.1 Diagnosis is mainly based on clinical symptoms: the patient presents a painful digital extremity with signs of ischaemia (blue finger) or even necrosis. Clinical context and medical history are also important to determine the aetiology of digital ischaemia. The role of imaging modalities is… View more

Abstract Several imaging techniques (such as ultrasounds, computed tomography [CT] scan, magnetic resonance imaging [MRI], positron emission tomography [PET] scan, etc.) can provide interesting information on subclinical atherosclerosis and plaque stability. In fact sonographic imaging techniques can be very useful in this field. All of them have their limitations, but each of them has its own… View more

Acute myocardial infarction (AMI) is still a major public health problem worldwide, causing high rates of morbidity and mortality. In the United States, nearly one million patients suffer from AMI each year.1 In the UK, around 80,000 people died from coronary heart disease (CHD) in 2010.2 The current approach to the treatment of myocardial infarction involves early revascularisation with… View more
