BACKGROUND: Various techniques have been employed for the early detection of perioperative cerebral ischaemia and hypoxia. Cerebral near-infrared spectroscopy (NIRS) is increasingly used in this clinical scenario to monitor brain oxygenation. However, it is unknown whether perioperative cerebral NIRS monitoring and the subsequent treatment strategies are of benefit to patients. OBJECTIVES: To assess the effects of perioperative cerebral NIRS monitoring and corresponding treatment strategies in adults and children, compared with blinded or no cerebral oxygenation monitoring, or cerebral oxygenation monitoring based on non-NIRS technologies, on the detection of cerebral oxygen desaturation events (CDEs), neurological outcomes, non-neurological outcomes and socioeconomic impact (including cost of hospitalization and length of hospital stay)...

BACKGROUND: This study evaluates the morbidity, mortality, and cost differences between patients who underwent either a simple or a complex arterial switch operation. METHODS: A retrospective study of patients undergoing an arterial switch operation at a single institution was performed. Simple cases were defined as patients with d-transposition of the great arteries with usual coronary anatomy or circumflex artery originating from the right with either intact ventricular septum or ventricular septal defect...

OBJECTIVE/BACKGROUND: Epidemiological screening studies have demonstrated that the prevalence of abdominal aortic aneurysm (AAA) of Asian origin appears to be low and so increases uncertainty about the cost effectiveness of screening for AAAs in Chinese people. Some studies have demonstrated a higher prevalence of AAA in patients with atherosclerotic risk factors. The purpose of the study was to determine the prevalence of AAA and to explore the high risk group of AAA in Chinese patients with atherosclerotic risk factors...

External counterpulsation therapy was first developed over half a century ago as a resuscitative tool to support the failing heart and was based on hemodynamic principles of the intraaortic balloon pump. Over the course of last few decades, it has evolved into the modern enhanced external counterpulsation (EECP) therapy, which has proven to be a safe, effective, and low-cost noninvasive treatment for patients with debilitating angina and chronic heart failure who are poor candidates for revascularization procedures and have suboptimal results from other therapies...

The objectives of the African Organisation for Research and Training in Cancer (AORTIC), both at its inception in the early 1980s, and at its reactivation in 2000 following a decade of inactivity, included bringing the products of decades of advances in cancer research to African populations through international collaboration. The historical perspective provided in this report illustrates progress in achieving these objectives through successive continent-wide activities over a period of 30 years, culminating in the organisation's most recent conference held in Durban, South Africa, 21-24 November 2013...

Conventional angiography of the coronary arteries is a standard in heart and coronary arteries diagnosis, sufficient to choose a treatment method. The introduction of 64-row multidetector computed tomography improved the imaging of coronary arteries by increasing its spatial and temporal resolution. It has been shown that the potential clinical value of CT angiography, including dual source computed tomography (DSCT), is based particularly on the exclusion of coronary artery disease and is now a recognized clinical indication in patients with equivocal stress test results...

BACKGROUND: Lifelong surveillance is standard after endovascular repair of abdominal aortic aneurysm (EVAR), but remains costly, heterogeneous and poorly calibrated. This study aimed to develop and validate a scoring system for aortic complications after EVAR, informing rationalized surveillance. METHODS: Patients undergoing EVAR at two centres were studied from 2004 to 2010. Preoperative morphology was quantified using three-dimensional computed tomography according to a validated protocol, by investigators blinded to outcomes...

BACKGROUND: The UK has had universal free health care and public health programmes for more than six decades. Several policy initiatives and structural reforms of the health system have been undertaken. Health expenditure has increased substantially since 1990, albeit from relatively low levels compared with other countries. We used data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2010 (GBD 2010) to examine the patterns of health loss in the UK, the leading preventable risks that explain some of these patterns, and how UK outcomes compare with a set of comparable countries in the European Union and elsewhere in 1990 and 2010...

OBJECTIVE: To conduct an assessment on endovascular repair of descending thoracic aortic aneurysm (TAA). CLINICAL NEED: Aneurysm is the most common condition of the thoracic aorta requiring surgery. Aortic aneurysm is defined as a localized dilatation of the aorta. Most aneurysms of the thoracic aorta are asymptomatic and incidentally discovered. However, TAA tends to enlarge progressively and compress surrounding structures causing symptoms such as chest or back pain, dysphagia (difficulty swallowing), dyspnea (shortness of breath), cough, stridor (a harsh, high-pitched breath sound), and hoarseness...

OBJECTIVE: Atherosclerosis is a systemic disease, in which coronary and peripheral angiographies are required to be done at the same time in a large number of patients. To shorten the procedure time, and reduce complications, we tested the feasibility and the safety of using a single 5F multipurpose catheter, via transradial approach, for coronary, cerebral and renal angiographies. METHODS: One thousand and ninety-two patients were enrolled in the study. The procedure time, local vessel complications, duration of hospitalization, and costs were evaluated...

BACKGROUND: An abdominal aortic aneurysm (AAA) is potentially fatal when ruptured. Whereas the transthoracic echocardiography (TTE) protocol does not routinely include examination of the infrarenal abdominal aorta, the protocol is performed quickly and easily for AAA screening. AIM: The aim of this study was to evaluate the clinical utility of the protocol for AAA screening during TTE in a Korean population referred for clinical TTE. METHODS: All of the patients who were scheduled for TTE were enrolled in the study...

INTRODUCTION: A national AAA screening programme for men aged 65 is shortly to be implemented in England. Trials that have provided evidence for this screening programme have not included information on ethnicity. Hence their findings may not be applicable to ethnically diverse populations. REPORT: This study retrospectively looked at the prevalence of AAA in men aged 65, from different ethnic backgrounds in our city's current screening programme.19014 men (Caucasians n=18,431, Asian n=446, others n=137) were screened...

The isolated perfused mammalian heart preparation was established in 1897 by Oscar Langendorff. The method was developed on the basis of the isolated perfused frog heart established by Elias Cyon at the Carl Ludwig Institute of Physiology in Leipzig, Germany in 1866. Observations made using both methods at the end of the 19th and at the beginning of the 20th century led to important discoveries, forming the basis for our understanding of heart physiology. This included the role of temperature, oxygen and calcium ions for heart contractile function, the origin of cardiac electrical activity in the atrium, the negative chronotropic effect of vagus stimulation and the chemical transmission of impulses in the vagus nerve by acetylcholine...

Although advanced heart failure has been considered the main indication for heart transplantation, the increasing number of candidates and shortage of organs for transplantation, with accumulating waiting lists, has originated another look into more conventional surgery, previously considered of prohibitive risk. In fact, many cases are a result of anatomic lesions that can be corrected by conventional surgery, and in the past decade many surgical groups have obtained good and even excellent results in the treatment of aortic stenosis with low output, and in aortic and mitral regurgitation with severe left ventricular (LV) dysfunction...

BACKGROUND: For many years, cardiac auscultation has been the only available method for distinguishing between functional and organic murmurs; however, a more reliable differential diagnosis can now be achieved with Doppler echocardiography. The question remains as to whether a Doppler echocardiogram needs to be routinely recorded in the presence of a heart murmur or whether the auscultatory diagnosis of a functional murmur is sufficient. HYPOTHESIS: This prospective study attempts to answer this important question at a time when medical costs have to be curbed...

Congestive heart failure (HF) is a major focus of medical research. Its incidence has greatly increased in recent decades because of an aging population base and the increasingly successful treatment of other forms of chronic cardiac disease. Relevant large animal models of HF should reflect the complex interactions of cardiac dysfunction, neurohumoral dynamics and peripheral vascular abnormalities found in human HF. A number of large animal models have been developed, especially in dogs, sheep and swine, using naturally occurring HF, or single or combinations of interventions, as instruments to trigger the development of HF...

Vascular investigations by CT have experienced a decisive advance and found a high acceptance since the introduction of fast volume scanning (spiral CT). We have investigated the underlying physical foundations and optimized the operational aspects of the method now introduced as CT angiography (CTA). Investigations are carried out with a table feed of 1-10 mm/s. Images are reconstructed at 1-2 mm separations by use of algorithms which optimize the layer profile. The parameters must be adapted to the region being investigated...
