Cardiac disease is not easy to recognise in general practice. An echocardiogram is an excellent way to provide information about left ventricular mass and diastolic (dys)function and the presence of valvular heart disease. To improve diagnostic care of cardiac patients, an open access echocardiography service was established in the referral ...

Ventricle-pulmonary artery connections in patients after the Fontan procedure lead to ineffective volume loading and can cause long term problems. In patients with a cavopulmonary shunt anterograde pulmonary blood flow is frequently maintained, but can cause significant volume loading of the heart or complicate the subsequent Fontan procedure. To evaluate ...

PURPOSE OF REVIEW: Perioperative cardiac risk reduction using perioperative beta-blockade is being widely adopted. Recent research has identified a second-line agent, perioperative clonidine, that can be used to reduce the risk of perioperative cardiac mortality. Perioperative clonidine has some advantages over perioperative beta-blockers because it has less risk of bronchospasm ...

BACKGROUND: Autonomic dysfunction contributes to orthostatic intolerance in vasovagal syncope (VVS), but as it has not been identified by spectral analysis of heart rate variability (HRV) in previous studies, the present hypothesis was that nonlinear analysis of HRV would identify the orthostatic intolerance in VVS. METHODS AND RESULTS: Twenty-six patients ...

An increasing body of evidence from laboratory and clinical studies suggests that vasopressin may represent a promising alternative vasopressor for use during cardiac arrest and resuscitation. Current guidelines for cardiopulmonary resuscitation recommend the use of adrenaline (epinephrine), with vasopressin considered only as a secondary option because of limited clinical data. ...

BACKGROUND: Hypothermia is defined as a core temperature of less than 35 degrees C. The decision to resuscitate a hypothermic patient can be difficult, as consideration must be given to whether the patient died before the cooling process. The modality for rewarming must also be considered. CASE REPORT: A severely ...
