Cardiac myxoma are the most common primary heart tumor. It accounts for 40-50% of primary cardiac tumor. Approximately 75% occurs in left atrium and 15-20% in right atrium. Myxoma are usually polypoid, pedunculated lesion with smooth surface covered with thrombus. Most common site of attachment is at the border of fossa ovalis in left atrium but it can occur in any part of atrial wall. Symptoms are produced because of mechanical obstruction with cardiac blood flow, tumor embolization and constitutional symptoms due to increased expressions of IL-6. Echocardiography is the best diagnostic modality to localise the tumor. Surgical excision is the mainstay of treatment of myxoma present in any location.

ImagingIntroductionMR contrast media have become an indispensable part of magnetic resonance (MR) imaging, but their roles in ablation therapies are still controversial. The interactions between physical/biological properties of MR contrast media (Longitudinal=T1, transverse=T2 and susceptibility=T2* relaxation times) and diseased tissues (perfusion, edema, hemorrhage and coagulative necrosis) play important roles in differentiating pathologic and ablated tissues.

Fatal arrhythmia is the leading cause of mortality in chronic haemodialysis patients. Long QT syndrome is responsible for polymorphic ventricular tachycardia known as Torsade de Pointes. Classically, long QT syndromes were divided into congenital and acquired; however ‘silent’ variants, in which patients remain asymptomatic until exposed to a drug or electrolyte disturbance precipitating the arrhythmia, have now been recognized.

Opinion is divided as to the changes in ventricular function brought about by exercise, with few studies on water-based exercise programmes for heart-failure patients. This study investigates whether following a partial water-based exercise programme could lead to an earlier improvement in ventricular function in heart-failure patients compared with a land-based exercise programme.

Statistics across industrialised societies show that occupational stress results in social and financial costs for individuals, organisations, and economies. Occupational stress is prevalent in many different forms, for example, work intensification, dissatisfaction with current work schedules, feelings of job insecurity, more work being done at odd hours, the spread of new information and communication technologies, and long hours becoming more common.
