Background: Life-threatening arrhythmias (LTAs) can trigger sudden cardiac death or provoke implantable cardioverter-defibrillator (ICD) discharges that escalate morbidity and mortality. Longitudinal myofibrils predominate in the subendocardium, which is uniquely sensitive to arrhythmogenic triggers. In this study, we test the hypothesis that mitral annular systolic velocity (S'), a simple routinely obtained tissue Doppler index of LV long-axis systolic function, might predict lethal arrhythmias irrespective of left ventricular ejection fraction (LVEF).

Objectives: Congestion is associated with worse outcomes in critically ill surgical patients but can be difficult to quantify noninvasively. We hypothesised that plasma volume status (PVS), estimated preoperatively using a validated formula that enumerates percentage change from ideal plasma volume (PV), would provide incremental prognostic utility after coronary artery bypass graft (CABG) surgery.

Methods: In this retrospective cohort study, patients who underwent CABG surgery (1999-2010) were identified from a prospectively collected database.

Background: A hernia repair open surgical simulation computer software was developed at Imperial College London. A randomized controlled educational trial was conducted to investigate the benefit of the simulation on the development of procedural knowledge.

Methods: Medical students in their clinical years were invited to participate in the trial.
