Comparative Study[Results of coronary artery bypass grafting with left ventricular dysfunction (comparison of off-pump versus on-pump)].
The aim of this study was to compare the results of myocardial revascularisation with or without cardiopulmonary bypass in patients with impaired left ventricular function. ⋯ Off-pump coronary artery bypass surgery provides satisfactory operative results for most patients with reduced left ventricular function. Prospective and randomly study will be necessary before concluding.

Comparative Study[Pressure wave shape comparison between two non-invasive tonometric devices].
Pulse wave analysis is a pivotal instrument to estimate central hemodynamic parameters. Applanation tonometry on radial and/or carotid arteries is usually used to detect pressure waveforms. Available commercial devices have been validated against invasive catheterism, showing a good agreement of harmonics pattern. In a previous investigation, we observed differences on radial second systolic peak (rSPB2) between two commonly used devices: SphygmoCor (AtCor, Australia) and PulsePen (Diatecne, Italy). The aim of our study was to further quantify differences on radial and carotid signals from the two devices. ⋯ PulsePen and SphygmoCor sensors are not equivalent and provide different wave shapes. These differences on wave shape have important consequences on parameters computed from these waveforms with more discrepancy on radial derived parameters such as rSBP2 and mean arterial pressure than on carotid derived parameters. Further studies are required to compare invasive pressure parameters to indices derived from these two devices.

[Surgery of aortic regurgitation with reduced left ventricular function].
Aortic valve replacement improves clinical symptoms and left ventricular systolic function in patients with chronic aortic regurgitation despite a higher surgical risk. The objective of this study is to determine if left ventricular function will be normalized after surgery. ⋯ Despite reduced left ventricular systolic function, aortic valve replacement in chronic aortic regurgitation was associated with acceptable operative risk. Surgery improves functional status, symptoms and ejection fraction in most patients.

Review[Therapeutic hypothermia and management of sudden death].
Due to its protective effects on the brain and potentially the myocardium, cooling therapy is clearly part of the standard of care of any sudden death especially in the setting of myocardial infarction. Recent guidelines recommend cooling therapy (32 to 34 °C) for 12 to 24 hours in unconscious patients with spontaneous circulation after resuscitated sudden death. We provide here a review of clinical evidence, cooling techniques and potential adverse effects of cooling therapy.

Improvement of myocardial reperfusion with a greater use of primary percutaneous coronary intervention, adjunctive pharmacological and mechanical therapies have contributed to a spectacular decrease in mortality of patients presenting with ST-elevation myocardial infarction.
