ReviewRemote ischemic preconditioning: the surgeon's perspective.
Since cardiac surgery began, surgeons have aimed to find methods of minimizing myocardial injury resulting from ischemia and reperfusion. The concept of somehow conditioning the heart in order to attenuate ischemia and reperfusion-related injury has evolved in cardiovascular research over decades, from ischemic preconditioning and postconditioning to, more recently, remote ischemic preconditioning (and postconditioning). ⋯ To date, the translation of this powerful innate mechanism of myocardial and/or multiorgan protection from the animal lab to the operating theatre, using transient occlusion of blood flow to the upper limb with a blood-pressure cuff before cardiac surgery, has shown promising results, with several proof-of-principle and first randomized controlled clinical trials reporting benefits for patients undergoing cardiac surgery. If the efficacy of remote ischemic preconditioning can be conclusively proven, the clinical applications in cardiac surgery could be almost infinite, providing multiorgan protection in various surgical scenarios.

Review Historical ArticleGenesis of remote conditioning: action at a distance--'hypotheses non fingo'?
Remote ischemic preconditioning is the phenomenon whereby brief episodes of ischemia-reperfusion applied in a distant organ or tissue render the myocardium resistant to infarction. The discovery of remote conditioning was not a serendipitous finding, but, rather, was predicted by mathematical modeling. In the current review, we describe how the hypothesis for remote conditioning was formulated and tested, how the paradigm has expanded to encompass a spectrum of remote triggers, and summarize the progress that has been made in elucidating the mechanisms responsible for this intriguing form of cardioprotection.

Comparative StudyEchocardiography-guided versus fluoroscopy-guided temporary pacing in the emergency setting: an observational study.
The insertion of a temporary pacemaker can be a lifesaving procedure in the emergency setting. ⋯ Echocardiography-guided temporary pacemaker is a well-tolerated procedure that could allow reliable insertion of a temporary pacemaker; therefore, it is a well-tolerated option in an emergency setting and in hospitals where fluoroscopy is not available.
