Preliminary experience with synchronized coronary sinus retroperfusion in humans.
Synchronized coronary sinus retroperfusion (SCSR) with arterial blood has been extensively tested in animals. This intervention offers temporary support to areas of ischemic myocardium while a method of definitive revascularization is being sought. The feasibility and safety of this procedure for patients with unstable angina was therefore tested. A No. 7F autoinflatable retroperfusion balloon ...
متن کاملTiming Attack: What Can Be Achieved by a Powerful Adversary?
Implementations of cryptographic algorithms often perform computations in non-constant time, due to performance optimizations. If such operations involve secret parameters, these timing variations can leak some information and, provided enough knowledge of the implementation is at hand, a careful statistical analysis could even lead to the total recovery of these secret parameters. This idea, d...
متن کاملDoes effective diastolic coronary venous retroperfusion depend on arterial-like blood pressure in the coronary sinus?
We therefore conducted a series of experiments in which we looked at the effects of retroperfusion on Yorkshire pigs (18 to 45 kg), anesthetized and instrumented as described previously.4 The retroperfusion system (model EC-I, USCI division of CR. Bard) was set to pump 35 to 40 ml. min-1 of arterial blood retrogradely into the coronary sinus starting just before a Z&minute occlusion of the left...
متن کاملIntermittent coronary sinus occlusion after coronary arterial ligation results in venous retroperfusion.
Coronary sinus occlusion retards necrosis of ischemic myocardium. To test the hypothesis that coronary sinus occlusion induces retrograde venoarterial flow, the coronary arteriovenous pressure gradient and the coronary arterial oxygen saturation were measured distal to a left anterior descending coronary artery ligature in dogs. In parallel, we constructed a mathematical model of known coronary...
متن کاملWhat can and cannot be achieved by advertising.
One of the names associated with advertising which is known outside the business, in addition to Saatchi and Saatchi, is David Ogilvy. He is a legendary figure who built up an agency of world renown which has only recently been bought by WPP Group plc. It is too early to say whether the new ownership will change much but we do know that the old agency was a remarkable one that borc the stamp of...
