[Computer analysis of a method of myocardial protection used in a series of 547 operations under extracorporeal circulation in adults].
During 4 years (1970-1974), the numerous pre, per and post-operative datas collected for each adult operated under E.C.C. by the same surgeon, have been analysed on computer (547 cases). The myocardic protection method was unvariable: steady hypothermia of 30 degrees C, induced ventricular fibrillation, myocardic anoxia time less than 15 mn, strict out-bubbles of the left cavities. A direct perfusion of the coronary arteries has been used in case of aortotomy. Analysis of the early post-operative mortality causes and of the various post-operative myocardic complications did not reveal any baneful influence of this myocardic protection method. The average post-operative left auricular pressure, the most reliable test of the left ventricular dynamics, or its post-operative variations are independent of the ventricular fibrillation time, the perfusion time or the coronal output used.
