title: [On 23 cases of postinfartual interventricular septal rupture surgically treate. Immediate e long term results (author's transl)].
abstract: An experimental study on myocardial viability after acute occlusion of the left anterior descending coronary artery (LAD) for period of six hours is described. For this study 24 adult dogs were used in which an acute myocardial infarction for an area of 20-30% of left ventricul were obtained with ligatures completely occluding the LAD and his collaterals. Following ligature release, on the LAD only, ECG, BP, VCP and histology were studied with the general clinical conditions. The Authors affirm that clinical and ECGraphic data became worse after reperfusion; instead histological data show the possibility of recovery of many muscolar cells of ischemic and neighbouring areas.
