[Infarction with late disappearance of the Q wave. Apropos of 30 cases].
A selective coronary arteriography was performed in 30 subjects with myocardial infarction, after disappearance of the necrosis wave. The angiographic characteristics of this group when compared with a series of infarctions, unselected by the clinical course, wers: a decreased severity index; a better development of the compensatory circulation; and a lesser frequency of severe disturbances of ventricular dynamics. Disappearance of the Q wave might be explained by a very distal occlusion in 2 cases, by a recanalization in 4 cases and by a very intense development of the collateral circulation in 8 cases. One subject had a normal coronary arteriography.
