title: [A new procedure for the study and treatment of myocardial infarction in the acute phase: percutaneous coronary angioscopy].
abstract: The recent development of small diameter optical fibers, which are also very flexible allows us to realise percutaneous coronary angioscopy. First of all we visualized normal dog's arteries, bifurcations, origin of small branches; then we created and visualized intimal tears, dissections and experimental thrombi. The second part of this work consisted in applying this new technic in three patients who had an evolving myocardial infarction and an occluded right coronary artery. In all three cases a clot has been visualized, occluding the lumen of the artery. This small experiment shows that percutaneous angioscopy is a feasible, quick and save procedure. Its developments will be very important according to the development of percutaneous interventional therapies.
