[Transluminal coronary angioplasty performed in patients with single vessel disease of the right coronary artery disease. Long-term results].

The patients who have only single vessel disease of the right coronary artery have an excellent prognosis, unaffected by surgery. The object of this study was to evaluate the long-term prognosis of these patients after transluminal coronary angioplasty. The criteria of analysis were survival, anginal symptoms, quality of life and ergometric parameters.

[Qualitative and quantitative descriptions of the mechanisms of action of the angioplasty balloon on coronary stenosis. An endovascular ultrasonic study].

The barotrauma induced by inflation of the balloon on an obstructive atherosclerotic plaque induces several distinct, complex effects. The object of this study was to describe these mechanisms based on endovascular echographic sections of coronary stenoses before and after balloon angioplasty. The 32 lesions analysed were richly cellular (81.
