[Uncommon indications for coronary angioplasty].
During the period between March 16, 1989 and October 7, 1992 at the Second Medical Clinic of the First Medical Faculty, Charles University Prague a total of 173 coronary angioplasties were performed. With expanding experience and greater availability of controllable super thin conductors and balloon catheters with a small profile, gradually the indication criteria of coronary angioplasty were extended. In 93.1% of patients simple balloon dilatation of a significant stenosis of the coronary arteries was performed and in 6.9% before dilatation in addition an attempt of recanalization of a chronic occlusion of the coronary artery was made. In 74% of the patients one coronary stenosis was dilated, in 16.7% several stenoses, in 1.2% of the patients a covered stenosis of the trunk of the left coronary was dilated and in the same number an aortocoronary bypass was performed. Even in the group of patients where only one coronary stenosis was dilated the type B coronary affection according to the classification ACC/AHA predominated and the same applied to the entire group of patients.
