title: Long-time inflation of the PTCA balloon.
abstract: For patients for whom the conventional percutaneous transluminal coronary angioplasty (PTCA) did not adequately improve stenosis, or sufficient angioplasty was impossible because of occurrence of dissection, we attempted using a long-time balloon inflation for more than 10 minutes. In order to allow the use of this balloon, we instituted an active rehabilitation program using a bicycle ergometer to promote the development of the collateral circulation up to the time of performing diagnostic angiography and PTCA, while attempting to use a perfusion balloon catheter for those patients not developing sufficient collateral circulation. Of the 134 patients undergoing PTCA, unsatisfactory angiographic results were obtained in 13 patients. Of these patients, long-time balloon inflation was performed in seven and primary success was achieved in six. From this study, we believe that the long-time balloon inflation in PTCA can improve the primary success rate and reduce postoperative complications.
