Electieve angioplastiek van totaal afgesloten coronairarteriën zonder acuut myocardinfarct: resultaten op korte en lange termijn

– Of 951 consecutive patients referred for coronary angioplasty between September 1980 and December 1984, 80 patients presented with total of functional occlusion of the involved vessel. In 54 patients the total or functional occlusion represented a progression, without myocardial infarction, of a previously diagnosed stenotic lesion.

For the whole group, angioplasty was successful in 46 patients (58). The primary success rate with the functional occluded vessel (76) was significantly higher than with the total occlusion (45). The duration of the occlusion had also a clear influence on the outcome of the angioplasty. Of the 46 patients in whom angioplasty was successful, 15 patients had recurrence of symptoms during follow-up (3-48 months). Eight were kept on medical treatment, 3 required bypass surgery and 4 underwent repeat percutaneous transluminal coronary angioplasty (PTCA). After initial success, late angiographic studies performed in 32 of 46 patients showed reocclusion in nine.
