A short 80% peripheral stenosis of the anterior interventricular branch which remained unchanged for nine years was successfully dilated by transluminal balloon coronary angioplasty using long-wire technique with angiographically demonstrated reduction of the stenosis to 30%. The patient has since been without symptoms, even on severe physical exertion. It has previously been thought that increasing hardening of the atheroma of a long-standing stenosis prevented successful lasting dilatation.
前室间支80%的短段周围性狭窄持续九年未变，采用长导丝技术经皮腔内冠状动脉成形术成功扩张，血管造影显示狭窄程度降至30%。此后患者一直无症状，即使在剧烈体力活动时也是如此。此前人们一直认为，长期狭窄的动脉粥样硬化不断加重会妨碍成功持久的扩张。
