Percutaneous transluminal coronary angioplasty (PTCA) of heavily calcified rigid coronary arteries has decreased success and increased complication rates. Three cases are presented describing a new technique for the dilatation of severely calcified coronary arteries that were not dilatable by conventional angioplasty methods. This technique involves the use of a balloon dilatation catheter system parallel to a guide wire.
严重钙化的僵硬冠状动脉的经皮腔内冠状动脉成形术（PTCA）成功率降低且并发症发生率增加。本文介绍了3例病例，描述了一种用于扩张严重钙化冠状动脉的新技术，这些冠状动脉无法通过传统血管成形术方法扩张。该技术涉及使用与导丝平行的球囊扩张导管系统。
