New coronary devices--atherectomy, laser angioplasty, and stents--have been designed to overcome main limitations of conventional balloon angioplasty (PTCA). So far, none of the new devices has clearly demonstrated a general superiority regarding acute complications. Late outcome and restenosis are not affected by the type of intervention, but mainly determined by the primary success, i.e. the safely obtained postprocedure lumen diameter. Although the new coronary devices may not replace conventional PTCA in "standard" situations, there are specific indications (venous bypass grafts, aorto-ostial lesions, complex calcified lesions) for atherectomy, laser angioplasty, and stents with better acute results compared to PTCA. Since the best post-procedural result determines the extent of restenosis, it is crucial to select the appropriate device for special lesions or acute complications.
新型冠状动脉介入器械——旋切术、激光血管成形术和支架——旨在克服传统球囊血管成形术（PTCA）的主要局限性。到目前为止，尚无一种新型器械在急性并发症方面明确显示出总体优越性。晚期预后和再狭窄不受干预类型的影响，主要取决于初次成功情况，即术后安全获得的管腔直径。尽管新型冠状动脉介入器械在“标准”情况下可能无法取代传统PTCA，但对于旋切术、激光血管成形术和支架，在某些特定适应症（静脉旁路移植血管、主动脉开口病变、复杂钙化病变）中，与PTCA相比，其急性效果更好。由于术后最佳效果决定了再狭窄的程度，因此为特殊病变或急性并发症选择合适的器械至关重要。
