Stentablation (SA) has been used as a bailout method for undilated, under-expanded stents, but one reason that SA is associated with a high rate of major adverse cardiac events may be its adverse effect on microcirculation. Consequently, appropriate lesion preparation should always be considered for heavily calcified lesions to avoid such complications.
Under-expansion of the coronary stent is associated with increased rates of in-stent restenosis and thrombosis. Stentablation (SA) with rotational atherectomy is used in the treatment of undilatable, under-expanded coronary stents; however, its effect on coronary microcirculatory function remains unclear. This novel report compares microcirculation indices before and after SA.
支架消蚀术（SA）已被用作未扩张、扩张不足支架的补救方法，但SA与主要不良心脏事件发生率高相关的一个原因可能是其对微循环的不良影响。因此，对于严重钙化病变应始终考虑进行适当的病变预处理，以避免此类并发症。
冠状动脉支架扩张不足与支架内再狭窄和血栓形成率增加相关。采用旋磨术的支架消蚀术（SA）用于治疗不可扩张、扩张不足的冠状动脉支架；然而，其对冠状动脉微循环功能的影响仍不清楚。本新报告比较了SA前后的微循环指标。
