We describe 2 cases of complex coronary lesions in which the conventional 0.014-inch balloon catheters failed to cross a chronic subtotal occlusion and also failed to adequately predilate a calcified coronary lesion. The novel use of a 0.010-inch guidewire and compatible balloon catheters in both cases allowed us to perform the percutaneous coronary intervention (PCI) successfully, and we highlight the usefulness of these new devices as important adjunctive tools in PCI. (J Interven Cardiol 2011;24:315-319).
我们描述了 2 例复杂的冠状动脉病变，在这 2 例中，传统的 0.014 英寸球囊导管无法穿过慢性完全闭塞病变，也无法充分预扩张钙化的冠状动脉病变。在这 2 例中，我们创新性地使用 0.010 英寸导丝和与之相匹配的球囊导管，成功地进行了经皮冠状动脉介入治疗（PCI），我们强调这些新器械作为 PCI 的重要辅助工具的有用性。（J 介入心脏病学 2011；24:315-319）。
