■已确定使用POLARx™进行肺静脉隔离(波士顿科学,马尔伯勒,MA,美国)冷冻球囊是一种快速的,安全,和有效的方法。新款POLARx™FIT(波士顿科学公司),直径可从28毫米扩展到31毫米,目前可用。然而,在这种情况下,关于心房颤动治疗的证据有限.在这篇文章中,我们报告了使用POLARx™FIT对房颤患者进行冷冻球囊消融的一系列病例.
■该病例系列描述了三名患有不同形状和直径的肺静脉的患者的阻塞情况,这些患者接受了直径为31mm的球囊的冷冻球囊消融和肺静脉隔离。
■使用31mm模式的POLARx™FIT的冷冻球囊消融有可能为各种肺静脉几何形状提供安全稳定的肺静脉隔离,并具有良好的闭塞。在这个系列中,POLARx™FIT的31mm模式在左心房大和肺静脉大的患者中导致比28mm模式更好的肺静脉闭塞,包括左总肺静脉.这种方法可以被认为是心房颤动患者冷冻球囊消融的一线治疗选择。
UNASSIGNED: It is established that pulmonary vein isolation using the POLARx™ (Boston Scientific, Marlborough, MA, USA) cryoballoon is a rapid, safe, and effective approach. The new POLARx™ FIT (Boston Scientific), which is expandable from 28 to 31 mm in diameter, is currently available. However, there is limited evidence available regarding the treatment of atrial fibrillation in this setting. In this article, we report a
case series of cryoballoon ablation in patients with atrial fibrillation using POLARx™ FIT.
UNASSIGNED: This
case series describes a comparison of obstruction in three patients with pulmonary veins of different shapes and diameters undergoing cryoballoon ablation and pulmonary vein isolation with a 31 mm diameter balloon.
UNASSIGNED: Cryoballoon ablation using the 31 mm mode of POLARx™ FIT has the potential to provide safe and stable pulmonary vein isolation with good occlusion for a variety of pulmonary vein geometries. In this
case series, the 31 mm mode of the POLARx™ FIT resulted in better pulmonary vein occlusion than the 28 mm mode in patients with large left atria and large pulmonary veins, including the left common pulmonary vein. This approach may be considered a first-line therapy option of cryoballoon ablation in patients with atrial fibrillation.
