目的:观察肺静脉(PV)消融后左房(LA)水肿的发生率和严重程度以及其对心脏功能的影响。背景:虽然广泛的LA导管消融已被证实对阵发性房颤(PAF)的效果优于肺静脉口节段性电隔离(S-PVI),但是它可能会带来一些危及生命的并发症,其中包括伴有LA水肿的充血性心力衰竭。方法:分别有50例和27例患者接受了S-PVI(S组)和环PV心房消融(C组)以治疗经药物治疗无效的PAF。所有患者在PV消融前、消融后1d或2d及1个月后接受增强电子束CT扫描(EBT),并在PV消融1个月后接受经胸超声心动图(UCG)检查。
PURPOSE: To observe the incidence and severity of left atrium (LA) edema after pulmonary vein (PV) ablation and its effect on cardiac function. BACKGROUND: Although extensive LA catheter ablation has been shown to be superior to pulmonary vein ostial segmental galvanic isolation (S-PVI) in patients with paroxysmal atrial fibrillation (PAF), it may introduce some life-threatening complications Including congestive heart failure accompanied by LA edema. Methods: S-PVI (Group S) and atrial PV atrial ablation (Group C) were treated in 50 and 27 patients, respectively, to treat ineffective PAF. All patients received enhanced electron beam computed tomography (EBT) 1 or 2 days and 1 month after ablation prior to PV ablation and transthoracic echocardiography (UCG) 1 month after PV ablation.
