业已显示左心室乳头肌是伴或不伴心脏结构异常患者心律失常的潜在起源部位。与其他部位室性心律失常比较,这些区域的心律失常消融操作困难、导管稳定性差,但已有导管消融有效的报道。本研究借助心腔内心脏超声和图像整合,比较左心室乳头肌起源室性心动过速或期前搏动的冷冻和射频消融手术结果及复发率。回顾性分析连续189例因症状性持续性室性心动过速、阵发性室性心动过速或室性期前搏动接受射频导管消融的
Left ventricular papillary muscle has been shown to be a potential source of arrhythmias in patients with or without cardiac structural abnormalities. Compared with other parts of the ventricular arrhythmia, arrhythmia ablation in these areas difficult operation, poor catheter stability, but the catheter ablation has been effective reports. In this study, intracardiac echocardiography and image integration were used to compare the results of cryoablation and radiofrequency ablation and the recurrence rate of ventricular tachycardia or anterior beat of left ventricular papillary muscle. A retrospective analysis of 189 consecutive patients with symptomatic persistent ventricular tachycardia, paroxysmal supraventricular tachycardia or ventricular premature beat accept radiofrequency catheter ablation
