9《科技日报》电,美国加州大学旧金山分校研究人员24日在美国心脏协会期刊《循环》杂志上发表论文称,针对左心室的导管消融手术,会导致脑损伤,并可能会造成认知能力下降。这一结论与之前对导管消融手术安全性的认知存在明显差异。导管消融术是治疗心律失常的常用方法。医生会通过穿刺血管,把电极导管插入患者心脏,确定引起心律失常的异常结构位置后,在该处局部释放高频电流,通过热效能,摧毁病变组织,恢复并维持正常心律。导管消融术是一种微创手术,对心
In a paper published in the American Heart Association journal Circulation, researchers at the University of California, San Francisco, said that catheterization of the left ventricle causes brain damage and may cause cognitive impairment decline. This conclusion is distinct from the previous understanding of the safety of catheter ablation. Catheter ablation is a common method of treatment of cardiac arrhythmias. The doctor will insert the lead into the patient’s heart by puncturing the blood vessel, identify the abnormal structure that causes the arrhythmia, release the high-frequency current locally, and destroy the diseased tissue by the thermal effect to restore and maintain the normal heart rhythm. Catheter ablation is a minimally invasive surgery, the heart
