为解决传统单极射频导管消融 (RFCA)难以消除深部心肌关键组分所致室性心动过速 (VT)的临床难题，蒙特利尔Sacré-Coeur医院团队开展了一项采用多极映射导管作为心外膜回路电极的创新性研究。该研究通过猪模型证实，心内膜-心外膜多极射频消融可安全创建平均深度10.6±3.1mm的透壁性损伤 (93.5%组织 ...

RFCA significantly improved LVEF by a mean of 10.36 (CI: 8.75, 11.97, P < 0.00001) in patients with frequent PVCs from the RVOT.

In this study, the team used RFCA to treat 89 dogs with AP-related arrhythmia. While 23 breeds were represented, more than half of the patients were Labrador retrievers, as APs are more prevalent ...
