概括
双极射频导管切除 (Bi-RFCA) 有效地治疗与痕相关的心房间间隔膜心跳动 (IAS-ATs) 抗标准切除. 这种安全有效的方法在所有患者中实现了急性消除,复发率低.
科学领域:
- 电生理学
- 心血管医学
- 干预心脏病学
背景情况:
- 与痕相关的心房间间隔膜心跳动 (IAS-ATs) 对导管切除具有重大挑战.
- 在这些情况下,传统的单极射频导管切除 (RFCA) 可能是耐火的,需要采用替代策略.
研究的目的:
- 评估双极射频导管切除 (Bi-RFCA) 的安全性和有效性.
- 在患者的条件是耐受标准单极RFCA评估Bi-RFCA.
主要方法:
- 一项多中心研究包括17名与痕相关的IAS- AT耐单极RFCA患者.
- 使用两种穿过心膜隔膜的除导管进行双RFCA,功率高达40W,持续时间高达60秒.
- 主要结论是IAS-AT的急性终止和非诱导性.
主要成果:
- 在所有17名患者中,Bi-RFCA实现了针对性IAS- AT的急性消除.
- 在11个月的随访中,心房节拍/心房 (AT/ AF) 的复发率为12% (2名患者).
- 没有报告蒸汽爆发或程序/后续并发症.
结论:
- 双极射频导管切除 (Bi-RFCA) 是与痕相关的IAS-AT的安全有效治疗方法.
- 对传统单极RFCA无反应的患者,双极RFCA提供了可行的替代方案.
- 这种技术在治疗复杂心房动脉障碍方面显示出有前途的结果.

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
