概括
在POLARx FIT冷却气球.
科学领域:
- 电子生理学 电子生理学
- 通过心脏切除术 (Cardiac Ablation) 进行心脏切除.
- 耳前的治疗方式 耳前治疗方法
背景情况:
- POLARx FIT冷却气球提供尺寸可调,但其对隔离区域和神经损伤 (PNI) 的影响需要进一步调查.
- 了解不同尺寸的冷气球的有效性对于优化心房动除手术至关重要.
研究的目的:
- 为了比较28毫米和31毫米POLARx FIT冷热气球对左心室 (LA) 和上静脉 (SVC) 隔离区域的影响.
- 在肺静脉 (PV) 隔离期间,评估与不同尺寸的冷热气球相关的神经损伤 (PNI) 的发生率.
主要方法:
- 分析了使用POLARx FIT冷藏气球治疗的31例心房动症病例.
- 评估SVC电压映射和隔膜袖长度在使用28毫米和31毫米气球进行切除之前和之后.
- 在不同的气球大小中,LA隔离区和PNI发病率的比较.
主要成果:
- 与28毫米气球相比,31毫米冷藏气球显著增加了LA后壁隔离面积 (p < 0.01).
- 使用31毫米气球 (p = 0.03) 观察到肺静脉右侧隔离区域的显著扩张.
- 随着气球尺寸的增加,SVC袖子长度逐渐缩短,在31毫米处理后显著减少 (p = 0.02). 没有发现气球大小和PNI之间存在一致的关联.
结论:
- 更大的31毫米POLARx FIT冷藏气球增强了LA后壁的隔离,并对SVC产生了更大的影响.
- 目前的发现表明,关于冷热气球大小与神经损伤发生率之间的关系的结果不一致.

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
