概括

对心房动 (AF) 进行重复切除,将肺静脉隔离 (PVI) 与针对低电压区域 (LVA) 的基质修改结合起来是有效的. 这种方法解决了PV重新连接和LVA,改善了复发性AF患者的治疗结果.

科学领域:

电力生理学电力生理学
心脏病学心脏病学
医疗器械医疗器械

背景情况:

在初始肺静脉隔离 (PVI) 后,复发性心房 (AF) 是一个重大的临床挑战.
识别和解决简单的PVI以外的基础基质对于改善切除成功率至关重要.

研究的目的:

通过PVI和基质左心房切除的联合策略,评估重复AF切除的疗效和安全性.
专门针对PVI后复发性AF患者的低电压区域 (LVA).

主要方法:

在PVI后复发AF的患者接受了重复手术,包括在鼻腔节律期间的电压映射.
肺静脉重新连接得到了解决,如果确定LVA (<0.5mV),则通过线性或盒子病变进行基质修饰.
在6个月的时间里,使用基于智能手机的光电显微镜应用程序对心律失常的复发进行了监测.

主要成果:

在84.5%的患者中观察到肺静脉重新连接,而LVA在53.4%的患者中存在.
患有LVA的患者更有可能是老年人,女性,并且左心房体积更高.
虽然LVA患者 (48.4%) 与没有LVA患者 (66.7%) 相比,无心律乱的生存率较低,但综合方法被认为是有效和安全的.

结论:

肺静脉重新连接和LVA的存在是重复AF切除手术中的关键发现.
重复PVI与针对LVA的量身定制基质修改相结合,证明了治疗复发性心房动的有效性和安全性.

关键词:

Dysrhythmias VI: Management of Dysrhythmias

Dysrhythmia management involves a multifaceted approach, incorporating pharmacological treatments, medical procedures, surgical interventions, lifestyle modifications, and patient education.Pharmacological ManagementAntiarrhythmic Drugs:Class I (Sodium Channel Blockers): This class includes quinidine and procainamide, which reduce the speed of impulse conduction in the heart, stabilize the cardiac membrane, and control arrhythmias. Quinidine and procainamide are Class IA agents that prolong the...

Dysrhythmias V: Evaluating Dysrhythmias

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...
