概括

在心房动 (AF) 患者中,左心室较小 (LVD) 可能会降低射频导管切除 (RFCA) 的成功率. 患有较小的LVD和较高的H2FPEF得分的患者在RFCA后显示出明显较低的AF自由率.

科学领域:

心脏病学心脏病学
电力生理学电力生理学
医疗器械医疗器械

背景情况:

以前的研究将较小的左心室 (LVD) 与心房患者的不良结果联系起来.
需要进一步调查LVD大小对AF射频导管切除 (RFCA) 在偏激性AF (PAF) 的疗效的影响.
像H2FPEF一样,心力衰竭与保留射出分数 (HFpEF) 查得分,可能与切除后AF复发相关.

研究的目的:

调查左心室较小的阳性AF患者与较大的LVD患者相比,RFCA的益处较小.
探索LVD大小,H2FPEF得分和AF患者的RFCA成功率之间的关系.
分析专利卵孔 (PFO) 对患者特征的影响,与LVD大小相关.

主要方法:

对接受RFCA的133名AF/PAF患者的回顾性分析.
根据LVD中位数,患者被分为较小的LVD (<49毫米) 和较大的LVD (>48毫米) 组.
评估了临床随访和H2FPEF评分,以评估AF复发和患者特征.

主要成果:

较小的LVD和H2FPEF得分>5的患者与较大的LVD (80%;P=.037) 患者相比,具有显著较低的AF自由率 (50%) .
在LVD较小的患者中,H2FPEF得分>6的患者的AF无率较低 (50%) 与得分<6的患者相比 (79.4%;P=.039).
患有LVD>48mm和PFO的AF患者平均比没有PFO的患者年轻.

结论:

PAF RFCA的成功率受到左心室较小和H2FPEF得分较高 (≥6) 的组合的负面影响.
在特定的AF患者亚组中,较小的LVD可能表明RFCA的反应较差.
需要进一步的研究来阐明LVD和PFO在AF管理和切除结果中的作用.

Location and Orientation of the Heart

Location and Orientation of the Heart

The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Chambers of the Heart

Chambers of the Heart

The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

Mitral Stenosis I: Introduction

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
