概括

胸前回声心脏成像 (TTE) 的图像质量在心力衰竭患者中通常很差,特别是在前壁. 这凸显了需要更好的心声回声学家培训和关注技术细节的需要,以准确诊断.

科学领域:

心脏病学心脏病学
医疗成像医学成像
心声回声扫描 (Echocardiography) 是一种心声回声扫描.

背景情况:

胸前回声心脏成像 (TTE) 的图像质量低,损害了诊断的准确性.
评估TTE图像质量对于可靠的心脏评估至关重要,特别是在心力衰竭 (HF) 中.

研究的目的:

开发一个框架来评估TTE图像质量在角视图 (2,3,和4室).
使用此框架,在心力衰竭 (HF) 患者中描述细分级可视化模式.
在这个患者群体中确定与TTE图像质量差相关的风险因素.

主要方法:

一项横截面研究分析了230名正在接受ICD/CRT植入评估的患者的268次TTE检查.
使用一种新的框架来评估顶点视图中的图像质量,计算每个细分段的平均得分.
对图像质量差的风险因素是根据患者人口统计学,临床和心声数据进行评估的.

主要成果:

开发的框架显示出高的内部可靠性 (类内相关系数>0.9).
前面和前侧壁显示出最差的图像质量,而较低的部分则可视化得最好.
仅在65%的病例中才能实现充分的可视化 (≥5个内心边界段),与较高的BMI,BSA,HF风险因素和心脏异常相关的挑战.

结论:

在被考虑进行CRT-D/ICD植入的患者中,跨胸腔心声成像 (TTE) 的成像挑战很普遍.
图像质量差与特定的患者特征有关,包括肥胖和糖尿病和心房动等并发症.
加强心声回声学家培训和对技术方面的仔细关注对于改善常规实践中TTE图像质量至关重要.

关键词:

Quality Control

Quality Control

Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Quality Assurance

Quality Assurance

Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

Quality of Water

Quality of Water

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

Nursing Process for Patient and Caregiver Teaching I: Assessment and Diagnosis

The nursing process provides a clinical decision-making framework for patients and families to establish and implement a personalized care plan. Since part of the nurse's duties is to teach patients, the steps of the nursing process are the most effective way to approach instruction. The nursing process and the teaching-learning process are inextricably linked.
It is critical to determine the patient's learning needs during the assessment. Determination of learning needs compounds data...

Pulse amplitude and quality

Pulse amplitude and quality

Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

Testing Water Quality

Testing Water Quality

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
