概括
一个新的心磁共振 (CMR) 序列有效排除了大心房动 (AF) 患者的左心房附属体 (LAA) 血栓. 虽然对较小的血栓的准确性较低,但由于舒适度增加,患者更喜欢CMR而不是过食道心声扫描 (TEE).
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
背景情况:
- 左心房附属体 (LAA) 血栓是心房动 (AF) 中栓塞的主要原因.
- 过食管回声心脏图 (TEE) 是目前用于LAA血栓检测的标准.
- 非对比增强的心磁共振 (CMR) 提供了一个潜在的替代成像模式.
研究的目的:
- 为了比较一种新型非对比增强的CMR序列 (BOOST) 与LAA血栓检测TEE的疗效.
- 评估BOOST CMR在射频导管切除 (RFCA) 计划中的实用性,与对比度增强CT相比.
- 评估患者对TEE和CMR的主观经验.
主要方法:
- 试点研究招募了接受心脏转移或RFCA的AF患者.
- 程序前的TEE和CMR扫描用于LAA血栓和肺静脉评估.
- 对TEE和CMR经验的患者问卷;医生对CT与CMR的评估,用于RFCA规划.
主要成果:
- 在不包括LAA血栓 (94.4%) 中,TEE和CMR之间的高度一致性.
- 与TEE (67%) 相比,CMR的疼痛报告显著减少 (1.9%).
- 在91%的案例中,CMR图像被认为对RFCA规划有用,尽管图像质量低于CT.
结论:
- 该CMR BOOST序列显示了LAA血栓排除和RFCA规划的潜力.
- 该序列在检测较小的LAA瘤时可能受到限制.
- 由于改善舒适度,患者偏好强烈支持CMR而不是TEE.

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...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
