Background: Artificial intelligence (AI) has the potential to improve echocardiography. However, AI systems may exhibit sex bias, reproducing societal stereotypes and performing worse for certain groups, potentially leadi...
Right ventricular-pulmonary artery uncoupling identifies higher risk of combined pulmonary hypertension in patients undergoing TAVR [0.03%]
右心室-肺动脉脱耦合可识别接受TAVR患者的联合性肺动脉高压高风险
Francesco Putortì,Tommaso Fabris,Consolato Mesiani et al.
Francesco Putortì et al.
Introduction: Right ventricular-pulmonary artery (RV-PA) uncoupling, expressed as the tricuspid annular plane systolic excursion/systolic pulmonary artery pressure (TAPSE/PAPs) ratio, is a negative prognostic indicator in...
Pulse Doppler ultrasound measurement of central artery elasticity: an exploratory study [0.03%]

Background: Arterial stiffness, as a biomarker of cardiovascular diseases, is most often described by a surrogate global stiffness index, pulse pressure wave velocity (PWV), a measure of the time for pressure pulses to tr...
Quantitative assessment of systolic and diastolic left ventricular energy loss using vector flow mapping in healthy participants: a retrospective observational study [0.03%]
健康受试者左心室收缩和舒张期能量损失的定量评估：回顾性观察研究
Naoyuki Otani,Haruka Noma,Harunori Takahashi et al.
Naoyuki Otani et al.
Background: Energy loss (EL) derived from vector flow mapping (VFM) is an indicator of intraventricular flow efficiency in the left ventricle. However, standardized reference values in adults have not been established. Fu...

Computer modeling to improve measurement of stroke volume with echocardiography [0.03%]
计算机建模提高超声心动图测量 Stroke Volume 的准确性
Sarah Balderston Murthi,Shiming Yang,Peter P Oliveri et al.
Sarah Balderston Murthi et al.
Background: The stroke volume (SV) can be measured by a human expert (HE) using the left ventricular outflow tract diameter (LVOTd) and its velocity time integral (VTI) with echo. If the SV is known, the cardiac output an...

Quantification of mitral regurgitation: from traditional methods to artificial intelligence [0.03%]
二尖瓣反流定量技术：从传统方法到人工智能
Kenneth Cho,Jimmy Su,Odile Bonnefous et al.
Kenneth Cho et al.
Mitral regurgitation (MR) is a common valvular disorder and associated with adverse outcomes. Echocardiography is the primary imaging modality for MR assessment; however, standard methods rely on geometric assumptions and single-frame analy...

Qin Lin et al.
Background: The prevalence of coarctation of the aorta is 4/10,000, accounting for 8% of congenital heart diseases. Accurate prenatal diagnosis of coarctation of the aorta is still difficult. ...
Intracardiac vs. Transesophageal echocardiography in left atrial appendage occlusion: real-world comparative effectiveness from a propensity-matched cohort [0.03%]
左心耳闭塞的经食道超声与腔内超声的疗效比较：倾向匹配队列的现实世界研究
Faizan Ahmed,Najam Gohar,Muhammad Hamza et al.
Faizan Ahmed et al.
Background: Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with a markedly increased risk of thromboembolic stroke, primarily originating from the left atrial appendage (LAA)...
Noise in clinical data: insights from assessment of aortic stenosis by echocardiography [0.03%]
超声心动图评估主动脉瓣狭窄的临床数据噪声分析及见解
Joshua N Lloyd,Guy P Armstrong
Joshua N Lloyd
Noise (synonyms: variability, imprecision) in clinical data is underappreciated. All measurements are affected by noise and bias. Research studies enrol many patients to average out noise and use randomisation and double-blinding to counter...
Surgical aortic valve replacement in severe left ventricular dysfunction: mortality, echocardiographic, and strain outcomes [0.03%]
严重左心室功能不全患者接受外科主动脉瓣置换术后的死亡率、超声心动图和应变结果
Roslan Aslannif,Si Ling Soh,Yee Sin Tey et al.
Roslan Aslannif et al.
Background: Patients with severe left ventricular (LV) dysfunction (ejection fraction [EF] ≤ 35%) undergoing surgical aortic valve replacement (SAVR) are considered high-risk patients. This study evaluated contemporary o...
