Caroline Weytjens,Bernard Cosyns,Jan D&#x;hooge et al.
Caroline Weytjens et al.
Aim: Limited data are available about the use of Doppler myocardial imaging (DMI) in small animals. We intend to provide reference values for velocity, strain and strain rate in a large group of healthy rats and studied t...
The use of the right ventricular diameter and tricuspid annular tissue Doppler velocity parameter to predict the presence of pulmonary hypertension [0.03%]
采用右室径和三尖瓣环组织多普勒速度参数预测肺动脉高压患者的临床价值研究
Anthony S McLean,Iris Ting,Stephen J Huang et al.
Anthony S McLean et al.
Aims: Detecting the presence of pulmonary hypertension (PH) is important especially with unexplained dyspnoea and suspected thromboembolism. Although PH can be detected invasively by right ventricular (RV) catheterisation...
N-terminal proBNP levels in patients with Chagas disease: a marker of systolic and diastolic dysfunction of the left ventricle [0.03%]
查加斯病患者血浆脑钠肽水平与左心室收缩舒张功能不全的关系研究
Marcia M Barbosa,Maria do Carmo P Nunes,Antônio Luiz P Ribeiro et al.
Marcia M Barbosa et al.
Aims: NT-proBNP levels are known to be elevated in systolic and diastolic dysfunction. Doppler indices of diastolic dysfunction (DD) have been shown to have prognostic value in patients with Chagas' cardiomyopathy (CC). H...

Kivilcim Ozden et al.
Pulmonary atresia and ventricular septal defect (PA-VSD) with major aortopulmonary collaterals (MAPCAs) is a complex and extremely heterogeneous anomaly. PA-VSD with both pulmonary arteries originating from systemic arterial circulation wit...
Prominent crista terminalis and Eustachian ridge in the right atrium: Two dimensional (2D) and three dimensional (3D) imaging [0.03%]
右心房显著的终末嵴和欧氏嵴：二维和三维成像
Tanya McKay,Liza Thomas
Tanya McKay
The crista terminalis and Eustachian ridge are normal anatomical structures within the right atrium that are not normally looked for or visualised in the standard views obtained while performing a transthoracic echocardiogram (TTE). In this...
