Tissue Doppler imaging following paediatric cardiac surgery : early patterns of change and relationship to outcome [PDF]
, 2009 In this study, tissue Doppler imaging (TDI) was used to assess changes in ventricular function following repair of congenital heart defects. The relationship between TDI indices, myocardial injury and clinical outcome was explored.

An electrooptical muscle contraction sensor [PDF]
, 2010 An electrooptical sensor for the detection of muscle contraction is described. Infrared light is injected into the muscle, the backscattering is observed, and the contraction is detected by measuring the change, that occurs during muscle contraction ...

Effect of the contraction ratio upon viscoelastic fluid flow in three-dimensional square-square contractions [PDF]
, 2011 In this work we investigate the laminar flow through square–square sudden contractions with various contraction ratios (CR¼2.4, 4,8and12), using a Newtonian fluid and a shear-thinning viscoelastic fluid.

Left ventricle ejection fraction and strain derived by three-dimensional echocardiography are associated with exercise capacity in the patients with heart failure [PDF]
Vojnosanitetski Pregled, 2019 Background/Aim. Echocardiography represents the most commonly performed noninvasive cardiac imaging tests for the patients with heart failure (HF). The aim of this study was to assess the relationship between the exercise capacity parameters [peak oxygen
