1. Ventricular rotation and the rotation axis : a new concept in cardiac function
Abstract : Background: The twisting motion of the left ventricle (LV), with clockwise rotation at the base and counter clockwise rotation at the apex during systole, is a vital part of LV function. Even though LV rotation has been studied for decades, the rotation pattern has not been described in detail. READ MORE

2. Insights into the effect of myocardial revascularisation on electrical and mechanical cardiac function
Abstract : Background: Acute coronary syndrome is known for its effect on cardiac function and can lead to impaired segmental and even global myocardial function. Evidence exists that myocardial revascularisation whether pharmacological, interventional or surgical results in improvement of systolic and diastolic left ventricular (LV) function, particularly that of the long axis which represents the sub-endocardial function, known as the most sensitive layer to ischaemia.

3. Strain echocardiography in cardiac surgery - studies on the effects of loading conditions and inotropic agents on myocardial contraction and relaxation
Abstract : Background: Although reductions in myocardial contractility and relaxation are key compo-nents in heart failure (HF), assessment of them is difficult, as clinical measurements deal with a net effect of myocardial contractility, heart filling (preload), outflow impedance (afterload) and heart rate (HR). Echocardiographic (echo) deformation parameters, like strain (myocardial shortening) and strain rate (the speed of deformation, SR), have been proposed to more accu-rately measure myocardial function, but incongruent previous studies have raised concerns that they may be load-dependent.

4. Effect of valve replacement for aortic stenosis on ventricular function
Abstract : Background:Aortic stenosis (AS) is the commonest valve disease in the West. Aortic valve replacement (AVR) remains the only available management for AS and results in improved symptoms and recovery of ventricular functions. READ MORE

5. Right ventricular function in pulmonary embolism
Abstract : Patients with pulmonary embolism (PE) and right ventricular (RV) dysfunction are known to be at risk of in-hospital clinical worsening and PE-related mortality. Even in patients with a preserved systemic arterial pressure, the RV dysfunction indicates a higher risk, thus affecting the patients’ level of care and the therapeutic approach. READ MORE
