2. 1. Effect of valve replacement for aortic stenosis on ventricular function

   Author : Ying Zhao; Michael Henein; Per Lindqvist; Eugenio Picano; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; aortic valve replacement; echocardiography; speckle tracking; exercise echocardiography; ventricular function; septal radial motion; twist; displacement; strain; strain rate;

   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

4. 2. New insights in the assessment of right ventricular function : an echocardiographic study

   Author : Avin Calcutteea; Michael Y Henein; Per Lindqvist; Jan Engvall; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; echocardiography; right ventricle; ischaemic heart disease; pulmonary hypertension; aortic stenosis; aortic valve replacement; three dimensional echocardiography; speckle tracking echocardiography; Cardiology; kardiologi;

   Abstract : Background:  The right ventricle (RV) is multi-compartmental in orientation with a complex structural geometry. However, assessment of this part of the heart has remained an elusive clinical challenge. READ MORE

5. 3. Strain echocardiography in cardiac surgery - studies on the effects of loading conditions and inotropic agents on myocardial contraction and relaxation

   Author : Martin Fredholm; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; strain echocardiography; right heart catheterization; cardiac surgery; heart failure; levosimendan; milrinone; left ventricular function; right ventricular function; systole; diastole; preload; afterload; pacing; longitudinal function; ventricular dimensions; ventricular interdependence;

   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.

6. 4. The important role of left atrial function parameters in clinical practice

   Author : Ibadete Bytyci; Michael Y. Henein; Roxy Senior; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left atrial function; Left atrial compliance; left atrial stiffness; Clinical practice; kardiologi; Cardiology;

   Abstract : The aim of this thesis is to evaluate the role of left atrial function in clinical practice based on the following studies:1)    Determining left atrial (LA) structure and myocardial function measurements that predict pulmonary capillary wedge pressure (PCWP).2)    Identifying predictors of exercise capacity in patients with HFpEF and right ventricle (RV) dysfunction.

7. 5. Novel insights into echocardiographic assessment of cardiac function following heart surgery

   Author : Nashmil Hashemi; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Assessment of cardiac function is a fundamental in everyday clinical decision making and is essential diagnostic tool for choosing therapy in patients with cardiac disease. Currently, echocardiography is the integral part in management of patients with different cardiac disease and the most established imaging tool in the assessment of cardiac function. READ MORE
