2. 1. Left Ventricular Dynamics During Exercise in Endurance Athletes

   Author : Milena Sundstedt; Tommy Jonason; Egil Henriksen; Eva Nylander; Uppsala universitet; []
   Keywords : Physiology; athletes; exercise; left ventricular dynamics; stroke volume; mitral annular motion; Fysiologi;

   Abstract : Large quantities of data have described left ventricular adaptation to endurance training, but basic concepts on left ventricular performance during exercise remain controversial. In this thesis, we present the results of studies of left ventricular dynamics during exercise in 89 endurance-trained athletes. READ MORE

4. 2. Lung Emphysema & Cardiac Function

   Author : Kirsten Jörgensen; Göteborgs universitet; []
   Keywords : emphysema; hemodynamics; ventricular end-diastolic volumes; lung volume reduction; ventricular function; transoesophageal echocardiography; magnetic resonance imaging; diastole; simendan; hypertrophy;

   Abstract : Patients with severe lung emphysema have poor quality of life because of impaired lung function and reduced exercise tolerance. Concomitant heart disease in severe emphysema is well recognised. The prevailing view is that mainly the right side of the heart is involved, while the issue of left ventricular (LV) involvement is less studied. READ MORE

5. 3. Treatment of Right Ventricular Failure through Partial Volume Exclusion : An Experimental Study

   Author : Per Vikholm; Laila Hellgren; Lund Lars; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Right Heart Failure; Left Ventricular Assist Device; Glenn shunt; Thorax Surgery; Thoraxkirurgi;

   Abstract : Implantation of a left ventricular assist device (LVAD) is a potential treatment in terminal heart failure. Right ventricular (RV) failure is a severe complication in these patients and sometimes requires additional placement of a right ventricular assist device (RVAD). READ MORE

6. 4. Cardioplegia and cardiac function : evaluated by left ventricular pressure-volume relations

   Author : Anders B Ericsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : cardioplegia; simultaneous cardioplegia; intermittent warn cardioplegia; cardiac function; pressure-volume loops; conductance catheter; heart rate;

   Abstract : Purpose: This thesis is focused on studies of blood cardioplegia in order to evaluate regimens of myocardial protection during cardiac surgery. To further bring down operative mortality and morbidity, in patients with acutely ischaemic hearts, an optimal peroperative myocardial management is essential. READ MORE

7. 5. Left ventricular filling during coronary artery bypass grafting

   Author : Sten Samuelsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Heart: surgery; coronary artery revascularization; ventricle; mitral valve Cardiopulmonary bypass Cardiac output Thermodilution Echocardiography: transesophageal; two-dimensional; Doppler Radionuclide ventriculographySten Samue;

   Abstract : Left ventricular (LV) filling, determination of preload, right ventricular end-diastolic volumes, volume contributions during early (E) and atrial (A) phases of LV filling and mitral valve opening areas were studied in 75 patients scheduled for elective coronary artery bypass grafting (CABG). The purposes of the study were: (1) To evaluate changes in LV filling judged as peak velocity E/A ratios determined by Doppler transesophageal echocardiography during and in the early phase after CABG.
