1. 1. Mitral annulus motion in left ventricular pumping

   Författare :Kent Emilsson; Peter Carlens; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; Cardiology; Kardiologi;

   Sammanfattning : This thesis focus on the role of the mitral annulus motion (MAM) versus outer contour changes in the short axis, in left ventricular (LV) pumping. The influence of atrial contraction on LV dimensions and volumes and the relation between MAM and ejection fraction (EF) in sinus rhythm and in atrial fibrillation was also studied. LÄS MER

3. 2. Echocardiographic measurements at Takotsubo cardiomyopathy : transient left ventricular dysfunction

   Författare :Micael Waldenborg; Kent Emilsson; Ole Fröbert; Per Lindqvist; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Echocardiography; takotsubo; annulus motion; cardiac autonomic function; broken heart; diastolic; ventricular mass; concentric wall motion; Medicine; Medicin; Biomedicin; Biomedicine;

   Sammanfattning : Takotsubo cardiomyopathy (TTC) is a disease characterized by transient left ventricular (LV) dysfunction and typical wall motion abnormalities in apical parts, without obvious signs of coronary influence. Due to its elusive natural cause and the lack of clarified pathology, further studies are needed. LÄS MER

4. 3. Transoesophageal and transthoracic recordings of mitral annulus motion

   Författare :Bo Nilsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Left ventricular function; echocardiography; M-mode; tissue Doppler; mitral annulus systolic and diastolic velocities;

   Sammanfattning : Maximal systolic and diastolic velocities recorded from four sites of the mitral annulus motion (MAM) reflect left ventricular (LV) performance. This thesis focus on factors influencing M-mode derived velocities in healthy children and adults and reference values are proposed. LÄS MER

5. 4. Left Ventricular Systolic Dysfunction in 75-year-old Men and Women : A Community-based Study of Prevalence, Screening and Mitral Annulus Motion for Diagnosis and Prognostics

   Författare :Pär Hedberg; Tommy Jonason; Ivar Ringqvist; Eva Nylander; Uppsala universitet; []
   Nyckelord :Medical sciences; Aged; Heart Failure; Ventricular Function; Prevalence; Echocardiography; Electrocardiography; Natriuretic Peptide; Mortality; MEDICIN OCH VÅRD; MEDICINE; MEDICIN;

   Sammanfattning : Reduced performance of the left ventricle to eject blood – left ventricular systolic dysfunction (LVSD) – is a common predecessor of the heart failure syndrome. With or without symptoms, LVSD is associated with a poor prognosis. LÄS MER

7. 5. Effect of valve replacement for aortic stenosis on ventricular function

   Författare :Ying Zhao; Michael Henein; Per Lindqvist; Eugenio Picano; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
