  1. 1. Left atrial function in health and disease

    Författare :Mark Henein; Per Lindqvist; Stellan Mörner; Reidar Winter; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left atrium; Doppler echocardiography; atrial interaction; atrial pressure;

    Sammanfattning : The Objectives of this thesis are:1) To study possible atrial interaction in patients with right and left ventricular outflow tract obstruction due to significant pulmonary (PS) and aortic valve stenosis (AS), respectively.2) To assess left atrial (LA) intrinsic myocardial function and its relationship to indirect measures of left ventricular (LV) filling pressures in patients with paroxysmal atrial fibrillation (PAF).

  4. 3. Surgical Ablation of Atrial Fibrillation with Cryo and Radiofrequency Concomitant to Mitral Valve Surgery : Clinical, Biochemical and Echocardiography Outcomes

    Författare :Gabriella Boano; Farkas Vánky; Meriam Åström Aneq; Lena Jideus; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; Mitral valve surgery; Surgical ablation; Cox-Maze IV; Left atrium remodelling; 3D echocardiography;

    Sammanfattning : Atrial fibrillation (AF) is the most common arrhythmia seen in clinical practice. In cardiac surgery, the negative influence of AF on short- and long-term outcomes has made concomitant ablation procedures more common. LÄS MER

  5. 4. The clinical value of total isovolumic time

    Författare :Gani Bajraktari; Michael Henein; Krister Lindmark; Lars-Åke Brodin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; cardiac resynchronization therapy; predictors; echocardiography; total isovolumic time; six-minute walk test; left ventricular dyssynchrony;

    Sammanfattning : The objective of this thesis is to evaluate the use of Doppler echocardiography markers ofglobal dyssynchrony [total isovolumic time (t-IVT)] in the following 6 studies: 1) Its prognostic role in predicting cardiac events in patients undergoing CABG surgery,compared with conventional global systolic and diastolic measurements. 2) Its additional value in predicting six minute walk test (6-MWT) in patients with leftventricular (LV) ejection fraction (EF) .

  7. 5. No touch vein harvesting technique for coronary artery by-pass surgery : impact on patency rate, development of atheroscleosis, left ventricular function and clinical outcome during 16 years follow-up

    Författare :Benny Johansson; Eva Swahn; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atherosclerosis; coronary artery disease; coronary artery bypass grafting; vein grafts; no touch vein harvesting technique; intravascular ultrasound; echocardiography; clinical outcome; revascularization; outcome analysis; angina pectoris; myocardial infarction; mortality; randomized trial; Surgery; Kirurgi;

    Sammanfattning : This thesis was based on a prospective randomized trial which was started in 1993 to compare the no touch (NT) with the conventional (C) technique of saphenous vein harvesting for CABG.In paper I, was demonstrated superior patency for the NT grafts at short-term (1.5 years; 95,6% vs 89%; p < 0,05) and long-term follow-up (8.
