  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. Outcome and risk factors after aortic valve interventions

    Author : Per Kvidal; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; aortic valve replacement; mechanical valve prosthesis; relative survival; morbidity; recurrent events; balloon aortic valvuloplasty; long-term follow-up; Kirurgi; Surgery; Kirurgi; kardiologi; Cardiology;

    Abstract : In the present study the long-term survival and morbidity and the associated risk factors after aortic valve replacement (AVR) and after aortic balloon valvuloplasty were evaluated. In a cohort of 2,359 consecutive patients undergoing primary aortic valve replacement, the early mortality was 5.6%. READ MORE

  5. 3. Prosthetic aortic heart valves

    Author : Natalie Glaser; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Aortic valve replacement (AVR) can be performed with different types of valve prostheses. There is no perfect aortic valve prosthesis, and the prosthetic choice for each patient requires careful consideration. This thesis evaluates mortality, morbidity, and prosthetic valve function after AVR with different aortic valve prostheses. READ MORE

  6. 4. Surgery for aortic stenosis : with special reference to myocardial metabolism, postoperative heart failure and long-term outcome

    Author : Farkas Vánky; Rolf Svedjeholm; Dan Lindblom; Linköpings universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Aortic stenosis; Surgery; Postoperative heart failure; Long-term outcome; Metabolism; Medicine; Medicin;

    Abstract : Postoperative heart failure (PHF) remains a major determinant of the outcome after cardiac surgery. However, characteristics of and risk factors for PHF after valve surgery have received little attention. READ MORE

  7. 5. Minimally invasive aortic valve replacement

    Author : Magnus Dalén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Minimally invasive aortic valve replacement (AVR) through a ministernotomy has been developed as an alternative approach to conventional full sternotomy AVR. During recent years, sutureless aortic bioprostheses were introduced with the aim to facilitate implantation, especially in minimally invasive procedures. READ MORE
