  2. 1. Survival and functional recovery following valve replacement in patients with severe aortic stenosis

    Author : Wenhong Ding; Michael Y Henein; Eugenio Picano; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; surgical aortic valve replacement; transcatheter aortic valve implantation; survival; predictor; echocardiography; speckle tracking; ventricular function; twist; strain; Cardiology; kardiologi;

    Abstract : Background: Aortic stenosis (AS) is the most common heart valve disease in Europe and North America. Age-related calcification of the valve is the commonest cause of acquired AS, especially in patients older than 70 years. READ MORE

  4. 2. Thoracic Aortic Surgery : Epidemiology, Outcomes, and Prevention of Cerebral Complications

    Author : Christian Olsson; Stefan Thelin; Jan van der Linden; Uppsala universitet; []
    Keywords : Surgery; Aorta; Thoracic; Aortic aneurysms; Aortic disease; Cardiovascular surgical procedures; Epidemiology; Registries; Treatment outcome; Survival analysis; Cerebral infarction; Near-infrared spectroscopy; Quality of life; Perfusion; Kirurgi;

    Abstract : The mortality of thoracic aortic diseases (mainly aneurysms and dissections) is high, even with surgical treatment. Epidemiology and long-term outcomes are incompletely investigated. Stroke is a major complication contributing to mortality, morbidity, and possibly to reduced quality of life. READ MORE

  5. 3. 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

  6. 4. Aortic valve surgery: Clinical studies after autograft, homograft and prosthetic valve replacement

    Author : Obaid Aljassim; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic valve surgery; Ross operation; Homograft; Doppler-Catheter gradients;

    Abstract : Aortic Valve Surgery Clinical studies after autograft, homograft and prosthetic valve replacement Obaid Aljassim, MD Department of Cardiovascular Surgery and Anaesthesia, Sahlgrenska University Hospital and University of Gothenburg Introduction and Aims: Aortic valve disease in symptomatic adult patients often requires surgery. Several alternatives are available: repair, mechanical and biological prostheses, homograft and the Ross procedure. READ MORE

  7. 5. Chlamydia pneumoniae in Aortic Valve Sclerosis and Thoracic Aortic Disease : Aspects of Pathogenesis and Therapy

    Author : Christina Nyström-Rosander; Kenneth Persson; Uppsala universitet; []
