2. 1. 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

4. 2. 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

5. 3. 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

6. 4. 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

7. 5. 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
