1. Cerebrovascular accidents associated with aortic manipulation during cardiac surgery
Sammanfattning : Background: Despite the successful development in cardiac surgery, cerebrovascular accidents (CVA) remain a devastating complication. Aortic atherosclerosis has been identified as a major risk factor for CVA. LÄS MER
2. Evaluation of a Laser Doppler System for Myocardial Perfusion Monitoring
Sammanfattning : Coronary artery bypass graft (CABG) surgery is a common treatment for patients with coronary artery disease. A potential complication of CABG is myocardial ischemia or infarction. In this thesis, a method - based on laser Doppler flowmetry (LDF) - for detection of intra- and postoperative ischemia by myocardial perfusion monitoring is evaluated. LÄS MER
3. The use of mechanical circulatory support and passive ventricular constraint in patients with acute and chronic heart failure
Sammanfattning : Many patients are diagnosed as having chronic heart failure (CHF) and apart from the fact that daily activities are impaired, they are great consumers of health care, and the prognosis is poor. The distinction between acute heart failure (AHF) and CHF may be difficult and is more a question of time rather than severity. LÄS MER
4. Quantitative diffuse reflectance spectroscopy : myocardial oxygen transport from vessel to mitochondria
Sammanfattning : In the field of biomedical optics, diffuse reflectance spectroscopy (DRS) is a frequently used technique for obtaining information about the optical properties of the medium under investigation. The method utilizes spectral difference between incident and backscattered light intensity for quantifying the underlying absorption and scattering processes that affects the light-medium interaction.

5. Management of patients treated with left ventricular assist devices : A clinical and experimental study
Sammanfattning : This thesis describes the management of patients treated with mechanical circulatory support devices for short- or long-term use. Twenty-four patients suffering from postcardiotomy heart failure were treated with a minimally invasive axial flow pump. LÄS MER
