  1. 1. Diagnosis of interatrial shunts and the influence of patent foramen ovale on oxygen desaturation in obstructive sleep apnea

    Författare :Magnus C Johansson; Göteborgs universitet; []
    Nyckelord :Patent foramen ovale; atrial septal defect; obstructive sleep apnea; contrast transesophageal echocardiography; percutaneous closure;

    Sammanfattning : Patent foramen ovale (PFO) is found in 27% of the population and although mostly asymptomatic, PFO has been associated with e.g. cryptogenic stroke and, rarely, also with oxygen desaturation. PFO and atrial septal defects may nowadays be closed percutaneously without open heart surgery. LÄS MER

    Sammanfattning : Stroke is one of the main causes of death and disability worldwide, and only in Sweden approximately 25 000 individuals suffer from stroke each year. This thesis focuses on two common conditions; migraine and patent foramen ovale (PFO) and their role in stroke. LÄS MER

  4. 3. Prognosis and clinical outomes in stroke patients with transcatheter closure of an atrial shunt

    Författare :Alexia Karagianni; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial shunt; cryptogenic stroke; patent foramen ovale; transcatheter intervention; cerebrovascular event; residual shunting;

    Sammanfattning : Background: The percutaneous transcatheter closure of a patent foramen ovale (PFO) after a cryptogenic cerebrovascular event (CVE) has been performed for more than two decades. In contrast with previous randomized studies, recent randomized studies support the closure of the PFO after a cryptogenic CVE in preference to medical treatment alone. LÄS MER

  5. 4. The Role of Transesophageal Echocardiography in Clinical Decision-Making in Patients with Stroke or Atrial Fibrillation

    Författare :Anders Roijer; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; stroke; cardioversion; Transesophageal echocardiography; embolic sources; atrial fibrillation;

    Sammanfattning : The subject of this thesis is the clinical use of transesophageal echocardiography (TEE) in patients with stroke or atrial fibrillation. Subjects were examined with echocardiography and sonography of the carotid artery. A control group of randomly selected volunteers without cerebrovascular disease was compared to patients with ischemic stroke. LÄS MER
