Brief Summary:
The purpose of this study is to compare two treatments strategies to prevent further attacks in patients who have suffered an stroke or occlusion of a major artery with no obvious reason other than a persistent small opening between the upper heart chambers
Detailed Description:
In patients who have suffered a stroke or occlusion of a large artery in another body part of unknown origin a possible cause is a small opening between the upper heart chambers (patent foramen ovale, it is called). After birth this opening closes in 75% of the population, while it persists in 25% of people. It may allow a small blood clot to pass from the veins of the legs through the heart into the brain or other parts of the body. In order to reduce the risk for a further attack we have today more therapeutic options to choose from but it is unclear which strategy have the best outcome. This study is created to compare the effect of two treatment strategies:
1. Medical treatment The purpose of medical treatment is to dilute the blood to a degree, that no thrombus formation occurs. Since the opening in the heart persists, treatment is usually recommended lifelong. And patients treated with coumadin must undergo regular blood tests to ensure an adequate effect of the drug.
2. Catheter closure of patent foramen ovale An alternative method developed to close the small opening in the heart utilizes catheters which are introduced in a blood vessel in the groin and from there advanced to the heart. An umbrella device is then delivered through the catheter, positioned within the small defect and released. The umbrella is overgrown with own tissue within weeks to months and closes the small defect for ever.
