Study Details
Study Description
Brief Summary
The aim of this study is to evaluate the benefits of patent foramen ovale (PFO) closure on patients with obstructive sleep apnea (OSA) and persistent hypoxia despite optimal therapy.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Persistent hypoxemia after Obstructive sleep apnea group Participants will receive Patent Foramen Ovale (PFO) closure and followed until repeat sleep apnea testing up to 6 months. |
Procedure: PFO closure
The participants will receive a onetime closure of a small hole in heart. The procedure usually takes up to an hour. The procedure is done with local anesthesia and conscious sedation. A catheter is inserted into a vein in upper thigh and threaded to heart to deploy the closure device. Either Gore septal occluder or Amplatzer PFO occluder

Outcome Measures
Primary Outcome Measures
- changes in the apnea hypoxia index [baseline and then up to 3 months after the study]
The Apnea hypopnea index that ranges from: 0 to 5 is normal 5 to15 is mild 15 to 30 is moderate greater than 30 is severe.
- change in mean nocturnal oxygen saturation [baseline and then up to 3 months after the study]
Oxygen saturation will be measured in percentage. Ranges from 0 to 100 percent. The higher the percent the higher the oxygen saturation.
- change in duration of nocturnal oxygen desaturation duration. [baseline and then up to 3 months after the study]
Will be measured in seconds.
Secondary Outcome Measures
- change in quality of life as measured by the patient global impression of change scale. [baseline and then up to 3 months after the study]
Change Scale: Adapted Patient Clinical Global Impression of Improvement (CGI-I) scale rated by the patient is a 7-point scale of improvement from 'very much improved' to 'very much worse'. 'Very much improved' means a better outcome.
- change in quality of sleep as measured by the Epworth Sleepiness Scale [baseline and then up to 3 months after the study]
Epworth Sleepiness Scale: The Epworth Sleepiness Scale is widely used in the field of sleep medicine as a subjective measure of a patient's sleepiness. The test is a list of eight situations in which you rate your tendency to become sleepy on a scale of 0, no chance of dozing, to 3, high chance of dozing.
- Change in physical activity as measured by Godin Leisure time physical activity questionnaire. [baseline and then up to 3 months after the study]
Self-reported leisure time physical activity as assessed by the Godin Leisure time physical activity questionnaire in all participants. Score range from 0 upwards, with higher scores indicating more leisure time physical activity.
- change in fatigue as measured by the Fatigue Severity Scale. [baseline and then up to 3 months after the study]
Each item is scored between 1 and 7 (1 = strongly disagree, 7 = totally agree) in the scale consisting of 9 items that can be applied by individuals in a simple way. The total score range of the scale is 9-63. The total score is calculated by taking the average of 9 items. Accordingly, the lowest average score to be obtained is 1, and the highest average score is 7. The cut-off value was set at 4 and above to diagnose pathological fatigue. The lower the total score, the less fatigue.
- changes in functional independence measure [baseline and then up to 3 months after the study]
The Functional independence measure (FIM) is an 18-item instrument comprising 13 motor items and 5 cognitive items, with each item graded on a 7-point ordinal scale (1 denotes complete dependence and 7 denotes complete independence), including the ability to perform activities of daily living (ADLs) across 6 areas (self-care, sphincter control, transfers, locomotion, communication, and social cognition). Total admission FIM (Ta-FIM) scores, total discharge FIM (Td-FIM) scores (18 - 126), motor FIM (m-FIM) sub-scores (13 - 91) and cognitive FIM (c-FIM) sub-scores (5 - 35), were tabulated.
