Prevalence of patent foramen ovale in subjects with obstructive sleep apnea: a transcranial Doppler ultrasound study
Background: Under particular conditions a patent foramen ovale (PFO) can potentially give rise to ischemic stroke by means of paradoxic embolization. In obstructive sleep apnea syndrome (OSAS) right to left shunting (RLSh) can occur through PFO during periods of nocturnal apnea. Our study aimed to e...

| description | Background: Under particular conditions a patent foramen ovale (PFO) can potentially give rise to ischemic stroke by means of paradoxic embolization. In obstructive sleep apnea syndrome (OSAS) right to left shunting (RLSh) can occur through PFO during periods of nocturnal apnea. Our study aimed to evaluate the prevalence of PFO diagnosed by means of transcranial Doppler (TcD) in subjects with OSAS.
Methods: Seventy-eight consecutive subjects with OSAS (mean age 53±12 years) and 89 normal controls (mean age 48±9 years) underwent TcD with intravenous application of agitated physiological saline solution. The test was performed on patients at rest and during Valsalva maneuver.
Results: PFO was present in 21 out of 78 patients with OSA (27%) and in 13 out of 89 control patients (15%). Seventeen out of 21 patients with OSA showed PFO only during Valsalva maneuver (85%) with respect to 12 out of 13 subjects of the control group (92%). Prevalence of PFO in OSAS was statistically different with respect to the control group (

Prevalence of PFO in OSAS was statistically different with respect to the control group (
P<0.05). However, no statistically significant differences could be found for the prevalence of provocative-only shunting PFO with respect to already at rest shunting PFO in patients with OSAS with respect to the control group.
Conclusions: Prevalence of PFO in subjects with OSA is significantly higher than in normal controls. The shunt is frequently present only during Valsalva maneuver.</description><identifier>ISSN: 1389-9457</identifier><identifier>EISSN: 1878-5506</identifier><identifier>DOI: 10.1016/S1389-9457(02)00256-3</identifier><identifier>PMID: 14592325</identifier><language>eng</language><publisher>Netherlands: Elsevier B.V</publisher><subject>Adult ; Aged ; Female ; Heart Septal Defects, Atrial - diagnostic imaging ; Heart Septal Defects, Atrial - epidemiology ; Humans ; Intracardiac shunting ; Male ; Middle Aged ; Obstructive sleep apnea ; Patent foramen ovale ; Prevalence ; Risk Factors ; Sensitivity and Specificity ; Sleep Apnea, Obstructive - diagnostic imaging ; Sleep Apnea, Obstructive - epidemiology ; Stroke - diagnostic imaging ; Stroke - epidemiology ; Transcranial Doppler ; Ultrasonography, Doppler, Transcranial ; Valsalva Maneuver</subject><ispartof>Sleep medicine, 2003-05, Vol.4 (3), p.219-223</ispartof><rights>2003 Elsevier Science B.V.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c413t-8e409924fec6f66d7d2d8e97f57a27857745cf2fe00a7dcc012020e4b0557f233</citedby><cites>FETCH-LOGICAL-c413t-8e409924fec6f66d7d2d8e97f57a27857745cf2fe00a7dcc012020e4b0557f233</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://www.sciencedirect.com/science/article/pii/S1389945702002563$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,776,780,3537,27901,27902,65534</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/14592325$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Beelke, Manolo</creatorcontrib><creatorcontrib>Angeli, Silvia</creatorcontrib><creatorcontrib>Del Sette, Massimo</creatorcontrib><creatorcontrib>Gandolfo, Carlo</creatorcontrib><creatorcontrib>Cabano, Maria Eloisa</creatorcontrib><creatorcontrib>Canovaro, Paola</creatorcontrib><creatorcontrib>Nobili, Lino</creatorcontrib><creatorcontrib>Ferrillo, Franco</creatorcontrib><title>Prevalence of patent foramen ovale in subjects with obstructive sleep apnea: a transcranial Doppler ultrasound study</title><title>Sleep medicine</title><addtitle>Sleep Med</addtitle><description>Background: Under particular conditions a patent foramen ovale (PFO) can potentially give rise to ischemic stroke by means of paradoxic embolization.
