Why the study?
Is echocardiographically guided closure of a patent foramen ovale without fluoroscopy feasible in a pregnant woman with recurrent strokes?
Is echocardiographically guided closure of a patent foramen ovale without fluoroscopy feasible in a pregnant woman with recurrent strokes?
Echocardiographically guided PFO closure without fluoroscopy is feasible and can be considered in pregnant patients with recurrent paradoxical embolism to avoid radiation exposure.
Answers are grounded in this paper and cite their sources.
May support fluoroscopy-free PFO closure in pregnancy; hypothesis-generating and should not yet change practice.
BACKGROUND: Stroke during pregnancy and puerperium is a severe complication that causes high morbidity and mortality. A patent foramen ovale (PFO) allowing paradoxical embolism is one identified risk factor. CASE: A 25-year-old pregnant woman with PFO suffered from recurrent cerebral embolism. To prevent recurrent cerebral embolism during pregnancy, delivery, and puerperium, interventional closure of the PFO was performed without fluoroscopy under echocardiographic guidance. The postinterventional course was uneventful. CONCLUSION: Percutaneous transvenous closure of a PFO during pregnancy is feasible without the use of fluoroscopy.
