متن کاملAbsence of recurrent stroke after percutaneous closure of patent foramen ovale despite residual right-to-left cardiac shunt assessed by transcranial Doppler.
BACKGROUND Percutaneous transcatheter closure of patent foramen ovale has been proposed to prevent recurrent strokes in young adults. Contrast transcranial Doppler ultrasonography provides a functional, semiquantitative evaluation of right-to-left cardiac shunt. AIMS To evaluate the efficacy of percutaneous closure of patent foramen ovale in suppressing right-to-left shunt (assessed using tra...
