[Transcatheter closure of patent foramen ovale in patients after cryptogenic stroke].
Paradoxical embolism through a patent foramen (PFO) is a possible mechanism of ischaemic stroke in patients with cryptogenic stroke. Occlusion of PFO in such patients is considered by some authors as most effective in stroke prevention. We present our initial experience with transcatheter closure of PFO with the new self-expanding device--the Amplatzer PFO occluder in three young patients (age < 50 years). Each of them experienced at least one ischaemic stroke episode, without a left heart or carotid source and each had an interatrial communication with right-to-left shunting during Valsalva manoeuvre on echocardiography. The PFO's were closed completely without complications, under transoesophageal echo guidance in general anaesthesia. Complete closure was confirmed at one-month follow-up echocardiogram in each patient. No repeat cerebral accidents occurred at that time. The procedures were relatively easy and the clear presentation of the implant on TEE and fluoroscopy, made implantation fully controlled. The unique feature of the device is, that until release it can easily be retrieved, repositioned or removed. Transcatheter closure of PFO with the Amplatzer PFO occluder may become the new therapeutic option for patients with cryptogenic stroke and presumed paradoxical embolism.
