Figulla PFO occluder versus Amplatzer PFO occluder for percutaneous closure of patent foramen ovale

Percutaneous closure of patent foramen ovale (PFO) has been shown safe and feasible using several devices. The Occlutech Figulla single layer PFO Occluder (FPO) constitutes an alternative to the Amplatzer PFO Occluder (APFO).

Impact of percutaneous patent foramen ovale closure on migraine course

Migraine is a neurological disorder characterized by an increased individual susceptibility to respond to certain triggers by a propagating wave of neuronal depolarization that culminates in typical migraine headaches. Patients with a patent foramen ovale or any kind of right-to-left shunt are more likely to have migraine; and patients with migraine with aura are more likely to have a patent foramen ovale than patients without migraine. Nonrandomized reports of patent foramen ovale closure in divers, in patients with paradoxical embolism and in migraine patients with ischemic brain lesions have shown an impressive reduction in migraine headaches during follow-up. To date, the only double-blind, randomized controlled trial with a sham procedure in the control arm failed to show any benefit, probably owing to inadequate patient selection and maybe because of a high residual shunt rate. Two other randomized trials continue to enroll patients with migraine with aura and drug-refractory headaches and their results are awaited.

Rapid closure technique in decompressive craniectomy

The object of this study was to describe the rapid closure technique in decompressive craniectomy without duraplasty and its use in a large cohort of consecutive patients.

Randomized clinical trial comparing percutaneous closure of patent foramen ovale (PFO) using the Amplatzer PFO Occluder with medical treatment in patients with cryptogenic embolism (PC-Trial): rationale and design

Background Several studies have shown an association of cryptogenic stroke and embolism with patent foramen ovale (PFO), but the question how to prevent further events in such patients is unresolved. Options include antithrombotic treatment with warfarin or antiplatelet agents or surgical or endovascular closure of the PFO. The PC-Trial was set up to compare endovascular closure and best medical treatment for prevention of recurrent events. Methods The PC-Trial is a randomized clinical trial comparing the efficacy of percutaneous closure of the PFO using the Amplatzer PFO occluder with best medical treatment in patients with cryptogenic embolism, i.e. mostly cryptogenic stroke. Warfarin for 6 months followed by antiplatelet agents is recommended as medical treatment. Randomization is stratified according to patients age (<45 versus ≥45 years), presence of atrial septal aneurysm (ASA yes or no) and number of embolic events before randomization (one versus more than one event). Primary endpoints are death, nonfatal stroke and peripheral embolism. Discussion patients were randomized in 29 centers of Europe, Canada, and Australia. Randomization started February 2000. Enrollment of 414 patients was completed in February 2009. All patients will be followed-up longitudinally. Follow-up is maintained until the last enrolled patient is beyond 2.5 years of follow-up (expected in 2011).

Left atrial appendage closure with amplatzer cardiac plug in atrial fibrillation: initial European experience

In most patients with atrial fibrillation (AF) and stroke, there is thrombotic embolization from the left atrial appendage (LAA). Percutaneous closure of the LAA is a novel alternative for the treatment of patients with AF at a high risk of stroke, in whom long-term anticoagulation therapy is not possible or not desired. This study details the initial experience with the Amplatzer Cardiac Plug (ACP) in humans.

Surgery for complications of trans-catheter closure of atrial septal defects: a multi-institutional study from the European Congenital Heart Surgeons Association

This study aims to analyse the collective experience of participating European Congenital Heart Surgeons Association centres in the surgical management of complications resulting from trans-catheter closure of atrial septal defects (ASDs).
