Background: The Cocoon patent foramen ovale (PFO) Occluder is a new generation nitinol alloy double-disk device coated with nanoplatinum, likely useful in patients with nickel hypersensitivity. Early results and mid-term outcomes of this device in percutaneous PFO closure are missing.
Aims: To assess the preliminary efficacy and safety profile of PFO closure with Cocoon device in an Italian multi-center registry.
Methods: This is a prospective registry of 189 consecutive adult patients treated with the Cocoon PFO Occluder at 15 Italian centers from May 2017 till May 2020. Patients were followed up for 2 years.
Results: Closure of the PFO with Cocoon Occluder was carried out successfully in all patients, with complete closure without residual shunt in 94.7% of the patients and minimal shunt in 5.3%. Except from a case of paroxysmal supraventricular tachycardia and a major vascular bleeding, no procedural and in-hospital device-related complications occurred. No patient developed cardiac erosions, allergic reactions to nickel, or any other major complications during the follow-up. During the follow-up period, 2 cases of new-onset atrial fibrillation occurred within thirty-day.
Conclusions: Percutaneous closure of PFO with Cocoon Occluder provided satisfactory procedural and mid-term clinical follow-up results in a real-world registry.

Patent foramen ovale (PFO) closure using percutaneous devices, such as the Amplatzer occluder, is a common treatment for patients with a history of cryptogenic stroke or transient ischemic attack (TIA). Although generally well-tolerated, some patients may develop adverse reactions to the device materials, particularly in the presence of a nickel allergy. Symptoms can include chest pain, rashes, and migraines, which may necessitate surgical removal of the device.

Patent foramen ovale (PFO) is a congenital heart defect affecting up to 25% of the population, associated with an increased risk of cryptogenic stroke. Percutaneous PFO closure is a minimally invasive procedure aimed at reducing stroke risk by eliminating the right-to-left shunt. This monocentric, retrospective study analyzed 716 patients who underwent PFO closure between January 2000 and February 2023.

Unmasking the Rarity: A Case Report on Platypnea-Orthodeoxia Syndrome With Successful Resolution Through Patent Foramen Ovale Closure.
J Med Cases

Department of Cardiology, McLaren Flint Hospital, Flint, MI, USA.
Article Synopsis
- Platypnea-orthodeoxia syndrome (POS) is a rare condition where a person experiences breathlessness and low oxygen levels when standing, but feels better when sitting or lying down, contrasting with orthopnea which worsens when lying flat.
- A case study highlighted a 79-year-old woman with various health issues, including chronic kidney disease and a history of pulmonary embolism, who was found to have a severe patent foramen ovale (PFO) that likely contributed to her POS symptoms.
- After successfully closing the PFO with a medical device, the patient showed significant improvement and was discharged within two days, emphasizing the importance of recognizing and treating POS to prevent serious health risks.
Transcatheter Closure of a Patent Foramen Ovale With a Small Adjacent Atrial Septal Defect and a Double Interatrial Septum Post Cryptogenic Stroke.

The phenomenon of double interatrial septum (DIAS) represents a particularly rare subtype of atrial septal malformation, characterized by the presence of dual membranes separating the atria, resulting in a distinctive interatrial space. This unique anatomical structure has been linked to a paradoxical right-to-left shunt, potentially contributing to embolic ischemic strokes. Within this context, we report a rare case of a 34-year-old female who presented with a transient ischemic attack (TIA) and was diagnosed with patent foramen ovale (PFO) and a small adjacent atrial septal defect (ASD), along with the presence of a DIAS.
