Persistent foramen ovale (PFO) is a congenital heart disease which represents 80% of atrial septal defects. It is a remnant of fetal circulation that functions in postnatal conditions as a transient interatrial right‑to‑‑left shunt of variable magnitude. Persistent foramen ovale may be implicated in the pathogenesis of several medical conditions, such as cryptogenic stroke, cryptogenic left circulation thromboembolism, migraine syndromes, and decompression sickness. The most frequent indication for PFO closure remains PFO‑associated left circulation thromboembolism. In select patients, PFO closure reduces stroke recurrence in comparison with medical therapy after more than 3 years of follow‑up on average, especially in patients with a high risk of recurrence. While in PFO‑associated left circulation embolism, there is now conclusive evidence on the growing benefit of PFO closure in long‑term follow‑up, in many other clinical conditions, the degree of certainty of the results is deceiving. In this paper, we will review the benefits and risks that one can expect in the long term after percutaneous PFO closure in various clinical scenarios in order to facilitate therapeutic decision making.

Aim: An underlying atrial vulnerability or a preexisting misdiagnosed atrial fibrillation in some patients who are candidates for patent foramen ovale (PFO) closure may lead to an unnecessary percutaneous intervention. The aim of this work was to define paroxysmal atrial fibrillation rate, through a 6-month insertable loop-recorder monitoring, in patients over 55 years old with cryptogenic stroke and PFO., Methods: PFO closure criteria: significant right-to-left shunt and at least one high-risk feature (permanent right-to-left shunt, atrial septal aneurysm, prominent Eustachian valve, recurrent brain ischemia, previous deep vein thrombosis, thrombophilia). Insertable cardiac monitoring criteria: previous cryptogenic stroke, more than 55 years and at least one atrial fibrillation risk factor (heart failure, hypertension, age older than 65 years, diabetes, atrial runs, left atrium dilatation, left ventricle hypertrophy, pulmonary disease, thyroid disease, obesity). Atrial fibrillation detection threshold: arrhythmia duration longer than 5 min., Results: From January 2008 to March 2017, 195 patients underwent to loop-recorder monitoring. A total of 70 (36%) patients were candidates for PFO closure. The 6-month silent atrial fibrillation rate was 11.4%. In the arrhythmia-free cohort, 28 patients (45.2%) underwent percutaneous foramen ovale closure (group A) and 34 (54.8%) were medically treated (group B). Atrial fibrillation detection rate was 14.3% in group A and 0% in group B. The 36-month atrial fibrillation-free survival was 76%., Conclusion: An occult preexisting atrial fibrillation may lead to unnecessary percutaneous foramen ovale closure in a significant proportion of patients. A 6-month loop-recorder monitoring may improve the patient oriented decision-making.

Purpose: The purpose of this research was to assess whether short-term psychotherapy enhances long-term clinical outcomes in patients with a recent acute myocardial infarction (AMI)., Methods: Patients ≤70 years old were randomized within 1 week of their AMI to short-term ontopsychological psychotherapy plus routine medical therapy vs routine medical therapy only. The primary composite outcome was defined as the combined incidence of new cardiovascular events (re-infarction, death, stroke, revascularization, life-threatening ventricular arrhythmias, and the recurrence of clinically significant angina) and clinically significant new comorbidities. Secondary outcome measures were: rates for individual components of the primary composite outcome; the rate of re-hospitalization for cardiovascular problems; and New York Heart Association functional class., Results: Ninety-four patients were analyzed, translating into 425 patient-years. The 2 treatment groups were similar across baseline characteristics. At 5-year follow-up, psychotherapy patients had a lower incidence of primary outcome, relative to controls (77/223 vs 98/202 patient-years, respectively; P = .035; absolute risk reduction = 19%, number needed to treat = 8); this benefit was attributable to the lower incidence of new comorbidities and clinically significant angina in the psychotherapy group. Gains in the primary outcome, relative to controls, among psychotherapy patients occurred in the first year and subsequently remained stable over the following 4 years., Conclusions: Adding short-term ontopsychological psychotherapy to routine secondary prevention of myocardial infarction improves clinical outcomes overall up to 5 years post AMI. Studying time trends may aid in better targeting of psychological interventions during follow-up. Larger studies remain necessary to confirm these results., Trial Registration: www.ClinicalTrial.gov NCT00769366., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Patent foramen ovale (PFO) is associated with a number of clinical syndromes in which it plays variable roles that, often, cannot be accurately determined. This situation creates conflicting data and controversial studies. However, in 2017 and 2018, four randomized clinical trials have been published, allowing for the clarification of certain issues pertaining to cryptogenic stroke. Shortly after this, 8 European scientific societies collaborated to publish the first official international position paper on PFO and cryptogenic stroke, based upon best-available evidence. In the current report, the main positions are presented, relating to PFO diagnosis, general management, and therapeutic choices. Generally speaking, given the complexity of PFO roles, an interdisciplinary and personalized approach was chosen, especially taking into consideration patient involvement at all stages of management. This approach is not suitably addressed by standard guidelines, but can be accommodated in a position statement like this. For this reason, it was possible to offer an approach capable of aiding clinicians to make rational, patient-shared decisions, even when the available evidence is either weak or scarce.

Atrial fibrillation (AF) is the most common arrhythmia and its prevalence is increasing due to the progressive aging of the population. About 20% of strokes are attributable to AF and AF patients are at 5-fold increased risk of stroke. The mainstay of treatment of AF is the prevention of thromboembolic complications with oral anticoagulation therapy. Drug treatment for many years has been based on the use of vitamin K antagonists, but recently newer and safer molecules have been introduced (dabigatran etexilate, rivaroxaban, apixaban and edoxaban). Despite these advances, many patients still do not receive adequate anticoagulation therapy because of contraindications (relative and absolute) to this treatment. Over the last decade, percutaneous closure of left atrial appendage, main site of thrombus formation during AF, proved effective in reducing thromboembolic complications, thus offering a valid medical treatment especially in patients at increased bleeding risk. The aim of this consensus document is to review the main aspects of left atrial appendage occlusion (selection and multidisciplinary assessment of patients, currently available methods and devices, requirements for centers and operators, associated therapies and follow-up modalities) having as a ground the significant evolution of techniques and the available relevant clinical data.

There is no generally accepted consensus on the management of patent foramen ovale (PFO) in the presence of cryptogenic cerebral ischemia, because of the lack of conclusive evidence. The aim of this position paper was to develop and promote a joint approach based on available data that may be shared by different specialists, while waiting for definite results from randomized controlled trials. A position statement was produced involving the major national scientific societies. The task force members were nominated by the presidents and/or executive boards of each society or working group, as appropriate, based on their previous work in relevant topic areas. Specific task force working groups prepared the drafts. In order to achieve maximum agreement, these drafts were merged and distributed to the scientific societies for local evaluation. The ensuing final draft, merging all the revisions, was reviewed by the task force and finally approved by all scientific societies. The following issues were addressed: definitions of transient ischemic attack (TIA) and both symptomatic and asymptomatic cryptogenic stroke; formulation of a diagnostic workup for patients with clinical event(s) and PFO; recommendations regarding medical and interventional treatment options considering individual risk factors based on the three available randomized trials and other observational studies; recommendations regarding requirements for operators and centers in Italy; definition of a follow-up evaluation protocol. In conclusion, available data provided the basis for the first multi-society position paper on the management of cryptogenic stroke/TIA and PFO.
