Pfo Closure

Background and Objectives: According to guidelines, patent foramen ovale (PFO) closure is recommended for secondary stroke prevention in patients with cryptogenic stroke. Paradoxial embolism from PFO-mediated right to left shunt has been described as the mechanism of stroke in these cases. The aim of the study was to determine whether PFO closure can be associated with improvement of complaints (headaches, fatigue, heart palpitations, dizziness, and visual impairment) and determine its long-term effectiveness on recurrent stroke risk reduction. Materials and Methods: A total of 103 patients were enrolled in a retrospective study and followed-up by phone up to five years after PFO closure. Standardized survey was conducted about their well-being, recurrent cerebrovascular events, and the use of prescribed medication. Patients were also followed up for residual shunts 24 h, 30 days, 1 year, and 2 years after PFO. The pathogenic ischemic stroke subtypes are determined using CCS (Causative Classification System for Ischemic Stroke). Results: Male patients accounted for 43.7% (n = 45). The mean age was—44.4 ± 13 (18–75). The most probable cause for cryptogenic stroke for 53.4% (n = 55) of patients with possible cardio-aortic embolism was PFO. Residual shunts were mostly observed in patients with Amplatzer occluder—87.5% (n = 14). There was correlation between residual shunt and increased risk of transient ischemic attack recurrence (p = 0.067). Five-years after PFO closure recurrent cerebrovascular events were reported in only 5.1% (n = 5) of patients, this difference is statistically relevant (p < 0.001). Out of 51 patients presented with complaints before PFO closure, 25.5% (n = 13) did not present with any complaints after PFO closure. Conclusions: PFO can be considered a possible risk factor for cryptogenic stroke. PFO closure is effective in reducing recurrent cerebrovascular events. Residual shunt after PFO closure increases the risk of transient ischemic attack recurrence. Amplatzer occluder device is associated with a higher risk for residual shunts after PFO closure. PFO closure can be associated with improvement of complaints.

Pfo Closure

Percutaneous closure of patent foramen ovale (PFO) is widely performed to prevent recurrent stroke or transient ischemic attack in patients with cryptogenic stroke. However, the influence of different degrees of right-to-left shunting (RLS) has rarely been reported. We retrospectively evaluated the cases of 268 patients with cryptogenic stroke who underwent PFO closure at our hospital from April 2012 through April 2015. In accordance with RLS severity, we divided the patients into 2 groups: persistent RLS during normal breathing and the Valsalva maneuver (n=112) and RLS only during the Valsalva maneuver (n=156). Baseline characteristics, morphologic features, and procedural and follow-up data were reviewed. The primary endpoint was stroke or transient ischemic attack. More patients in the persistent group had multiple or bilateral ischemic lesions, as well as a larger median PFO diameter (2.5 mm [range, 1.8–3.9 mm]) than did patients in the Valsalva maneuver group (1.3 mm [range, 0.9–1.9 mm]) (P &lt;0.001). Atrial septal aneurysm was more frequent in the persistent group: 25 patients (22.3%) compared with 18 (11.5%) (P=0.018). Three patients in the persistent group had residual shunting. The annual risk of recurrent ischemic stroke was similar between groups: 0.298% (persistent) and 0.214% (Valsalva maneuver). Our findings suggest that patients with persistent RLS have more numerous severe ischemic lesions, larger PFOs, and a higher incidence of atrial septal aneurysm than do those without. Although our persistent group had a greater risk of residual shunting after PFO closure, recurrence of ischemic events did not differ significantly from that in the Valsalva maneuver group.

Background: The optimal strategy of secondary stroke prevention in patients with patent foramen ovale (PFO) is controversial. This study was performed to evaluate the efficacy and safety of the device closure (DC) versus the medical therapy (MT) in patients with cryptogenic stroke or transient ischemic attack (TIA) and PFO. Summary: Randomized controlled trials with active and control groups receiving the DC plus MT and MT alone in patients with history of cryptogenic stroke/TIA and diagnosis of PFO were systematically searched. The main efficacy outcome was stroke recurrence. Subgroup-analyses were performed according to age, shunt size, and presence of atrial septal aneurysm (ASA). Safety endpoints included any serious adverse event (SAE), atrial fibrillation (AF), and major bleeding complications. Risk ratios (RRs) and hazard ratios (HRs) with 95% CIs were estimated. Five trials were included, involving 3,440 participants (DC = 1,829, MT = 1,611). There was a protective effect of closure in the risk of recurrent stroke (RR 0.43 [0.21–0.90]; p = 0.024; HR = 0.39 [0.19–0.83]; p = 0.014). The benefit of PFO closure was significant in patients with PFO associated with substantial right-to-left shunt or ASA. There were no differences in the risks of SAEs and major bleedings between the groups. The rate of new-onset AF was higher in the DC than in the MT arm (RR 4.46 [2.35–8.41]; p < 0.001). Successful device implantation and effective PFO closure were achieved in 96 and 91% of the patients respectively. Key Messages: In selected adult patients with PFO and history of cryptogenic stroke, the DC plus MT is more effective to prevent stroke recurrence and is associated with an increased risk of new-onset AF compared to the MT alone.
