RESUMEN
Background: Patent foramen ovale (PFO) is seen in 25% of the general population but in up to 50% of patients ≤60 years old with cryptogenic strokes. Trials have shown that PFO closure vs medical therapy reduces the risk of future strokes. PFO closure may cause atrial fibrillation (AF), with prior trials reporting an incidence of 2% to 11.9%. However, the true incidence of AF after PFO closure is unknown due to limitations in prior studies for long-term monitoring. Methods: This is a retrospective observational study at a single center. Patients who underwent PFO closure and had an implantable loop recorder prior to PFO closure were included. The final review included 38 patients who had at least 2 months of implantable loop recorder data post-PFO closure. Results: Ten out of 38 (26%) patients developed AF post-PFO closure. The median time to the first episode of AF was 3.95 weeks, with 40% having their first AF episode after 3 months. Median duration of AF episodes was 1 hour. One hundred percent had spontaneous termination of AF. Of the AF patients, 70% were started on oral anticoagulant therapy. Conclusions: Our review shows a higher incidence of AF post-PFO closure as compared with most reported prior studies. We recommend larger prospective studies to explore the true incidence of AF post-PFO closure, its clinical impact, and subsequent stroke risk.
RESUMEN
OBJECTIVES: In the trans-radial era, arm venous access for right heart catheterization (RHC) is rising. Procedural success is affected by many factors, including subclavian/innominate vein stenosis (SVS) and pre-existing wires or catheters. In a study published previously by the same authors, 2% of cases had unsuccessful RHC through the arm, predominantly due to SVS. Since that study, techniques to improve RHC success rates have been developed, including crossing the stenosis with a coronary guidewire, followed by balloon dilatation. We aimed to determine whether subclavian/innominate venoplasty allows successful RHC in patients with SVS. METHODS: Our retrospective study included patients who had RHC from the arm between November 1, 2019, and December 31, 2022 that was unsuccessful due to the inability to pass a catheter through the SVS, and then underwent balloon venoplasty. The success rate of completed RHC was then assessed. RESULTS: Out of 2506 RHCs via arm access, 2488 were successful with a catheter alone or over a guidewire. In 18 patients, venoplasty was needed for catheter passage over a guidewire. Post-dilatation, all 18 cases (100%) had successful RHC with a mean procedural time of 35.2 (SD = 15.5) minutes. The most common stenosis site was the subclavian vein in 13 patients (72.2%), and 12 patients (66.7%) had pacemaker/ implantable cardioverter defibrillator wires present. CONCLUSIONS: Balloon dilatation of SVS is an efficacious method to improve the success rate of RHC from the arm. It is a safe technique that may prevent cross-over to a different access site, thereby improving patient satisfaction and reducing the possibility of alternate site complications.
RESUMEN
BACKGROUND: Acupuncture of the governor vessel and Yangming meridian are widely used in the treatment of acute ischemic stroke (AIS). However, the optimal meridian for acupuncture in the treatment of AIS remains uncertain. PURPOSE: This network meta-analysis study aimed to compare the clinical effectiveness of acupuncture at governor vessel and Yangming meridian in the treatment of AIS. METHODS: All relevant studies published in CNKI, WANFANG, VIP, Sinomed, Cochrane Library, Web of Science, Pub Med, and Embase before January 13, 2024 were systematically retrieved. The two researchers independently screened the studies and extracted the data. Cochrane ROB tool was used to evaluate the quality of the studies, and Stata 14.0 software was used to conduct a network meta-analysis of neurological deficit score, activities of daily living (ADL), clinical effective rate and Fugl-meyer motor function evaluation (FMA). RESULTS: A total of 401 studies were obtained, and 17 studies met the inclusion criteria. The surface under the cumulative ranking curve (SUCRA) values of the four outcome indexes were all ranked by "Governor vessel acupuncture + Conventional neurology treatment(GVAc+CT) > Yangming meridian acupuncture + Conventional neurology treatment(YMAc+CT) > Conventional neurology treatment (CT)". Compared to YMAc+CT and CT, GVAc+CT had the best effect in reducing the degree of neurological deficit score (SMD = -0.72, 95%CI = [-1.22,-0.21] and SMD = -1.07,95%CI = [-1.45,-0.69], respectively) and promoting the recovery of ADL((SMD = 0.59,95%CI = [0.31,0.88] and SMD = 0.96,95%CI = [0.70,1.21], respectively). Compared to CT, GVAc+CT also had a better clinical effective rate in the treatment of AIS (RR = 1.14,95%CI = [1.04,1.25]). CONCLUSIONS: Governor vessel acupuncture combined with conventional neurology treatment has the best effect in reducing the degree of neurological deficit score and promoting the recovery of ADL in AIS patientscompared to YMAc+CT and CT. Governor Vessel acupuncture is the most preferable acupoint scheme for clinical acupuncture treatment of AIS.
