RESUMEN

PURPOSE OF REVIEW: Patent foramen ovale (PFO) has been previously linked to left circulation thromboembolism and stroke. This review article aims to discuss the latest evidence, updated societal guidelines, diagnostic algorithms and novel therapeutic devices for PFO closure. RECENT FINDINGS: PFO closure for cryptogenic stroke and systemic embolization is supported by a large body of evidence and has a strong societal recommendation. Limited data are available for platypnea-orthodeoxia syndrome, although closure appears to be beneficial. Current data do not support routine closure for migraines and decompression Illness. Development of heart-brain teams can improve identification of patients most likely to benefit from closure, utilizing a combination of imaging test and risk score algorithms. Multiple novel devices aiming at reducing complications and improving the long-term impact of current available devices are being evaluated. PFO closure has significantly progressed over the last years, with new data supporting its superiority in reducing risk of recurrent embolic stroke in patients with PFO-related stroke. Additional clinical data are required to provide further refinements on patient selection and guidance on treatment of specific subgroups.

RESUMEN

Background/Objectives: Myelin oligodendrocyte glycoprotein (MOG) is exclusively expressed in the central nervous system (CNS) and is found on the outer surface of oligodendrocytes. Antibodies to MOG are associated with CNS demyelination, whereas peripheral nervous system (PNS) demyelination is seldom reported to be related to MOG-IgG. Methods: The database of patients seen in our neurological academic center was searched for MOG-IgG seropositivity and concomitant demyelinating polyneuropathy. For the purpose of the review, in March 2024, we searched for case reports and case series in the following databases: PubMed, Scopus, Cochrane, and ScienceDirect. Inclusion criteria were MOG-IgG seropositivity and demyelinating polyneuropathy. Exclusion criteria were type of publication other than case reports and case series, unconfirmed diagnosis of demyelinating polyneuropathy, and other diseases causing demyelination in either the CNS or PNS. Critical appraisal of the selected case reports and case series was realized by JBI. Results: Four new cases were identified with MOG-IgG and confirmed demyelinating polyneuropathy. This review identified 22 cases that have been published since 2018. Clinical, imaging, neurophysiological, and immunological characteristics, as well as treatment options and outcomes are presented and compared to those of other cases with combined central and peripheral demyelination (CCPD). Conclusions: The pathogenetic mechanism is unclear; thus, different hypotheses are discussed. New case reporting and large cohort studies will help further the exploration of the underlying mechanism and guide more effective therapeutic interventions.

RESUMEN

BACKGROUND: Artificial intelligence (AI) is increasingly utilized in interventional cardiology (IC) and holds the potential to revolutionize the field. METHODS: We conducted a global, web-based, anonymous survey of IC fellows and attendings to assess the knowledge and perceptions of interventional cardiologists regarding AI use in IC. RESULTS: A total of 521 interventional cardiologists participated in the survey. The median age range of participants was 36 to 45 years, most (51.5%) practice in the United States, and 7.5% were women. Most (84.7%) could explain well or somehow knew what AI is about, and 63.7% were optimistic/very optimistic about AI in IC. However, 73.5% believed that physicians know too little about AI to use it on patients and most (46.1%) agreed that training will be necessary. Only 22.1% were currently implementing AI in their personal clinical practice, while 60.6% estimated implementation of AI in their practice during the next 5 years. Most agreed that AI will increase diagnostic efficiency, diagnostic accuracy, treatment selection, and healthcare expenditure, and decrease medical errors. The most tried AI-powered tools were image analysis (57.3%), ECG analysis (61.7%), and AI-powered algorithms (45.9%). Interventional cardiologists practicing in academic hospitals were more likely to have AI tools currently implemented in their clinical practice and to use them, women had a higher likelihood of expressing concerns regarding AI, and younger interventional cardiologists were more optimistic about AI integration in IC. CONCLUSIONS: Our survey suggests a positive attitude of interventional cardiologists regarding AI implementation in the field of IC.

RESUMEN

Introduction: Coffin-Siris syndrome (CSS) (MIM #135900) is an extremely rare genetic multisystemic disorder characterized by aplasia or hypoplasia of the upper phalanx of the fifth finger, moderate to severe cognitive and/or developmental delay, and characteristic facial features (thick lashes, hypertrichosis of the trunk, sparse hair). Congenital anomalies of the brain, kidney, and heart have been described but are less consistent across patients. Case presentation: We report a case of a 12-year-5-month-old girl with the clinical features of CSS, severe scoliosis, and epilepsy. Growth hormone deficiency was diagnosed at the age of 9 years. Recombinant human growth hormone (rhGH) treatment was started that resulted in a significant improvement of the growth velocity up to 5.4 cm/year (>90-97th centile). Next-generation sequencing identified a mutation in the ARID1B gene. Discusion: Despite its phenotypic heterogeneity, key features of CSS have become clearer and along with molecular diagnosis, a further global approach to improve the care of these individuals is enabled. Appropriate therapies for this population are needed to optimize growth and intellectual potentials.

RESUMEN

In the last 10 years, an increased number of patients presenting with acute encephalitis is being observed, a finding that is attributed to autoimmune mechanisms. Despite the fact that autoantibodies usually target the neuronal cell surface or synaptic proteins in the central nervous system (CNS), in many cases these remain undetectable, constituting a future diagnostic and therapeutic challenge. Human herpesvirus-7 (HHV-7) is proven to be a neurotropic virus, causing various neurological complications mostly in the adult population. We present the case of a 10-year-old girl, with confirmed active HHV-7 infection of the CNS, who developed acute seronegative autoimmune encephalitis. To our best knowledge, there is no literature concerning pediatric cases of autoimmune encephalitis following HHV-7 infection.

RESUMEN

Snyder-Robinson syndrome (SRS) is an extremely rare X-linked intellectual disability syndrome (MRXSSR; MIM #309583). The main clinical features of SRS include psychomotor delay, hypotonia, and asthenic-type body habitus - reduced body weight and bone abnormalities (osteoporosis, fractures, kyphoscoliosis). We report a case of SRS with a hemizygous missense variant in the SMS gene,c.334C>G (p.Pro112Ala), in a 4-year-old boy, who initially developed hypotonia, delayed motor skills, and subsequently epilepsy. This variant in SMS was found to be de novo. To the best of our knowledge, this novel SMS gene variant has never been previously reported in disease-related variation databases, such as ClinVar or HGMD.

RESUMEN

BACKGROUND: Promising genetic treatments targeting the molecular defect of severe early-onset genetic conditions are expected to dramatically improve patients' quality of life and disease epidemiology. Spinal Muscular Atrophy (SMA), is one of these conditions and approved therapeutic approaches have recently become available to patients. OBJECTIVE: Analysis of genetic and clinical data from SMA patients referred to the single public-sector provider of genetic services for the disease throughout Greece followed by a retrospective assessment in the context of epidemiology and genotype-phenotype associations. METHODS: Molecular genetic analysis and retrospective evaluation of findings for 361 patients tested positive for SMA- and 862 apparently healthy subjects from the general population. Spearman rank test and generalized linear models were applied to evaluate secondary modifying factors with respect to their impact on clinical severity and age of onset. RESULTS: Causative variations- including 5 novel variants- were detected indicating a minimal incidence of about 1/12,000, and a prevalence of at least 1.5/100,000. For prognosis a minimal model pertaining disease onset before 18 months was proposed to include copy numbers of NAIP (OR = 9.9;95% CI, 4.7 to 21) and SMN2 (OR = 6.2;95% CI, 2.5-15.2) genes as well as gender (OR = 2.2;95% CI, 1.04 to 4.6). CONCLUSIONS: This long-term survey shares valuable information on the current status and practices for SMA diagnosis on a population basis and provides an important reference point for the future assessment of strategic advances towards disease prevention and health care planning.

RESUMEN

PURPOSE OF REVIEW: Coronary artery disease remains the most common cause of death worldwide. In patients with biomarker-positive acute coronary syndrome, the combination of guideline-directed medical therapy with routine revascularization is associated with improved outcomes. However, the role of routine revascularization in stable ischemic heart disease, in addition to medical therapy, remains a matter of debate. In this review, we aimed to describe the role of revascularization in stable ischemic heart disease. RECENT FINDINGS: Revascularization is indicated in patients with stable ischemic heart disease and progressive or refractory symptoms, despite medical management. When guided by ischemia presence, revascularization has failed to show survival benefit, compared with medical therapy alone in multiple clinical trials. On the other hand, revascularization guided by coronary lesion severity, assessed by FFR or iFR, has been shown to offer survival benefit and improvement in symptom severity. PCI-revascularization of unprotected left main disease is feasible with comparable to surgical approach outcomes. Clinical decision to perform revascularization in stable ischemic heart disease necessitates a heart team approach, and no simple algorithm can guide this process. Further studies are required to assess the benefit of routine revascularization, in combination to medical therapy, in this population.

RESUMEN

BACKGROUND: Recent evidence suggests that patients with herpes simplex virus (HSV) encephalitis may relapse because of autoimmunity against the N-methyl-D-aspartate receptor (NMDAR). We present a case series of post-HSV relapsing encephalopathy associated with antibodies to central nervous system (CNS) synaptic antigens. PATIENT/METHODS: Sera and cerebrospinal fluid (CSF) from five patients with HSV encephalitis who relapsed after antiviral therapy were tested for anti-NMDAR, gamma-aminobutyric acid b receptor (GABAbR), α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR), Leucine-rich, glioma inactivated 1 (LGI1), anti -contactin-associated protein-like 2 (CASPR2) and dipeptidyl-peptidase-like protein-6 (DDPX) antibodies using cell-based assays. RESULTS: Five patients (two infants, one child and two adults) developed post-HSV autoimmune encephalitis. The infants, aged 9 months and 10 months, after prompt and seemingly successful anti-HSV therapy, were readmitted with typical signs of NMDAR-encephalitis evolving within days, with NMDAR antibodies detected in both serum and CSF. Although they were promptly treated with intravenous immunoglobulin (IVIg) and with IVIg followed by rituximab, respectively, they were both left with psychomotor deficits. A 14-year-old girl with seizures due to HSV encephalitis improved with anti-HSV therapy. Later, she manifested intractable seizures and she was found positive for anti-NMDAR antibodies which persist. The two adults were women, aged 58 and 33 years. The first recovered after anti-HSV therapy and remained asymptomatic for 6 months, until she developed generalized seizures with persisting CSF anti-NMDAR antibodies; the second, who continued to be encephalopathic after 2 weeks of anti-HSV therapy, tested positive for anti-NMDAR antibodies in the serum and anti-GABAbR antibodies in the serum and CSF. She recovered fully following IVIg therapy but her serum anti-GABAbR antibodies persist 34 months later. DISCUSSION: Infection of the CNS with HSV can trigger CNS autoimmunity associated not only with anti-NMDAR but also with anti-GABAbR antibodies. These antibodies can persist in the serum, even without associated symptoms, but their presence in the CSF is firmly associated with disease development. In contrast to children and adults who responded well to therapies, the infants had an incomplete recovery with severe psychomotor deficits probably due to the interference of anti-NMDAR antibodies with neuro-developmental processes.

RESUMEN

IMPORTANCE: Heart failure (HF) is the leading cause of hospitalization among patients over the age of 65 in the United States and developed countries, posing a significant economic burden to the health care systems. More than half of the patients with HF will be readmitted to the hospital within 6 months from discharge, leading not only to increased health care related expenses but also functional decline, iatrogenic injuries and in-hospital infections. With the increasing prevalence of HF, there is a substantial need for innovative delivery care models that can provide hospital level of care at a patient's home. OBSERVATIONS: Home hospitalization was originally used to safely manage chronically ill patients with general medical (stroke, chronic obstructive pulmonary disease, deep vein thrombosis, community acquired pneumonia) and surgical conditions and was associated with improved patient satisfaction and improvement in activity of daily living status. This had no clear effect on readmission or cost. When hospital at home care model was applied to HF patients it demonstrated increased time to readmission, reduced index costs and improved health related quality of life, with no significant differences in adverse events. Eligible patients should be selected based on multiple factors taking into consideration applicable limitations and comorbidities. CONCLUSIONS AND RELEVANCE: Providing in-hospital level care to the patient's house presents a reliable alternative, yielding multiple benefits both for the patient, as well as the health care system. Formulating a well-defined model is necessary before wide implementation.

RESUMEN

PURPOSE OF REVIEW: Transcatheter aortic valve replacement (TAVR) has become an established therapy for patients with symptomatic severe aortic stenosis (AS). As the number of patients referred for TAVR increases, so does the prevalence of untreated obstructive coronary artery disease (CAD) in the population under evaluation. Despite the high prevalence of CAD in patients treated with TAVR, the management strategy of concomitant CAD in these patients remains an area of considerable uncertainty. RECENT FINDINGS: Percutaneous coronary intervention (PCI) in patients with CAD and severe AS has been shown to be feasible and safe. Whether revascularization before, during, or after TAVR is optimal remains a subject of debate. All three approaches represent valid strategies with advantages and disadvantages that need to be carefully weighed on an individual basis. Current expert opinions recommend that PCI should be performed before or at the time of TAVR as long as the risk of the procedure does not outweigh the potential benefits. The results of large clinical trials evaluating the optimal revascularization time are closely awaited.

RESUMEN

OBJECTIVE: This qualitative study explored the challenges that Greek parents/caregivers of children with controlled epilepsy (CwE) face regarding the disorder. METHODS: Interviews were conducted based on open-ended questions guided by a review of the literature. A total of 91 parents/caregivers were recruited by neurologists at the neurology clinics of two Athens public hospitals. A hermeneutic phenomenological approach was used to explore parent/caregiver experiences. The data were grouped and analyzed through a textual interpretation. RESULTS: Two key challenges were identified for parents of CwE: the disclosure of epilepsy and the absence of adequate information about coping with epilepsy. Parents in Greece were hesitant to reveal their child's epilepsy to school staff and their wider social milieu. Also, although satisfied with the patient-centered approach they experienced with their hospital doctor, parents/caregivers found that they needed more education about the existing sources of psychosocial and emotional support to cope with their child's epilepsy personally and as a family. Finally, the parents/caregivers who let their child know about the epilepsy and discussed the implications with the child found that parent-child communication improved. CONCLUSION: This study provides valuable insight into the impact of epilepsy on parents of CwE, which might help hospital and school staff support families with greater understanding, sensitivity, and skill. The findings suggest that Greek authorities should staff hospitals and schools with experts and more systematically advertise sources of information about epilepsy and ways to cope with it.

RESUMEN

BACKGROUND: Recent reports have suggested that advanced age may preclude favorable outcomes in transcatheter aortic valve replacement (TAVR), particularly when performed via transapical (TA) access. However, detailed examinations of TA-TAVR in nonagenarian patients are lacking in the contemporary literature. We therefore describe our experience with 25 consecutive nonagenarians who underwent TA-TAVR and report their short- and mid-term outcomes. METHODS: We identified all patients 90 years old or greater who underwent TA-TAVR between 2009-2014 at our institution. Demographic, comorbidity and echocardiographic data were obtained for all patients as were their in-hospital, 30-day, and 1-year outcomes. Overall survival was calculated using the Kaplan-Meier method. RESULTS: The mean Society of Thoracic Surgeons' predicted risk of mortality was 10.2% (SD±3.4). Twenty-four nonagenarians received TA-TAVR secondary to severe aortic stenosis while 1 had a valve-in-valve procedure for a regurgitant bioprosthetic valve. There were no conversions to open surgery, no aborted procedures, and no in-hospital deaths or strokes; 44% of patients (N.=11) were discharged to home. Five patients required cardiac rehospitalization within the first 30 days and 2 experienced strokes during the first year. Overall 30-day and 1-year survival were 100% and 83%, respectively. CONCLUSIONS: TA-TAVR can safely be performed on nonagenarians subjected to otherwise standard selection criteria. Chronology should not stand as a routine contraindication to this procedure; rather, comorbidities and functional status should define patient eligibility for TA-TAVR.

RESUMEN

OBJECTIVES: We sought to examine whether baseline diastolic dysfunction (DD) is associated with increased mortality in patients who develop aortic insufficiency (AI) after transcatheter aortic valve replacement (TAVR). BACKGROUND: Significant post-TAVR AI is associated with increased mortality, likely secondary to adverse hemodynamics secondary to volume overload and decreased LV compliance from chronic pressure overload. However, the effect of baseline DD on outcomes of patients with post-TAVR AI has not been studied. METHODS: A total of 195 patients undergoing TAVR were included in the study. Patients with moderate-to-severe mitral stenosis, prior mitral valve replacement or atrial fibrillation were excluded. DD was classified at baseline by a 2-step approach as recommended by the American Society of Echocardiography while AI was evaluated 30 days post-TAVR. Follow up data up to 2 years post-TAVR was used in survival analysis. RESULTS: Patients with severe baseline DD who developed ≥mild post-TAVR AI had increased mortality compared to all other patients (HR = 3.89, CI: 1.76-8.6, P = 0.001), which remained significant after adjusting for post-TAVR AI, pre-TAVR AI, baseline mitral regurgitation, ejection fraction, pulmonary artery pressure, creatinine clearance and history of stroke. CONCLUSIONS: Even mild post-TAVR AI may have a negative impact on outcomes of patients with underlying severe DD. © 2016 Wiley Periodicals, Inc.

RESUMEN

BACKGROUND: Paravalvular aortic regurgitation (PAR) remains a common complication following transcatheter aortic valve replacement (TAVR), and has been associated with increased mortality. Adverse left ventricular (LV) remodelling has been reported in patients with post-TAVR PAR, but the association between adverse LV remodeling and increased mortality remains unclear. The aim of the present study was to examine the association between PAR, LV remodeling and mortality following TAVR in a non-PARTNER (Placement of Aortic Transcatheter Valves) trial population. METHODS: A total of 195 patients that underwent TAVR was included in the study. The LV ejection fraction (LVEF), LV mass index (LVMI), LV internal dimension at systole (LVIDs) and diastole (LVIDd) were compared between patients with different degrees of PAR at baseline, and at one month and one year after TAVR. Survival analysis was performed for different degrees of PAR and LV remodeling. RESULTS: PAR ≥moderate was associated with increased mortality (HR 4.58 [1.80-11.63], p = 0.001), but PAR >mild was not. The LVIDd and LVIDs were persistently increased at one year after TAVR in patients with PAR >mild compared to those with PAR ≤mild (5.9 ± 0.8 cm versus 5.4 ± 0.7 cm, p = 0.02 and 4.4 ± 0.8 cm versus 3.9 ± 0.8, p = 0.03, respectively). The LVEF was improved similarly between the two groups at one year after TAVR (p = 0.1). Patients with PAR ≥moderate had significantly more adverse LV remodeling at one month after TAVR in terms of LVIDd, LVIDs, and LVMI. The degree of remodeling as expressed in terms of LVIDd, LVIDs, LVMI and LVEF changes from baseline did not have a direct impact on mortality. CONCLUSIONS: A worse PAR was associated with more adverse LV remodeling and a higher mortality after TAVR in a non-PARTNER patient population.

RESUMEN

BACKGROUND: Transapical approach (TA) is an established access alternative to the transfemoral technique in patients undergoing transcatheter aortic valve replacement (TAVR) for treatment of symptomatic aortic valve stenosis. The impact of prior coronary artery bypass grafting (CABG) on clinical outcomes in patients undergoing TA-TAVR is not well defined. METHODS: A single center retrospective cohort analysis of 126 patients (male 41%, mean age 85.8 ± 6.1 years) who underwent TA balloon expandable TAVR (Edwards SAPIEN, SAPIEN XT or SAPIEN 3) was performed. Patients were classified as having prior CABG (n = 45) or no prior CABG (n = 81). Baseline clinical characteristics, in-hospital, 30-day, 6 months and one-year clinical outcomes were compared. RESULTS: Compared to patients without prior CABG, CABG patients were more likely to be male (62.2 vs. 29.6%, p < 0.001) with a higher STS score (11.66 ± 5.47 vs. 8.99 ± 4.19, p = 0.003), history of myocardial infarction (55 vs. 21.1%, p < 0.001), implantable cardioverter defibrillator (17.8 vs. 3.7%, p = 0.017), left main coronary artery disease (42.2 vs. 4.9%, p < 0.001), and proximal left anterior descending coronary artery stenosis (57.8 vs. 16%, p < 0.001). They also presented with a lower left ventricular ejection fraction (%) (42.3 ± 15.3 vs. 54.3 ± 11.6, p < 0.01) and a larger effective valve orifice area (0.75 ± 0.20 cm2 vs. 0.67 ± 0.14 cm2, p = 0.025). There were no intra-procedural deaths, no differences in stroke (0 vs. 1.2%, p = 1.0), procedure time in hours (3.50 ± 0.80 vs. 3.26 ± 0.86, p = 0.127), re-intubation rate (8.9 vs. 8.6% p = 1.0), and renal function (highest creatinine value 1.73 ± 0.71 mg/ml vs.1.88 ± 1.15 mg/ml, p = 0.43). All-cause mortality at 6 months was similar in both groups (11.4, vs. 17.3% p = 0.44), and one-year survival was 81.8 and 77.8% respectively (p = 0.51). On multivariate analysis, the only factor significantly associated with one-year mortality was prior history of stroke (HR, 2.76; 95% CI, 1.06-7.17, p = 0.037). CONCLUSION: Despite the higher baseline clinical risk profile, patients with history of prior CABG undergoing TA-TAVR had comparable in-hospital, 6 months and one-year clinical outcomes to those without prior CABG.

RESUMEN

OPINION STATEMENT: The volume of cardiac diagnostic procedures involving the use of ionizing radiation has increased rapidly in recent years, and the radiation exposure experienced by patients undergoing any medical imaging procedure has recently obtained a growing attention. Transradial (TR) access is being increasingly used worldwide for diagnostic coronary angiography (CA), and percutaneous coronary interventions, since it offers several benefits as compared to transfemoral (TF) access, such as by reducing hemostasis time and vascular complications, increased patient comfort, reduced hospital stay, and lower cost. In contrast, TR CA is thought to be associated with increased radiation exposure parameters compared with the traditional TF access. Although experienced operators may almost counterbalance this shortcoming, the increase in radiation exposure associated with TR approach seems not to be present in most clinical settings.

RESUMEN

AIM: The aim of this study was to explore the sources of information for the educators in Greek primary and secondary schools with regard to epilepsy, first aid to seizures, and pupils' health conditions. METHOD: A semistructured anonymous 52-item questionnaire was sent to 100 public primary and secondary Greek schools from all districts. Two thousand thirty-seven teachers were approached; 446 questionnaires returned. The data were analyzed with SPSS20. Also, 70 head teachers were phone-interviewed with an open-ended unstructured questionnaire. The derived data were analyzed using mixed methodology. RESULTS: Twenty-two percent of the addressed educational community responded to the questionnaire, mostly women (66.6%). More responses came from urban areas (71.5%). The main source for the teachers to obtain information about epilepsy was found to be personal experience (37.75%) and internet (34.93%). Only a small percentage was referred to courses (6.2%). Eighty point three percent of the educators knew what epilepsy is, and 88.1% had the right view about the nature of the illness. However, 92% of the educators replied that they have not had adequate first aid training. Although 80.3% of the teachers believed that the school personnel are aware of the pupils' medical history, 85.48% of the teachers considered that they are informed about the pupils' condition from the parents/carers, and only 5.53% believed that the information came from the family doctor. Ninety-five point seventy percent of the educators declared a wish for further information and training about epilepsy. CONCLUSION: Knowledge and attitudes of the educators towards epilepsy are improved compared with those reported in previous studies conducted in Greece. However, there are still areas of uncertainty which need improvement. The necessity for more information about epilepsy and pupils' medical history along with appropriate training about seizure incidents seems crucial for the Greek educational community. Educational campaigns about epilepsy could improve teachers' knowledge of epilepsy to develop a well-informed and tolerant community. Further research in the field is necessary to provide teachers with accurate information about the illness and the ways to cope with it.
