RESUMO
Covered stent correction of a superior sinus venosus atrial septal defect is increasingly performed as an alternative to surgical repair. While sinus node dysfunction requiring pacemaker implantation may be required after surgical repair, this has not been previously reported after covered stent implantation. We reviewed the experience in two interventional centers. Balloon inflation in the superior vena cava was used to confirm the anomalous pulmonary vein drainage would be unobstructed after stent implantation. During balloon testing in 62 consecutive patients, we assessed gradients across the pulmonary vein to left atrium while monitoring the rhythm. We observed the outcomes after covered stent correction in 51 patients. In a single patient, significant bradycardia and pauses developed on repeat balloon testing and the procedure was abandoned without stent implantation. In another patient, there was no sign of sinus node dysfunction during balloon testing but several hours after stent implantation, the patient became symptomatic from sinus bradycardia and pauses and had a pacemaker implanted 3 days later. Over a year later there are some signs of improvement in sinus node function. While sinus node dysfunction has not been described previously during balloon testing or after stent implantation, this report demonstrates for the first time that it may occur. Larger registries are therefore required to monitor for this uncommon complication.
RESUMO
OBJECTIVE: This study explores the reappraisal of personal values among people with cancer post-diagnosis and its connections to meaningfulness, encompassing personal meaning and sense of meaning, and various dimensions of quality of life. METHODS: A total of 144 patients with diverse cancer types and a control group comprising 158 healthy adults with similar demographic characteristics completed the Valued Living Questionnaire-Perceived Change, the Personal Meaning Profile-Brief, the Portrait Values Questionnaire, and the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being. RESULTS: Cancer patients displayed a substantial values reappraisal compared to healthy adults. They reported an increased significance of social areas and self-transcendental values, including close relationships (family, partner, and friends), spirituality, citizenship, and universalism, as well as an increased importance of self-care and self in general. Conversely, cancer patients assigned less importance to work and self-enhancement values such as stimulation, power, and achievement. Cluster analysis revealed that patients who reappraised their values exhibited higher meaningfulness and better indicators of quality of life, including spiritual and physical well-being, compared to patients who did not modify their value system. CONCLUSIONS: These findings underscore the importance of assessing and promoting meaning-in-life adaptability among people with cancer, with potential applications in meaning-centered therapies and interventions aimed at enhancing psychological flexibility.

PURPOSE: The aim of the study was to analyze the surgical outcome of patients with total anomalous pulmonary venous connection (TAPVC) who underwent cardiac surgery. METHODS: A retrospective study was carried out. Patients with diagnosis of TAPVC undergoing cardiac surgery at the National Institute of Cardiology Ignacio Chávez, from January 1, 2003 and June 30, 2019 were included. Descriptive statistics were calculated, as well as a bivariate analysis of the variables associated with mortality. A logistic regression model was included to determine risk factors associated with the main outcome and survival was analyzed using the Kaplan-Meier method. RESULTS: A total of 5314 patients diagnosed with congenital heart disease (CHD) underwent surgery, 414 (7.8%) were patients with TAPVC, with an average age of 17.1 ± 34.6 months, 58.2% were male. It was frequent in infants (61.6%) and preschool (19.6%). Predominant type was supracardiac TAPVC (47.4%). Pulmonary venous obstruction (PVO) occurred in 32.1%. Risk factors associated with mortality were infracardiac TAPVC (odds ratio [OR]: 3.26; 95% confidence interval [CI]: 1.17-9.03; p = .02), PVO (OR: 2.56; 95% CI: 1.05-6.22; p = .03) and postoperative mechanical ventilation (OR: 1.005; 95% CI: 1.002-1.008; p = .01). Overall survival was 87.2%, with better outcomes in adolescents (100%), children (94.1%), mixed TAPVC (96%), and cardiac TAPVC (91.9%; p < .001). CONCLUSIONS: The survival of our institution after surgical correction of TAPVC is similar to that of other referral centers, where patients with infracardiac TAPVC and newborns worse outcomes. All patients must undergo a rigorous evaluation to determine an adequate repair strategy.

This study examined the roles of anxiety, experiential avoidance and meaning in life in the abusive use of social networks. Participants in the study (N = 235: 172 women, 62 men, 1 non-binary) volunteered to complete a brief online survey measuring experiential avoidance, anxiety and meaning in life. Correlational and linear regression analyses were performed controlling for age in both the total sample and the subsamples of men and women. The partial correlation analyses showed that, once age was controlled for experiential avoidance, anxiety and meaning in life were related to the abusive use of social networks in women, while for men, only anxiety was significant. For women the linear regression equation which best predicted abusive use of social networks included little meaning in life and high experiential avoidance. For men, only anxiety was a possible predictive factor of abusive use of social networks. These results are discussed with regard to existing research on abusive use of social networks, noting the possible protective effect of meaning in life and calling greater attention to gender differences in behaviors related to online social networks.
El presente estudio examinó el papel de la ansiedad, la evitación experiencial y el sentido vital en el uso abusivo de redes sociales. Los participantes (N = 235: 172 mujeres, 62 hombres, 1 no-binario) completaron una breve encuesta dirigida a medir la evitación experiencial, la ansiedad y el sentido vital. Se llevaron a cabo análisis de regresión lineal y correlaciones controlando la influencia de la edad tanto para hombres como para mujeres. Los análisis de correlación parcial mostraron que, una vez controlada la edad de los participantes, tanto la evitación experiencial como la ansiedad y el sentido vital estuvieron relacionados con el uso abusivo de redes sociales en mujeres; sin embargo, para los varones, sólo la ansiedad se relacionó con un mayor uso de redes sociales. Para las mujeres la ecuación de regresión lineal que mejor predijo el uso abusivo de redes sociales incluyó un bajo sentido vital y una elevada evitación experiencial, mientras que para los varones sólo la ansiedad predijo el mayor uso de redes sociales. Los resultados obtenidos se discuten en relación con la investigación existente sobre el uso de las redes sociales, destacando el sentido vital como un posible factor protector y la importancia de una perspectiva de género para estudiar las redes sociales en línea.

PURPOSE: The aim of the study was to identify, determine, and analyze the clinical and surgical outcomes of patients with atrial isomerism (AI) undergoing cardiac surgery. METHODS: A retrospective study was carried out. Patients with diagnosis of AI undergoing cardiac surgery at the National Institute of Cardiology Ignacio Chávez, from January 1, 2010 and March 31, 2020 were included; demographic characteristics and perioperative conditions of the patients were considered. RESULTS: Sixty-five patients were included, with an average age of 6.4 ± 4.9 years, 50.8% males. Thirty-eight (58.5%) had right atrial isomerism (RAI) and 27 (41.5%) had left atrial isomerism (LAI); univentricular physiology (78.5%) predominated. Atrioventricular septal defect (AVSD) in RAI and septal defects in LAI were identified as the main associated defects. The most common surgical procedures performed were modified Blalock-Taussig shunt (MBTS) (27.6%), MBTS with total anomalous pulmonary venous connection (TAPVC) repair (15.3%) and total cavopulmonary connection (TCPC) with an extracardiac conduit fenestrated (10.8%); 100% RAI required a univentricular approach, while in LAI it was 48.1%. Overall survival was 92.3%, with 100% survival in LAI with biventricular physiology and 86.8% in RAI with univentricular physiology. CONCLUSIONS: The survival of our institution is similar to that of other referral centers, where patients with LAI had a better evolution than RAI; in addition, the univentricular approach was required in all with RAI. Patients with AI must undergo a rigorous evaluation to determine an adequate repair strategy, considering univentricular RAI with a high possibility of morbidity and mortality.

OBJECTIVES: To demonstrate safety and efficacy of using different generations of softer Amplatzer™ devices for ventricular septal defect (VSD) closure to avoid serious complications at follow-up. BACKGROUND: Transcatheter closure of perimembranous ventricular septal defects (PmVSD) is a well-established procedure; however, it is associated with unacceptable incidence of complete heart block. Great advantages have been achieved by using softer devices for VSD transcatheter closure. The first and second generation of Amplatzer™ occluders (AVP II, ADO, and ADO II) seem to offer a safe and attractive alternative for this procedure. These devices can be delivered using either an arterial (retrograde) or venous (prograde) approach. METHODS AND RESULTS: Patients with congenital PmVSD who underwent transcatheter closure using ADO, ADO II, and AVP II devices were included. Primary end point was to determine efficacy and safety of these generations of devices and to determine the incidence of complications at follow-up (complete AV block and aortic/tricuspid/mitral regurgitation). One hundred and nineteen patients underwent VSD closure at a median age of 5 years (8 months-54 years). During the catheterization, there were only minor complications and at follow-up of 36 ± 25.7 months (up to 99 months), the closure rate was high of 98.3% and freedom from AV block was 100%. CONCLUSIONS: The use of softer Amplatzer™ devices is a good alternative to achieve PmVSD closure safely with no risk of AVB during the procedure or at midterm follow-up.

In toxin-based models of Parkinson's disease (PD), striatal projection neurons (SPNs) exhibit dendritic atrophy and spine loss concurrent with an increase in excitability. Chronic l-DOPA treatment that induces dyskinesia selectively restores spine density and excitability in indirect pathway SPNs (iSPNs), whereas spine loss and hyperexcitability persist in direct pathway SPNs (dSPNs). These alterations have only been characterized in toxin-based models of PD, raising the possibility that they are an artifact of exposure to the toxin, which may engage compensatory mechanisms independent of the PD-like pathology or due to the loss of dopaminergic afferents. To test all these, we studied the synaptic remodeling in Pitx3-/- or aphakia mice, a genetic model of PD, in which most of the dopamine neurons in the substantia nigra fail to fully differentiate and to innervate the striatum. We made 3D reconstructions of the dendritic arbor and measured excitability in identified SPNs located in dorsal striatum of BAC-Pitx3-/- mice treated with saline or l-DOPA. Both dSPNs and iSPNs from BAC-Pitx3-/- mice had shorter dendritic trees, lower spine density, and more action potentials than their counterparts from WT mice. Chronic l-DOPA treatment restored spine density and firing rate in iSPNs. By contrast, in dSPNs, spine loss and hyperexcitability persisted following l-DOPA treatment, which is similar to what happens in 6-OHDA WT mice. This indicates that dopamine-mediated synaptic remodeling and plasticity is independent of dopamine innervation during SPN development and that Pitx3-/- mice are a good model because they develop the same pathology described in the toxins-based models and in human postmortem studies of advanced PD.SIGNIFICANCE STATEMENT As the only genetic model of Parkinson's disease (PD) that develops dyskinesia, Pitx3-/- mice reproduce the behavioral effects seen in humans and are a good system for studying dopamine-induced synaptic remodeling. The studies we present here establish that the structural and functional synaptic plasticity that occur in striatal projection neurons in PD and in l-DOPA-induced dyskinesia are specifically due to modulation of the neurotransmitter dopamine and are not artifacts of the use of chemical toxins in PD models. In addition, our findings provide evidence that synaptic plasticity in the Pitx3-/- mouse is similar to that seen in toxin models despite its lack of dopaminergic innervation of the striatum during development. Pitx3-/- mice reproduced the alterations described in patients with advanced PD and in well accepted toxin-based models of PD and dyskinesia. These results further consolidate the fidelity of the Pitx3-/- mouse as a PD model in which to study the morphological and physiological remodeling of striatal projection neurons by administration of l-DOPA and other drugs.

The dopamine D3 receptor (D3R) belongs to the dopamine D2-like receptor family and is principally located in the ventral striatum. However, previous studies reported D3R overexpression in the dorsal striatum following l-DOPA treatment in parkinsonian animals. This fact has drawn attention in the importance of D3R in l-DOPA-induced dyskinesia (LID). Here, we used D3R knockout mice to assess the role of D3R in LID and rotational sensitization in the hemiparkinsonian model. Mice lacking D3R presented a reduction in dyskinesia without interfering with the antiparkinsonian l-DOPA effect and were accompanied by a reduction in the l-DOPA-induced rotations. Interestingly, deleting D3R attenuated important molecular markers in the D1R-neurons such as FosB, extracellular signal-regulated kinase, and histone-3 (H3)-activation. Colocalization studies in D1R-tomato and D2R-green fluorescent protein BAC-transgenic mice indicated that l-DOPA-induced D3R overexpression principally occurs in D1R-containing neurons although it is also present in the D2R-neurons. Moreover, D3R pharmacological blockade with PG01037 reduced dyskinesia and the molecular markers expressed in D1R-neurons. In addition, this antagonist further reduced dyskinetic symptoms in D1R heterozygous mice, indicating a direct interaction between D1R and D3R. Together, our results demonstrate that D3R modulates the development of dyskinesia by targeting D1R-mediated intracellular signaling and suggest that decreasing D3R activity may help to ameliorate LID.

Catechol-O-methyltransferase (COMT) degrades dopamine and its precursor l-DOPA and plays a critical role in regulating synaptic dopamine actions. We investigated the effects of heightened levels of COMT on dopamine-regulated motor behaviors and molecular alterations in a mouse model of dyskinesia. Transgenic mice overexpressing human COMT (TG) and their wildtype (WT) littermates received unilateral 6-OHDA lesions in the dorsal striatum and were treated chronically with l-DOPA for two weeks. l-DOPA-induced dyskinesia was exacerbated in TG mice without altering l-DOPA motor efficacy as determined by contralateral rotations or motor coordination. Inductions of FosB and phospho-acetylated histone 3 (molecular correlates of dyskinesia) were potentiated in the lesioned striatum of TG mice compared with their WT littermates. The TG mice had lower basal levels of dopamine in the striatum. In mice with lesions, l-DOPA induces a greater increase in the dopamine metabolite 3-methoxytyramine in the lesioned striatum of dyskinetic TG mice than in WT mice. The levels of serotonin and its metabolite were similar in TG and WT mice. Our results demonstrate that human COMT overexpression confers a heightened susceptibility to l-DOPA-induced dyskinesia and alters molecular and neurochemical responses in the lesioned striatum of mice.

Complications of transseptal puncture are significant and potentially life threatening. Aortic perforation is one of these complications and it needs to be repaired immediately. We report the case of a 48-year-old female with a history of rheumatic mitral valve disease. She underwent three previous mitral valve replacements. Her last echocardiogram reported an anterolateral leak in the mitral prosthesis. Catheterization was performed. During the procedure, when attempting to perform transseptal puncture, catheterization was complicated by a forcefully puncture of the aortic root by the Brockenbrough needle followed by an immediately advancement of an 8-Fr Mullins sheath. We decided to leave the 8-Fr sheath in the aortic root recognizing the danger of removing the sheath and finally we advanced a 6/4 mm Amplatzer ductal occluder (ADO I) through the Mullins sheath and under fluoroscopy and TEE guidance we achieved a successful deployment of the device and closure of the perforation. Subsequently, the paravalvular leak was closed with an Amplatzer Vascular Plug (AVP III 10/5 mm). There are only three cases of a similar technique for the same injury in which the authors describe successful closing of aortic perforation with percutaneous closure devices. Our case is the first described during a mitral paravalvular leak closure. It is also the first to describe a different technique of leaving the Mullins sheath in the aortic root and advancing the Amplatzer device through it to achieve successful closure of the aortic perforation. We preferred the percutaneous closure over open-heart repair. © 2015 Wiley Periodicals, Inc.

BACKGROUND: Percutaneous closure of patent ductus arteriosus has become the treatment of choice in many centres. In patients with large ducts and pulmonary hypertension, transcatheter closure has been achieved with success using the Amplatzer Duct Occluder or even the Amplatzer Muscular Ventricular Septal Defect Occluder. MATERIALS AND METHODS: We present a series of 17 patients with large and hypertensive ductus arteriosus who were treated with an Amplatzer Septal Occluder. The group had 11 female patients (64.7%) and a mean age of 18.6±12.1 years. RESULTS: The haemodynamic and anatomical data are as follows: pulmonary artery systolic pressure 71.3±31.8 mmHg, pulmonary to systemic flow ratio 3.14±1.36, ductal diameter at the pulmonary end 12.5±3.8 mm, and at the aortic end 20.2±7.7 mm; 14 cases (82.3%) had type A ducts. In 11 patients, we began the procedure using a different device - six with duct occluder and five with ventricular septal occluder - and it was changed because of device embolisation in six (35.3%). All septal occluders were delivered successfully. Residual shunt was moderate in six patients (35.3%), mild in eight (47%), trivial in two (11.8%), and no shunt in one (5.9%). Pulmonary systolic pressure decreased to 48.9±10.8 mmHg after occlusion (p=0.0015). Follow-up in 15 patients (88.2%) for 28.4±14.4 months showed complete closure in all cases but one, and continuous decrease of the pulmonary systolic pressure to 31.4±10.5 mmHg. No complications at follow-up have been reported. CONCLUSIONS: The Amplatzer Septal Occluder is a good alternative to percutaneously treat large and hypertensive ductus arteriosus.

Dopamine replacement therapy in Parkinson's disease is associated with several unwanted effects, of which dyskinesia is the most disabling. The development of new therapeutic interventions to reduce the impact of dyskinesia in Parkinson's disease is therefore a priority need. This review summarizes the key molecular mechanisms that underlie dyskinesia. The role of dopamine receptors and their associated signaling mechanisms including dopamine-cAMP-regulated neuronal phosphoprotein, extracellular signal-regulated kinase, mammalian target of rapamycin, mitogen and stress-activated kinase-1 and Histone H3 are summarized, along with an evaluation of the role of cannabinoid and nicotinic acetylcholine receptors. The role of synaptic plasticity and animal behavioral results on dyskinesia are also evaluated. The most recent therapeutic advances to treat Parkinson's disease are discussed, with emphasis on the possibilities and limitations of non-pharmacological interventions such as physical activity, deep brain stimulation, transcranial magnetic field stimulation and cell replacement therapy. The review suggests new prospects for the management of Parkinson's disease-associated motor symptoms, especially the development of dyskinesia. This review aims at summarizing the key molecular mechanisms underlying dyskinesia and the most recent therapeutic advances to treat Parkinson's disease with emphasis on non-pharmacological interventions such as physical activity, deep brain stimulation (DBS), transcranial magnetic field stimulation (TMS) and cell replacement therapy. These new interventions are discussed from both the experimental and clinical point of view, describing their current strength and limitations.

INTRODUCTION: Schizotypy is a psychological construct related to schizophrenia. The exact relationship between both entities is not clear. In recent years, schizophrenia has been associated with hippocampal abnormalities and spatial memory problems. The aim of this study was to determine possible links between high schizotypy (HS) and low schizotypy (LS) and spatial abilities, using virtual reality tasks. We hypothesised that the HS group would exhibit a lower performance in spatial memory tasks than the LS group. METHODS: Two groups of female students were formed according to their score on the ESQUIZO-Q-A questionnaire. HS and LS subjects were tested on two different tasks: the Boxes Room task, a spatial memory task sensitive to hippocampal alterations and a spatial recognition task. RESULTS: Data showed that both groups mastered both tasks. Groups differed in personality features but not in spatial performance. These results provide valuable information about the schizotypy-schizophrenia connections. CONCLUSION: Schizotypal subjects are not impaired on spatial cognition and, accordingly, the schizotypy-schizophrenia relationship is not straightforward.

BACKGROUND: Magical thinking consists of accepting the possibility that events that, according to the causal concepts of a culture, cannot have any causal relationship, but might somehow nevertheless have one. Magical thinking has been related to both obsessive-compulsive disorder and schizophrenia. AIMS: The purpose of this study was to investigate the role of magical thinking in hallucinations of patients diagnosed with schizophrenia. METHODS: Four groups were recruited for this purpose from a clinical population (hallucinating schizophrenic patients, patients diagnosed with psychoses who had never hallucinated, obsessive-compulsive disorder patients and a clinical control group) and a non-clinical control group, who were given the Magical Ideation Scale. RESULTS: The results show that magical ideation differentiates the group of schizophrenic patients with auditory hallucinations from the rest of the groups that participated in the design. Items related to "mind reading", to the presence of auditory illusions in response to sound stimuli, and to the sense of sometimes being accompanied by an evil presence are the most closely related to the presence of auditory hallucinations. CONCLUSIONS: Magical thinking, understood as beliefs in non-consensual modes of causation, is closely linked to auditory hallucinations in patients diagnosed with schizophrenia.

The purpose of this study was to examine the relationship between childhood traumas, mindfulness, and dissociation (more specifically, absorption and depersonalization) in healthy subjects with and without hallucination proneness. A sample of 318 subjects was given the Launay-Slade Hallucination Scale-Revised (R. P. Bentall & P. Slade, 1985). From this sample, 2 groups were formed: one with high and the other with low hallucination proneness. Furthermore, all participants were given the Tellegen Absorption Scale (A. Tellegen & G. Atkinson, 1974), the Cambridge Depersonalization Scale (M. Sierra & G. E. Berrios, 2000), the Southampton Mindfulness Questionnaire (P. D. J. Chadwick et al., 2008), and the Trauma Questionnaire (J. R. E. Davidson, D. Hughes, & D. G. Blazer, 1990). The results showed that in the group with high hallucination proneness, there were significantly more subjects with traumatic experiences than in the group with low predisposition, although no significant difference in the mean number of traumatic experiences undergone in childhood was found between the 2 groups, although there was a trend toward significance. A correlation analysis showed a significant negative association between mindfulness on the one hand and absorption and depersonalization on the other. A positive relationship was also found between childhood traumas and absorption and depersonalization. Finally, multiple mediation analysis showed that the absorption and depersonalization variables acted as mediators between childhood traumas and hallucination proneness. We discuss the importance of the relationship between the variables studied and hallucination proneness and suggest some approaches for their treatment.

INTRODUCTION: The purpose of this work was to study the relationship of absorption, depersonalisation, and self-focused attention in subjects prone to hallucination. METHODS: A sample of 218 healthy subjects was given the LSHS-R Hallucination Scale (Bentall & Slade, 1985). Three groups, subjects with high, medium, and low hallucination proneness, were formed from this sample. The Tellegen Absorption Scale (TAS; Tellegen & Atkinson, 1974), Cambridge Depersonalisation Scale (CDS; Sierra & Berrios, 2000), and Self-Absorption Scale (SAS; McKenzie & Hoyle, 2008) were also given to all the participants. The Metacognitions Questionnaire (MCQ-30; Wells & Cartwright-Hatton, 2004) was used as a covariant to control for the effects of emotional vulnerability on the dependent variables studied. RESULTS: The results showed that subjects highly prone to hallucinations had significantly higher absorption, depersonalisation, and self-focused attention than the subjects in the other two groups. A hierarchical regression analysis showed that absorption and depersonalisation predict hallucination proneness. CONCLUSIONS: The importance of the absorption, depersonalisation, and self-focused attention variables for understanding the aetiology of hallucinations is discussed in the Conclusions, where some approaches to its treatment are also suggested.

Mindfulness practice and mindfulness-based interventions are widely known, especially for women's sexuality. However, it is currently unknown how this practice affects the experience of male sexuality, possibly due to the existence of pharmacological treatments that are usually the first choice of treatment for men. The objectives of this study are to explore the influence of mindfulness on different components of men's sexuality from a scoping review of relevant scientific articles existing in the literature. A literature search from 2010 to 2022 was carried out in the electronic databases MEDLINE, Embase, PsycINFO, Web of Science, Scopus, PubMed, Dialnet, SciELO Citation Index, and Redalyc. Out of the 238 studies, 12 that met the defined selection criteria were selected. The analysis of these studies seems to indicate that the practice of mindfulness favours different variables of male sexuality, such as satisfaction and sexual functioning or genital self-image. Mindfulness-based interventions represent a valuable and promising contribution. No adverse effects were detected from the review of scientific articles considered in this work. Nevertheless, more randomized studies with active control groups are necessary to establish the benefits of mindfulness-based interventions in sex therapy for men.

Background: Down syndrome is the most common chromosomal abnormality, it is associated with a wide variety of congenital heart defects, being considered as clinical elements of high infant morbidity and mortality. Objective. Objective: To describe the clinical outcomes of patients with Down syndrome undergoing surgery and interventionism as treatment for congenital heart disease at this Institution. Material and methods: 368 patients with Down syndrome and associated congenital heart disease were diagnosed. The variables studied were weight, stature, sex, age, type of heart disease, corrective procedure, length of stay in the hospital and intensive care unit, morbidity and mortality. Results: 368 pediatric patients underwent surgical or interventional correction. Of which 197 (54%) were female, the median age was 24 months (interquartile range [IQR]: 14-48) in the surgical group and 36 months (IQR: 17-85) in the interventional group. The most frequent congenital heart diseases were: PCA (31%), IVC (28%), CAV (20%), ASD (16%) and tetralogy of Fallot with 4% respectively. Hospital stay was 9 days (IQR: 7-15) in the surgical group and 3 days (IQR: 2-5) in the hemodynamic group. Morbidities were postoperative infection in 30 patients (14%) and complete atrioventricular block in 19 patients (9%). Overall mortality including both surgical and interventional was 2%. Conclusions: The therapeutic, surgical and interventional results in children with Down syndrome and congenital heart disease have improved very satisfactorily. The lower prevalence of the atrioventricular canal in the Mexican population is noteworthy. It is essential to carry out a cardiological evaluation of children with Down syndrome and those with congenital heart disease to correct them in a timely manner to promote survival and quality of life.
Antecedentes: El síndrome de Down es la anomalía cromosómica más frecuente y se asocia con defectos cardiacos congénitos, elementos clínicos de una alta morbilidad y mortalidad infantil. Objetivo: Describir los desenlaces clínicos de los pacientes con síndrome de Down sometidos a cirugía e intervencionismo como tratamiento de las cardiopatías congénitas en esta institución. Material y métodos: Estudio retrospectivo que incluyó pacientes menores de 18 años con síndrome de Down y patología cardiaca asociada durante los últimos 10 años. Las variables estudiadas fueron: peso, talla, sexo, edad, tipo de cardiopatía, procedimiento correctivo, tiempo de estancia intrahospitalaria y en unidad de terapia intensiva, morbilidad y mortalidad. Resultados: 368 pacientes pediátricos fueron llevados a corrección quirúrgica o intervencionista, de los cuales 197 (54%) pertenecían al sexo femenino, la mediana de edad fue de 24 meses (rango intercuartílico [RIQ]: 14-48) en el grupo quirúrgico y de 36 meses (RIQ: 17-85) en el intervencionista. Las cardiopatías congénitas más frecuentes fueron: persistencia del conducto arterioso (31%), comunicación interventricular (28%), canal atrioventricular (CAV) (20%), comunicación interauricular (16%) y tetralogía de Fallot con el 4% respectivamente. La estancia hospitalaria fue de 9 días (RIQ: 7-15) en el grupo quirúrgico y de 3 días (RIQ: 2-5) en el hemodinámico. Las morbilidades fueron infección postoperatoria en30 pacientes (14%) y en 19 pacientes (9%) bloqueo atrioventricular completo. La mortalidad global incluyendo tanto el quirúrgico como el intervencionista fue del 2%. Conclusiones: Los resultados terapéuticos, quirúrgicos e intervencionistas, enlos niños con síndrome de Down y cardiopatías congénitas han mejorado en forma muy satisfactoria. Es de destacar lamenor prevalencia del CAV en la población mexicana. Es indispensable realizar evaluación cardiológica a los niños consíndrome de Down y aquellos con cardiopatías congénitas llevarlos a corrección de manera oportuna para favorecer la sobrevida y calidad de vida.

The TBX20 gene has a key role during cardiogenesis, and it has been related to epigenetic mechanisms in congenital heart disease (CHD). The purpose of this study was to assess the association between DNA methylation status and congenital septal defects. The DNA methylation of seven CpG sites in the TBX20 gene promoter was analyzed through pyrosequencing as a quantitative method in 48 patients with congenital septal defects and 104 individuals with patent ductus arteriosus (PDA). The average methylation was higher in patients than in PDA (p < 0.001). High methylation levels were associated with a higher risk of congenital septal defects (OR = 4.59, 95% CI = 1.57-13.44, p = 0.005). The ROC curve analysis indicated that methylation of the TBX20 gene could be considered a risk marker for congenital septal defects (AUC = 0.682; 95% CI = 0.58-0.77; p < 0.001). The analysis of environmental risk factors in patients with septal defects and PDA showed an association between the consumption of vitamins (OR = 0.10; 95% CI = 0.01-0.98; p = 0.048) and maternal infections (OR = 3.10; 95% CI = 1.26-7.60; p = 0.013). These results suggest that differences in DNA methylation of the TBX20 gene can be associated with septal defects.
