[Incidence and evolution of congenital heart disease in Spain from 2003 until 2012]

Perioperative stress and anxiety in parents of children operated on for congenital heart disease

INTRODUCTION

Levels of stress and anxiety suffered by parents of children with congenital heart disease (PCUCS) during their children's admission for cardiac surgery may be higher than those suffered by other parents who go through the same experience.

OBJECTIVE

General objective of this study was to measure the stress and anxiety suffered by PCUCS and parents of children undergoing renal surgery (PCURS) in relation to the intervention of their children. The specific objective of the quantitative study was to compare global stress and anxiety according to sex, time of the perioperative period, and cohort. The general objective of the qualitative section is to explore the experience that PCUCS and PCURS have during their hospital stay and to identify the specific factors that influence the genesis of stress and anxiety.

METHOD

A cohort study was carried out in which PCURS and PCUCS were included. The quantitative part was performed by comparing the scores of three questionnaires that measure stress levels (PSS-14), state anxiety (STAIE) and trait anxiety (STAIR) throughout three perioperative moments. At the same time, a qualitative study was carried out with semi-structured interviews and collection of diaries on which a descriptive phenomenological analysis was carried out, according to Munhall. The analysis of the text was carried out according to Colaizzi.

RESULTS

Stress and anxiety levels were significantly higher in PCUCS compared to PCURS. Mothers in the cardiac cohort were those with the highest scores on all scales. In the qualitative study, four themes emerged: "stress and anxiety from the moment of diagnosis", "surgical intervention as a critical moment", "harshness of the postoperative period in the Intensive Care Unit" and "joy and gratitude versus dependence and fear for the future".

CONCLUSIONS

PCUCS suffer higher levels of stress and anxiety than PCURS, being the mothers of the cardiac cohort those who suffer these disorders with greater intensity. This study can constitute a starting point to develop strategies that cover these parental needs.

Impact of prenatally diagnosed congenital heart defects on outcomes and management

Fetal echocardiogram aids in prenatal identification of neonates at high risk for congenital heart defects (CHD). Prenatal detection rates for CHD have increased with improved ultrasound technology, the use of the early fetal echocardiography, and standardization of the performance of the fetal echocardiogram. Accurate prenatal detection of CHD, particularly complex CHD, is an important contributor to improved survival rates for patients with CHD. Early detection allows for families to choose whether or not to continue with pregnancy, referral to pediatric cardiology specialists for patient education, and delivery planning. Better psychosocial supports are needed for families with CHD.

[Frecuencia de cardiopatías congénitas y adquiridas en 4,544 niños. Estudio basado en ecocardiografía]

Objetivo:

Mostrar la frecuencia de las cardiopatías congénitas y adquiridas en nuestra institución.

Material y métodos:

Se realizó un estudio retrospectivo, transversal y descriptivo donde se revisaron las libretas de los estudios ecocardiográficos, realizados en pacientes cuyas edades fueron de recién nacidos a 18 años y se agruparon por tipos de cardiopatías. En el análisis estadístico obtuvimos la frecuencia de ocurrencia, el valor de la proporción de cada cardiopatía.

Resultados:

En los últimos 10 años ingresaron 4,544 pacientes con cardiopatía. Las 14 cardiopatías más frecuentes correspondieron al 89.21% de la estadística. La cardiopatía más frecuente fue la persistencia del conducto arterioso con 896 pacientes (19%) y la cardiopatía adquirida más frecuente fue la miocardiopatía, con 116 pacientes (2.5%). La tetralogía de Fallot fue la cardiopatía cianógena más frecuente, con 139 pacientes (3%), a diferencia de otros países.

Conclusiones:

La frecuencia de cardiopatías congénitas y adquiridas es variable en diferentes áreas étnicas y geográficas.

Personalized Genetic Diagnosis of Congenital Heart Defects in Newborns

Congenital heart disease is a group of pathologies characterized by structural malformations of the heart or great vessels. These alterations occur during the embryonic period and are the most frequently observed severe congenital malformations, the main cause of neonatal mortality due to malformation, and the second most frequent congenital malformations overall after malformations of the central nervous system. The severity of different types of congenital heart disease varies depending on the combination of associated anatomical defects. The causes of these malformations are usually considered multifactorial, but genetic variants play a key role. Currently, use of high-throughput genetic technologies allows identification of pathogenic aneuploidies, deletions/duplications of large segments, as well as rare single nucleotide variants. The high incidence of congenital heart disease as well as the associated complications makes it necessary to establish a diagnosis as early as possible to adopt the most appropriate measures in a personalized approach. In this review, we provide an exhaustive update of the genetic bases of the most frequent congenital heart diseases as well as other syndromes associated with congenital heart defects, and how genetic data can be translated to clinical practice in a personalized approach.

[The adult with tetralogy of fallot: what the clinical cardiologist needs to know]

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. After more than seven decades of the first palliative surgery, TOF prognosis has changed dramatically. The prevalence of TOF is approximately 3 per 10 000 births, representing 7 to 10% of congenital heart disease. With a higher survival into adulthood, the clinical cardiologist faces challenges in the management of this population, from severe pulmonary regurgitation to heart failure and ventricular arrhythmias. Its prevalence is approximately 3 per 10 000 live births, representing 7 to 10% of congenital heart disease. This review will describe the most relevant aspects of the care of adult patients with this disease.

Tetralogy of Fallot in Spain: a nationwide registry-based mortality study across 36 years

Background

Tetralogy of Fallot (TOF) is the most frequent cyanotic congenital heart defect. TOF mortality has fallen remarkably in recent years due to therapeutic advances. Accordingly, the aim of this study was to assess temporal and spatial variability in TOF-related mortality in Spain across the period 1981–2016, using data drawn from the nationwide population-based registry.

Methods

Annual deaths due to TOF were sourced from the Spanish National Institute of Statistics database by reference to International Classification of Diseases (ICD), 9th and 10th Revision codes, namely, ICD-9 code 745.2 (period 1981–1998) and ICD-10 code Q21.3 (period 1999–2016). Age-specific and age-adjusted mortality rates were calculated, as were standardised mortality ratios (SMRs) by province, district and municipality for the period 1999–2016.

Results

A total of 1035 deaths were attributed to TOF (57.78% of them were men and 42.22% were women). The age-adjusted mortality rate ranged from 0.75 per 1,000,000 inhabitants (95% confidence interval [CI]: 0–1.36) in 1981 to 0.03 per 1,000,000 (95% CI: 0.01–0.06) in 2016 for both sexes. In 2011, there was a change in the mortality trend, with a significant decrease of 49.22% per year (p < 0.001). In terms of geographical analysis, some areas with a significantly higher risk of TOF mortality were identified in the south of Spain, though no specific spatial pattern was in evidence.

Conclusion

The decrease in TOF mortality may be related to improvements in diagnostic and treatment techniques. More studies are needed to analyse regions with a higher mortality risk, in order to improve medical planning and resource allocation, and identify risk factors and preventive measures.
