¿Hay una epidemia de defectos del tabique ventricular en los EE.UU.?
Lancet (London, England)
|February 23, 1980
Resumen
La incidencia del defecto septal ventricular (VSD) ha aumentado, pero el diagnóstico mejorado no es la causa. Un estudio encontró tasas de cierre espontáneo similares para VSDs, lo que indica que otros factores están en juego.
Área de la Ciencia:
- Cardiología Pediátrica Cardiología pediátrica.
- Vigilancia de la salud pública.
- Defectos congénitos del corazón.
Sus antecedentes:
- La incidencia reportada de defecto septal ventricular (VSD) se ha más que duplicado en los últimos años.
- Este aumento se ha observado en los principales sistemas estadounidenses de vigilancia de defectos de nacimiento.
Objetivo del estudio:
- Investigar si la mejora del diagnóstico clínico, en particular de las SDV menores, explica el aumento de la incidencia.
- Para comparar las tasas de cierre espontáneo de VSDs diagnosticados en diferentes períodos de tiempo.
Principales métodos:
- Un estudio de seguimiento de bebés diagnosticados con SDV en el área de Atlanta.
- Comparación de las tasas de cierre espontáneo de VSD a 1 año de edad entre bebés diagnosticados en 1970-1972 y 1975-1976.
Principales resultados:
- La tasa de cierre espontáneo de VSD a los 1 años de edad fue casi idéntica entre los dos períodos de diagnóstico (23,8% frente a 23,9%).
- Este hallazgo sugiere que el diagnóstico mejorado de SDV menores que se resuelven espontáneamente no explica el aumento observado en la incidencia.
Conclusiones:
- El aumento significativo en la incidencia reportada de defecto del tabique ventricular no es únicamente atribuible a las capacidades de diagnóstico mejoradas.
- Se necesita más investigación para identificar las razones subyacentes de la creciente incidencia de VSD.

Chambers of the Heart
The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

Heart Valves
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
Mitral Stenosis II: Clinical features and Diagnostic Tests
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
Pulmonary Edema II: Pathophysiology
Pulmonary edema is the accumulation of fluid in the interstitial and alveolar spaces of the lungs, impairing gas exchange and oxygen delivery. It may be cardiogenic or noncardiogenic, but both reduce oxygenation and lung compliance.Cardiogenic Pulmonary EdemaCardiogenic edema results from increased hydrostatic pressure in pulmonary capillaries, usually due to left ventricular dysfunction from myocardial infarction, heart failure, or valvular disease. Ineffective cardiac pumping causes blood to...
