Resumen
Una nueva técnica de inserción de bobina detuvo con éxito el flujo sanguíneo a un gemelo cardíaco, protegiendo al gemelo sano de la tensión cardíaca. El gemelo sano nació a término con un resultado neonatal normal.
Área de la Ciencia:
- Perinatología Perinatología.
- La medicina materno-fetal es una de ellas.
- Cardiología Intervencionista Cardiología intervencionista.
Sus antecedentes:
- La malformación del gemelo cardíaco plantea riesgos significativos para el gemelo sano debido al aumento de la carga de trabajo cardíaca.
- Las intervenciones quirúrgicas existentes para gemelos cardíacos pueden conllevar riesgos maternos sustanciales.
Objetivo del estudio:
- Para describir una técnica novedosa y mínimamente invasiva para el tratamiento de la malformación gemela acárdica acepálica.
- Evaluar la eficacia de la inducción de la trombosis de la arteria umbilical en el gemelo acárdico para proteger al co-gemelo.
Principales métodos:
- Se insertó una bobina de metal helicoidal en la arteria umbilical del gemelo acárdico.
- La bobina fue diseñada para inducir la trombosis e interrumpir inmediatamente el flujo sanguíneo.
Principales resultados:
- El flujo de la arteria umbilical al gemelo acárdico se interrumpió inmediatamente después del procedimiento.
- El gemelo sano nació a las 39 semanas de gestación.
- El recién nacido exhibió un curso clínico normal.
Conclusiones:
- La trombosis de la arteria umbilical inducida por la bobina es un método seguro y eficaz para el manejo de la malformación gemela acárdica acepálica.
- Esta técnica mitiga los riesgos asociados con la circulación anormal y mejora los resultados de co-gemelos.
- Ofrece una alternativa potencialmente menos peligrosa a los métodos quirúrgicos tradicionales.

01:16Chambers 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.

01:16Heart 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...

01:26Imbalances in Cardiac Output
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send blood...

01:27Development of the Heart
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart tube by...

01:07Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
