|March 4, 1997
Resumen
Este estudio identifica un tipo único de defecto septal ventricular apical (VSD) con características anatómicas distintas. Estos VSDs ventriculares-infundibulares izquierdos se pueden diagnosticar utilizando imágenes y tratar con dispositivos transcatéter.
Área de la Ciencia:
- Cardiología Cardiología.
- Cardiología Pediátrica Cardiología pediátrica.
- Cirugía cardíaca Cirugía cardíaca.
Sus antecedentes:
- Los defectos del tabique ventricular muscular apical (VSD) presentan una anatomía compleja que desafía el cierre efectivo.
- La comprensión tradicional ve las VSD como simples comunicaciones entre los vértices ventriculares.
Objetivo del estudio:
- Para caracterizar un tipo morfológico distinto de VSD muscular apical.
- Para evaluar el diagnóstico por imágenes y el cierre transcatéter de estos defectos únicos.
Principales métodos:
- Análisis retrospectivo de 50 pacientes con SDV musculares sometidos al cierre del dispositivo transcatéter.
- Evaluación anatómica detallada mediante ecocardiografía y cineangiografía.
- Evaluación de la colocación del dispositivo transcatéter y los resultados clínicos.
Principales resultados:
- Diez pacientes exhibieron un VSD apical único con aberturas ventriculares izquierda y derecha específicas y separando haces de músculo.
- Los dispositivos transcatéter se colocaron con éxito en 9 pacientes, incorporando el ápice infundibular en el ventrículo izquierdo.
- La ecocardiografía identificó este tipo distinto de SDV en 20 de 274 pacientes con SDV musculares.
Conclusiones:
- Las VSDs apicas ventricular-infundibulares izquierdas representan una entidad morfológica distinta.
- La ecocardiografía y la cineangiografía son cruciales para diagnosticar estos defectos.
- El cierre del transcatéter es efectivo en casos seleccionados, separando el ápice infundibular para ocultar el defecto.

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...

Development 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...

Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
Cardiac Catheterization III: Left Heart Catheterization
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
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...
