    Insights

    Double outlet right ventricle (DORV) exhibits diverse anatomical variations. This study proposes a classification based on great vessel relationships and ventricular septal defects, emphasizing detailed individual case descriptions due to DORV

    Area of Science:

    • Cardiovascular Anatomy
    • Congenital Heart Disease Research
    • Pathology

    Context:

    • Double outlet right ventricle (DORV) is a complex congenital heart defect.
    • Understanding DORV's anatomical spectrum is crucial for diagnosis and treatment.
    • Previous classifications may not fully capture DORV's heterogeneity.

    Purpose:

    • To define and classify anatomical variations of double outlet right ventricle (DORV).
    • To analyze the relationship between great vessels and ventricular septal defects in DORV.
    • To correlate autopsy findings with clinical data (angiographic and surgical).

    Summary:

    • Reviewed 64 autopsy cases of DORV, defining it as the origin of trunco-conal structures from the right ventricle.
    • Identified diverse anatomical variations, including normally crossed, transposed, and side-by-side great arteries, and common truncus.
    • Proposed a classification based on great vessel arrangement and ventricular septal defect presence/type, noting anterior VSDs in specific subtypes.

    Impact:

    • Highlights the significant heterogeneity of DORV, necessitating detailed individual anatomical assessment.
    • Provides a framework for classifying DORV based on key anatomical features.
    • Informs diagnostic strategies and surgical planning for patients with DORV.

    Anatomy of the Circulatory System02:03

    Anatomy of the Circulatory System

    The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.
    Anatomy of the Heart01:27

    Anatomy of the Heart

    The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

    Anatomy of the Brain: Ventricles

    There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...

    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.

    Development of the Heart01:27

    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...

    Anatomy of the Heart

    The heart is a hollow, muscular organ approximately the size of a fist, consisting of four chambers. It is enclosed in the pericardium, a fibrous sac with two layers: the visceral and parietal pericardium, separated by a fluid-filled space containing serous fluid to reduce friction.
    The heart has three layers: the innermost endocardium, the muscular myocardium, and the outer epicardium, all working together for optimal cardiac function.
