Summary
This study showcases cardiac magnetic resonance imaging of a child with a complex congenital heart defect. The findings highlight an unusual arrangement of the great arteries in a pediatric patient.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease Imaging
- Cardiac Magnetic Resonance
Background:
- Mesocardia is a rare condition where the heart is located centrally in the chest.
- Atrial situs solitus refers to the normal left-right arrangement of the atria.
- D-looping of the ventricles indicates the typical orientation of the ventricular mass.
Observation:
- The patient, a 6-year-old, presented with suspected great artery abnormality.
- Cardiac magnetic resonance imaging (CMR) was utilized for detailed anatomical assessment.
- The imaging revealed mesocardia with atrial situs solitus and D-looping of the ventricles.
Findings:
- Anatomically corrected malposition of the great arteries (ACM) was diagnosed.
- The condition involved both subaortic and subpulmonary conus.
- This specific complex cardiac malformation was visualized using CMR.
Implications:
- Accurate diagnosis of complex congenital heart disease is crucial for pediatric cardiac care.
- Cardiac MRI provides detailed anatomical information for surgical planning.
- Understanding these rare great artery anomalies aids in improving patient outcomes.

01:11Anatomical Positions
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
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...

01:27Anatomy 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.
