Insights

This study details a rare "6-chambered heart" case, combining cor triatriatum sinistrum (CTS) and double-chambered right ventricle (DCRV). Successful surgical repair was achieved, highlighting the importance of accurate diagnosis for complex congenital heart defects.

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Pediatric Cardiac Surgery

Background:

  • Cor triatriatum involves atrial division by a membrane, creating three compartments.
  • Double-chambered right ventricle (DCRV) is characterized by an anomalous muscle bundle dividing the ventricle.

Purpose of the Study:

  • To describe an extremely rare case of combined cor triatriatum sinistrum (CTS) and DCRV.
  • To emphasize the implications of this combined anomaly on surgical repair.

Main Methods:

  • Case report of a pediatric patient with a complex congenital heart anomaly.
  • Description of successful intracardiac repair.

Main Results:

  • The patient presented with a unique "6-chambered heart" due to the coexistence of CTS and DCRV.
  • Successful surgical intervention was performed.

Conclusions:

  • The association of CTS with DCRV is exceptionally rare, creating a "6-chambered heart".
  • Accurate preoperative diagnosis is crucial for managing the complexities of surgical repair in such cases.

Chambers of the Heart01:16

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.
Deoxygenated blood from the body is received in the right...

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.

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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

Cardiomyopathy 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...

Overview of the Heart01:07

Overview of the Heart

The heart, a muscular organ located in the chest, functions as the body's pump, circulating blood through the vascular system. It has four chambers: two atria on top and two ventricles below. The right atrium receives deoxygenated blood from the body and passes it to the right ventricle, which pumps it to the lungs for oxygenation. The left atrium receives oxygenated blood from the lungs and transfers it to the left ventricle, which pumps it to the rest of the body.

Coronary Circulation01:21

Coronary Circulation

The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
