Summary
Isolated double-chambered right ventricle (DCRV) is rare, often diagnosed in adolescence. Surgical resection of anomalous muscle bundles is effective, with intraoperative transesophageal echocardiography aiding successful outcomes.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Double-chambered right ventricle (DCRV) is a congenital anomaly characterized by anomalous muscle bundles dividing the right ventricular cavity.
- It is frequently associated with other cardiac defects, most commonly ventricular septal defects.
- Isolated DCRV, without other defects, is exceptionally rare and typically presents in adolescence or adulthood due to gradual obstruction progression.
Observation:
- A 13-year-old male presented with symptoms indicative of an isolated DCRV.
- The patient had an intact interventricular septum, highlighting the rarity of this presentation.
- The condition was managed surgically.
Findings:
- Successful surgical resection of the anomalous muscle bundles within the right ventricle was performed.
- Transesophageal echocardiography proved invaluable intraoperatively.
- This imaging modality accurately identified the anomalous muscle bundles and confirmed the completeness of the resection.
Implications:
- Early recognition and intervention for isolated DCRV are crucial to prevent progression to severe right ventricular failure.
- Surgical management, including muscle bundle resection, offers a viable treatment option.
- Intraoperative transesophageal echocardiography enhances surgical precision and improves patient outcomes in DCRV cases.

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.

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.

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.

3.2K
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...

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...

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...
