Insights

This case study describes a rare crisscross heart in an adult woman with an intact ventricular septum. This finding highlights the varied presentations of this congenital heart anomaly.

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Cardiac Imaging

Background:

  • Crisscross heart is a rare congenital anomaly defined by a twisted atrioventricular connection due to ventricular mass rotation.
  • Typical presentations involve complex cardiac malformations and may manifest in infancy or childhood.

Purpose of the Study:

  • To report a unique case of asymptomatic adult-onset crisscross heart.
  • To highlight the presentation of crisscross heart with an intact ventricular septum.

Main Methods:

  • Clinical evaluation of a 48-year-old woman presenting with a cardiac murmur.
  • Echocardiography and other cardiac imaging modalities to assess cardiac anatomy and connections.

Main Results:

  • Diagnosis of situs solitus with dextrocardia and a crisscross relationship of atrioventricular valves.
  • Absence of ventricular septal defect, distinguishing it from typical crisscross heart cases.
  • Patient remained asymptomatic despite the cardiac anomaly.

Conclusions:

  • Crisscross heart can present asymptomatically in adulthood, even with an intact ventricular septum.
  • This case expands the spectrum of clinical and anatomical variations of crisscross heart.
  • Further investigation into rare congenital heart diseases is warranted.

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.

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 II: Dilated Cardiomyopathy01:30

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

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...

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...
