Insights

Criss-cross heart (CCH) is a rare congenital heart defect. This case highlights a unique CCH presentation with situs inversus totalis and bronchial dysplasia, emphasizing CT angiography

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Congenital Heart Disease

Background:

  • Criss-cross heart (CCH) is a rare congenital heart malformation.
  • CCH involves twisted atrioventricular connections and is often associated with other cardiac anomalies.
  • Accurate diagnosis of CCH can be challenging due to its complexity.

Purpose of the Study:

  • To report a previously undocumented case of CCH with complex associated malformations.
  • To illustrate the diagnostic utility of CT angiography in such complex cases.
  • To discuss the implications for surgical planning and treatment.

Main Methods:

  • Case presentation of a 10-year-old girl with recurrent cyanosis and fatigue.
  • Echocardiography identified CCH, dextrocardia, pulmonary hypertension, VSD, ASD, and PDA.
  • CT angiography revealed bronchial dysplasia and double-outlet right ventricle (DORV).

Main Results:

  • The patient presented with a rare combination of CCH, mirror dextrocardia, situs inversus totalis, and bronchial dysplasia.
  • CT angiography proved essential for a comprehensive assessment of the complex cardiac and non-cardiac anomalies.
  • The findings underscore the importance of advanced imaging in managing complex congenital heart disease.

Conclusions:

  • CCH is a rare condition with complex associated anomalies, posing diagnostic challenges.
  • CT angiography is crucial for detailed evaluation and surgical planning in CCH.
  • This unique case emphasizes the role of CT in guiding treatment for complex congenital heart defects, though further research on surgical strategies is needed.

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

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...

Location and Orientation of the Heart01:13

Location and Orientation of the Heart

The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

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.
