The understanding of congenital heart diseases from a segmental viewpoint

Segmental imaging is a well-known method of diagnosing the presence of congenital heart diseases. It involves three steps of evaluation of the anatomy of the heart. The position of the visceroatrial is assessed by.


Step 1. Visceroatrial positions refer to the relative location between the atria and the anatomy surrounding it (including the liver, stomach as well as stomach). There three possible anatomic arrangements for this: situs solius as well as situs inversus and the ambiguous.

The second step is to determine the right or left direction of the ventricular loop. In light of their internal morphologic features the ventricles' locations can be determined. Step 3 determines where great vessels are located , and any abnormalities are identified.


Abnormalities in the origin of the great vessels, or conotruncal anomalies, are predominantly of three types: D-transposition (dextrotransposition), L-transposition (levotransposition), and D-malposition with double outlet right ventricle. The relationship between the atria , ventricles along with the vast vessels can be assessed on two different levels. The Atrioventricular (concordant or dicordant, with an unclear dual input or absence of of right or left connections) as well as the ventriculoarterial (concordant and discordant double outlets).

The final step is to check for any signs of abnormalities within the major vessels the cardiac chambers septa, outflow tract , and the cardiac chambers. Radiologists can more accurately interpret the image when they follow the correct sequence of steps in image review. Reconstructions that are multiplanar of cross-sectional pictures taken from magnetic resonance imaging as well as computed tomography can be particularly beneficial for patients with congenital heart disease.

Once you've completed the article and completed this test successfully, you is feasible to:


  • The steps that are involved during the procedure to assessing the risk of developing congenital heart diseases.
  • The three types of visceroatrial scenarios.
  • Find the most significant abnormalities in the development of the heart that can lead to the development of congenital heart diseases.


Introduction

Radiologists are now looking into Multidetector Computed Angiogram (CT) as well as cardiac magnetic resonance imaging(MR) to diagnose the presence of congenital heart diseases. This has led to a review by cardiologists and cardiac surgeons regarding the classification and definitions that are used to determine the severity of the disease. Segmental analysis of congenital heart disease was first introduced to the public for the first time in 25 years ago. It is still widely used. It is easy to use, and versatile enough for anyone who is not an expert. The method is compatible in conjunction with any imaging method which makes it especially useful in the clinical setting. This article will review Van Praagh's basic theories and then discuss the ways they've been implemented in various clinical settings across Europe and the United States.


examines the anatomy of the heart through the first break-down of it down into three parts. They are based upon the 10 embryologic areas A Segmental Approach.


These segments form the fundamental components of the cardiac anatomy. Each segment's anatomical and morphologic characteristics are evaluated independently. The ventriculoarterial and Atrioventricular levels are utilized to evaluate the connections between segments. Additionally, any abnormalities that are related to specific segments are reviewed. This is a good way to combine Van Praagh's system of notation that is composed of three letters that are separated by the parentheses.



What is your Visceroatrial Situations


There are three kinds of locations: solitus, inversus, Inversus and unclear. The kind of situation can be determined by the relation between the atria as well as adjacent organs. Every patient has the ability to only be diagnosed with one kind of disorder. The first step in assessing the anatomy of the heart is to identify and locate the arterioles of the left and right. Anatomy of the chamber atrial is determined by the morphological characteristics of the appendages to the atrial. The Atria may be thought of as atrial appendages being extensions of the ears. The right atrial appendage is triangular and tends to be wide and sharp. Left atrials are narrow small, pointed with a tubular (fingerlike) However, it's typically narrower as well as more pointed and more tubular. Radiologic imaging may cause difficulty in locating appendages. Organs that are not cardiac are more easily located than appendages.


A sign of the arrangement of the atrial can be seen in the anatomy of the bronchial (or the pulmonary) at the thoracic. This is the relation between the main left and right main bronchisas well as the pulmonary vessels.


It is vital to know the position of the liver and stomach on the stomach level. This rule Venoatrial Concordance (IVC) is a reference point that helps you locate the anatomical rights of your atrium.


The position of the heart inside the chest, as well as the an orientation of the cardiac alpex could all affect the condition. It's not required. The factors mentioned above could be used to determine the likelihood for congenital heart diseases (Table). Based on your cardiac base-apex orientation, there are three types de cardiac malpositions: mesocardia or dixrocardia, mesocardia/levocardia and mesocardia/levocardia.


Levoposition refers to the location of the heart inside the chest cavity. Dextroposition refers specifically to the position in the left chest. Mesoposition is the midline position. The base-apex may be tilted towards the right chest area in all three instances. Dextrocardia can occur in the event that your heart lies located in the left chest, with the base-apex axis tilted to the right. The cause of Dextrocardia is any circumstance.


It is a common rule that situs and cardiac anomalies are more common when the location of the heart or stomach is in agreement. They also occur less frequently in the event that one of these landmarks are in discordant positions (Fig. 1). It is essential to identify any pulmonary or thoracic abnormalities that could lead to your heart being moved. Hypoplastic right lung may result in dextroposition or left-sided arpeggio. This is the reason congenital heart disease is not as likely.
