Area of Science:

  • Cardiovascular Morphology
  • Congenital Heart Disease
  • Anatomical Description

Background:

  • Lack of consensus exists on describing complex congenital heart malformations.
  • Current methods include segmental combinations or descriptive approaches.
  • A standardized descriptive system is needed for clarity.

Purpose of the Study:

  • To propose a simple, descriptive method for classifying complex congenital heart malformations.
  • To demonstrate the utility of this descriptive approach in anatomical assessment.
  • To establish a reliable method for predicting conduction tissue location.

Main Methods:

  • Review of personal experience examining congenitally malformed hearts.
  • Identification of constant anatomical components: atrial appendages, ventricular apical trabecular regions, and arterial trunk branching patterns.

  • Description based on the connections between chambers and trunks, with separate accounting for additional features.

    • Main Results:

    • A consistent method was developed to define atrial and ventricular chamber morphology and arterial trunks.
    • All hearts could be described based on the interconnections of these defined components.
    • Additional morphologic features and abnormal relationships were systematically described.

    Conclusions:

    • A simple descriptive approach effectively characterizes complex congenital heart malformations.
    • This method does not rely on developmental concepts.
    • It enables accurate basic descriptions and prediction of conduction tissue location in novel cases.
