Ventricular torsional relation to ventricular fiber arrangement

TL;DR

This paper explores the relationship between ventricular torsion and fiber arrangement in the heart, aiming to clarify the structural basis of the twisting motion observed during systole.

Contribution

It investigates the connection between ventricular fiber orientation and torsional deformation, providing insights into the structural mechanisms underlying cardiac motion.

Findings

Ventricular torsion is influenced by fiber orientation.

The study proposes a model linking fiber arrangement to twisting motion.

Results suggest structural basis for clinical observations of heart motion.

Abstract

Left ventricular torsion from helically oriented myofibers is a key parameter of cardiac performance. Physicians observing heart motion on echocardiograms, during cardiac catheterization, or in the operating room, are impressed by the twisting or rotary motion of the left ventricle during systole. Conceptually, the heart has been treated as a pressure chamber. The rotary or torsional deformation has been poorly understood by basic scientists and has lacked clinical relevance. The aim of this paper attempts to discuss about this question: Is ventricular twisting related to ventricular fiber arrangement? That is dependent to an assumed model of the left ventricular structure.
