Long axis function in disease

MHM. Y HENEINDGDerek G. Gibson

Key Result

Loss of longitudinal fibre function leads to characteristic disturbances in normal ejection fraction and atrioventricular interactions.

Key Points

  • The aim is to explore the significance of longitudinally directed fibres in cardiac function and disease.
  • Focus on the structural roles of longitudinal fibres in the left and right ventricles.
  • Examine how these fibres contribute to ejection fraction and atrioventricular interactions.
  • Loss of longitudinal fibre function disrupts normal ejection fraction.
  • Disturbances in cardiac function are correlated with diminished fibre function.

Loss of longitudinal fibre function

Abstract

Although longitudinally directed fibres-situated mainly in the subepicardium and subendocardium regions of the left and right ventricular free walls and the papillary musclescomprise only a small proportion of the total ventricular myocardial mass, they play a major role in the maintenance of normal ejection fraction and in determining atrioventricular interactions. 1 Not surprisingly, therefore, loss of longitudinal fibre function leads to characteristic disturbances.
