The wall has a well-ordered distribution of fiber angles varying from about 60° (from the circumferential direction) at the inner surface to about –60° on the outer surface, and the greatest change in angle occurs at the two surfaces (endocardial and epicardial).

The patient with an implanted cardiac device can safely undergo surgery as long as certain precautions are taken and the use of magnetic resonance imaging is avoided in this population of patients.

The present results indicate that the normal left ventricle functions along the ascending portion of the length-tension curve, where the end diastolic sarcomere lengths are 2.2 μ or less.

- 1 October 1967
The relations between ultrastructure and function have been examined in the canine left ventricle under known hemodynamic conditions and the importance of dispersion of sarcomere length within a given layer of the ventricular wall was noted and its potential significance discussed.
Left ventricular form and function: scientific priorities and strategic planning for development of new views of disease.
