Abstract
Left ventricular torsion: feeling the heat
Highlights
The term ‘left ventricle (LV) twist mechanics’ encompasses both systolic LV torsion (LVT) and diastolic untwisting rate (UTR) and is an important contributor to overall LV function
When viewed from an apical reference point, systolic rotation at the apex is anticlockwise while the base rotates in an overall clockwise direction. This counterdirectional rotation results in a wringing motion of the heart, known as left ventricle (LV) torsion (LVT) or twist
It is noteworthy that the increased LVT seen with heat stress at rest was secondary to an increase in basal rotation
Summary
The term ‘LV twist mechanics’ encompasses both systolic LVT and diastolic UTR and is an important contributor to overall LV function. Both measurement technique and physiological factors are determinants of observed LVT. Physiological determinants of LVT include but are not limited to cardiac loading conditions, myocardial contractility, structural heart disease, heart rate, age and exercise training.
