Abstract:
Left ventricular rotation is composed of systolic twist and diastolic untwist.The opposite motion of subendocardium and subepicardium,causing the left ventricular twist,fiurther leads to left ventricular systolic ejection.Then the left ventricular cardium in diastole rapidly retracts and releases the potential energy stored,which causes the early rapidly filling of left ventricle.Actually any physiological and pathologic changes that affect the state of the cardium can cause a change in left ventricular rotation.Also the left ventricular twist is determined and affected by the degree of myocardial contraction and relaxation,the preload and afterload,the balance of contraction between the subendocardium and subepicardium together with the myocardium orientation.The left ventricular untwist is influenced by the peak of left ventricular twist,left ventricular elastic energy,the myocardial relaxation characters and other factors,such as age and motition.In this paper,the research progress of left ventricular rotation is reviewed to promote its clinical application.
