Usefulness of Echocardiographic Peak Velocity of Circumferential Fibre Shortening

Echocardiography has been recommended as a valuable non-invasive technique for the assessment of left ventricular function. The motion of the endocardial surfaces of the septum and posterior wall can be recorded by directing the ultrasound beam just inferior to the mitral valve plane. From this the left ventricular minor axis diameter can be accurately measured throughout systole and the stroke volume, ejection fraction, posterior wall velocity and mean velocity of circumferential fibre shortening (mean VCF) can be estimated.
