Abstract

The mean circumferential contraction rate of the myocardial fiber cell (Mvcf) and the ejection fraction (EF) are echocardiographic parameters commonly employed in the assessment of left ventricular performance. In cases where septal asynchonism due to fibrosis or bundle-branch block make their determination impossible, however, one is forced to use parameters obtained from movement of the posterior wall. Investigation of normal subjects and patients with idiopathic hypertrophic subaortic stenosis showed that the "normalized" systolic velocity of the posterior wall (Vpws) and the non-normalized mean velocity (PWV) closely fitted Mvcf and that Vpws offered a good fit with EF. It is suggested that a non-invasive way of obtaining sufficiently reliable data for the evaluation of cardiac performance is offered by these two parameters.
