Fig. 3From: Early detection of myocardial dysfunction in a cat that gradually progressed to endomyocardial form of restrictive cardiomyopathyLayer-specific two-dimensional speckle tracking echocardiography-derived left ventricular circumferential strain (LV-SC) curves at the level of papillary muscle on day 0 and day 468. The left curves represent the endocardial layer, the middle represent the whole layer, and the right represent epicardial layer. Only endocardial LV-SC at the level of papillary muscle on day 0 has already been below the normal range which established from 15 healthy cats, and that of the whole and epicardial layers were additionally decreased on day 468Back to article page
