Fig. 2

Curved anatomical M-mode (CAMM). A4C view of the LV at end-diastole (left). The dashed line represents the curved M-mode cursor along the middle of the myocardium at end-diastole. The corresponding CAMM of the entire U-shaped LV is shown on the right. The top of the CAMM represents the medial annulus (septum) and the bottom is the lateral annulus. Abbreviations: CAMML ed and CAMML es the LV length at end-diastole and end-systole, MAPSE med and MAPSE lat MAPSE of the medial and lateral annuli. CAMML curved-anatomical M-mode length, MAPSE mitral annular plane systolic excursion
