Case 20 — Two-Dimensional Echocardiograms

Right parasternal long-axis view at end-diastole during atrial systole. All four chambers visible (RA, RV, LA, LV). Mitral valve leaflets maximally open.
Right parasternal long-axis (end-diastole, atrial systole). Mitral valve leaflets maximally open. RA; RV; LA; LV.

Left apical view (end-diastole). Mitral valve leaflets at maximum excursion.
Right parasternal view of the aorta (Ao) and left atrium (LA). The LA body is moderately to severely enlarged. The left auricle (LAu) is also enlarged and projects cranially.
Basilar view. LA moderately to severely enlarged. LAu also enlarged, projecting cranially. Ao; RV.
