Dilated aorta changed the LA geometry leading to irregular elongated shape of the chamber. Dilated aortic root also caused deformation of mitral annulus and mild mitral regurgitation. LA maximum volume was normal when measured by both biplane 2D echocardiographic methods (discs’ summation and area length).
Final result of the 3D echocardiographic volumetric analysis of the LA. 3D quantitation of the LA maximum volume allowed to reclassify the patient as having mildly enlarged LA and diagnose (together with E/E’=14,4) LV diastolic dysfunction.
