Use of the three-dimensional technique to remove the looking glass through which the echocardiographers have imagined the pathophysiology of atrioventricular valve regurgitation

This editorial refers to ‘Differences in mitral valve geometry between atrial and ventricular functional mitral regurgitation in patients with atrial fibrillation: a three-dimensional transesoèhageal echocardiography study’ by G. Uno et al., pp. 1106--16. Historically, echocardiography has always represented the mainstay of assessing the pathophysiology of atrioventricular valve diseases, their severity, and the extent of their impact on the up-...
