Popis: The rate of progression of the degree of chronic aortic regurgitation (AR) is unknown. Furthermore, although left ventricular (LV) dilation has been studied in patients with severe AR, its rate and determining factors, and specifically, its relation to the degree of regurgitation remain to be established and have not previously been studied for mild and moderate AR. The purpose of this study was to explore the progression of chronic AR by 2-dimensional and Doppler echocardiography, and the relation of LV dilation to the fundamental regurgitant lesion and its progression in patients with a full spectrum of initial AR severity. We studied 127 patients with AR by 2-dimensional and Doppler echocardiography (69 men; 59 +/- 21 years; 67 with mild, 45 with moderate, 15 with severe AR). AR increased in 38 patients (30%) (25% of mild, 44% of moderate, and 50% of moderate to severe lesions; p
