Chronic aortic valve disease can result in distinct adaptive left ventricular (LV) geometric patterns, which has different effects on LV function and left atrial (LA) performance. In this study we assessed the effect of LV geometry on LA size and function, and we verified the relation between LA size and LV mass in patients with distinct LV overload subsets. We analyzed 183 patients with aortic valve disease who underwent a complete echocardiographic evaluation. Based on the type of valvular dysfunction, patients were classified into 2 groups: 141 patients with aortic stenosis (group AS) and 42 patients with pure aortic regurgitation (group AR). Each of these 2 groups were then divided into those with a concentric LV pattern and those with an eccentric pattern. Both LA size and LA ejection force were significantly greater in group AS than group AR, particularly in patients with a concentric LV pattern. The degree of LA enlargement depended on LV mass in the patients with a concentric LV pattern (group AS r = 0.61, p <0.00001; group AR r = 0.38, p = 0.04). In contrast, no relation was found between LA size and LV mass in the patients with an eccentric pattern, independently of the type of valve dysfunction. Our results indicate that the influence of LV geometry on LA size and function in patients with aortic valve disease is relevant. A concentric LV pattern is associated with greater LA size and higher ejection than an eccentric pattern, suggesting that chronic LV pressure overload more than volume overload has a greater effect on stimulating increases in LA performance. The degree of LA enlargement depends on LV mass in patients with a concentric LV pattern, whereas it was unpredictable in those with an eccentric LV pattern. |
