.

LA volume was estimated by the area-length method. LA area and length were measured at end-systole in apical 4- and 2-chamber views, excluding the atrial appendage and pulmonary veins. LA volume was calculated using the formula (A1×A2/L)×8/3π, where A1 and A2 are the LA areas from 4- and 2-chamber views, respectively, and L is the shorter of the two long-axis lengths

.

normal LA size was defined as LAVI ≤34 ml/m2, mild dilatation as 35-41 ml/m2, moderate dilatation as 42-48 ml/m2 and severe dilatation as >48 ml/m2.

.

However, in this study only moderate and severe LA enlargement and age >75 years were predictors of all-cause mortality and only severe LA enlargement, moderate-to-severe LV systolic dysfunction, LV hypertrophy and moderate mitral regurgitation were independent predictors of both composite endpoints.

Átrios acima de 28 ml/m2 e abaixo de 34 ml/m2 são normais?

.

Provavelmente não.

Mas para capturar o impacto na sobrevida seria necessário um número maior de pacientes e de tempo de acompanhamento.
