“…To the best of our knowledge, this is the first paper in which critically ill patients were evaluated with RT-3D in order to study LA volumes and function: our results demonstrated that this technique reached a very good clinical applicability. We observed a very good correlation between measurements derived from 2D and RT-3D images, especially for LA volumes: previous papers that evaluated this topic demonstrated a good correlation between the two measurements, with a slight underestimation by 2D in presence of LA dilation (23). For LA EF value, correlation was slightly worse compared with volume measurements: data on reproducibility of LA EF between 2D and 3D are actually lacking, so that further studies are needed to confirm our finding.…”

“…LA volume measured using echocardiography is smaller than that measured using cardiac CT by approximately 30-40 mL (25-30% of the total volume) [36]. The recently introduced real-time, three-dimensional (3D) echocardiography may overcome the limitation of 2D echocardiography [37].…”

“…A ecocardiografia tridimensional em tempo real (E3DTR) é uma modalidade de imagem mais recente, não invasiva, que permite medir diretamente os volumes do AE ao longo de todo o ciclo cardíaco, sem a necessidade de modelos geométricos, com excelente resolução temporal 37 . Permite avaliar, com alta acurácia, o volume e a função do AE, e já foi estudada, com essa finalidade, em diversas situações clínicas [38][39][40] .…”

“…Algumas evidências de alterações da função atrial esquerda ou da sua rigidez em pacientes com insuficiência cardíaca representam um alento nesse tipo de avaliação 38,39,50,51 . Nesse cenário, por meio da ecocardiografia bidimensional, demonstrou-se que a capacidade física dos pacientes com miocardiopatia dilatada idiopática está diretamente relacionada à fração de esvaziamento do AE 52 .…”
