Raccomandazioni ASE-EAE ……..AP linear dimensions of the LA as the sole measure of LA size may be misleading and should be accompanied by LA volume determination in both clinical practice and research. …… when LA size is measured in clinical practice, volume determinations are preferred over linear dimensions because they allow accurate assessment of the asymmetric remodeling of the LA chamber.

Il volume atriale sinistro meglio riflette, rispetto ad altri indici, la severità della disfunzione diastolica e la prolungata esposizione della camera atriale ad un alterata funzione diastolica ed elevate pressioni di riempimento e come la disfunzione diastolica ha un forte legame con la prognosi.

La dilatazione dell’atrio sin. comporta importanti implicazioni cliniche e prognostiche. La determinazione del volume è superiore al diametro AP come misura delle dimensioni atriali. Le attuali lineeguida sconsigliano la determinazione con misura lineare. La determinazione del volume aggiunge informazioni che hanno importante valore prognostico aggiuntivo ed indipendente da altri fattori. La valutazione del volume dovrebbe essere quindi inserita nella valutazione ecocardiografica di routine. Conclusioni
