Figure Lengend Snippet: Left atrial volume measurement by 3D transthoracic echocardiography. Left atrial volumes (LAV) were measured by freehand 3D–transthoracic echocardiography using a dedicated software for left ventricular analysis (QLAB, 8.1, Philips Deutschland GmbH, Hamburg, Germany). Care was taken to manually adjust the measurement planes appropriately and exclude the pulmonary vein ostia and the left atrial appendage from the LAV at baseline, as well as at follow up controls after the procedure
Article Snippet: LA volumes were measured by freehand 3D echocardiography as described elsewhere [ ] using a software dedicated for left ventricular analysis (QLAB, version 8.1, Philips Deutschland GmbH, Hamburg, Germany), Fig. . LAA or the ostia of the pulmonary veins were excluded from the LA volume.
