Background The left atrial appendage （LAA） is an important source of thrombus formation. We investigated the feasibility of the recently developed real-time three-dimensional transesophageal echocardiography （RT3D-tee） method in assessment of the morphology and function of the LAA. Methods Ninety-six consecutive patients （58 males with a mean age of （43.4±12.5） years） who were referred for 2-dimensional （2D） transesophageal echocardiography （tee） underwent additional RT3D-tee. LAA morphology was visualized in multiple views. Orifice size, depth, volumes and ejection fraction （EF） of the LAA, were measured. Results All the patients underwent RT3D-tee examination without complications. Ninety-two patients （95.8%） had adequate images for visualization and quantitative analysis of the LAA. The LAA exhibited great variability with respect to relative dimensions and morphology. LAA orifice area was （3.8±1.2） cm^2 with a diameter of （2.4±0.9） cm x （1.4±0.6） cm. The mean depth of the LAA was （2.9±0.7） cm. End-diastolic volume （EDV-LAA）, end-systolic volume （ESV-LAA） and EF of the LAA were （6.2±3.7） ml, （4.1±2.8） ml, and 0.35±0.16, respectively. EDV-LAA, ESV-LAA and the orifice area of the LAA in patients with atrial fibrillation （AF） were larger than those without AF, whereas the EF was smaller in the AF patients. conclusions Defining LAA morphology and quantitative analysis of the size and function of the LAA with superior quality and resolution of images using RT3D-tee is feasible. This technique may be an ideal tool for guidance of the LAA occlusion procedure. Determination of LAA volumes and volume-derived EF by RT3D-tee provides new insights into the analysis of LAA function.

Methods: Sixteen patients with American Society of Anesthesiologists status (ASA) II-III, age ≤ 70 yr, male or female, preoperatively NYHA II-III and EF ≥ 45%, scheduled for mitral valve replacement (MVR) were studied. complete intravenous general anesthesia was used for induction and anesthesia maintenance. After anesthesia induction we put the tee probe into the esophagus. The cardiac index was determined at three periods following MVR: T1 30 minutes later following cessation of bypass, T2 60 minutes after cessation of bypass, T3 90 minutes after cessation of bypass. Statistical analysis was made with the Bland and Altman method. Results: Ninety-six measurements were compared. The cardiac index values at the level of prosthesis mitral valve (cIMV) ranged from 1.3 to 5.5 L·min-1·m-2 (mean 2.6 ± 0.9). The Values of cardiac index at aortic valve (cIAA) ranged from 2.7 to8.8 L·min-1·m-2 (mean 4.9 ± 1.7). Bias was -2.3 L·min-1·m-2 and limits of agreement -5.6 to 1.0 L·min-1·m-2. conclusion: During mitral valve replacement, doubtful correlations were observed between values of cardiac index at the mitral valve and the ascending aorta using tee.
