TI  - Left atrial and left atrial appendage function in paroxysmal atrial fibrillation.

AB  - PURPOSE: In patients with paroxysmal atrial fibrillation (PAF) little information 
      is available about left atrial (LA)function, and there is less information about 
      LA appendage (LAA) function, and about their relations. METHODS AND RESULTS: 46 
      patients were selected for catheter ablation (CA) because of nonvalvular 
      PAF.Transthoracic, tissue Doppler and transoesophageal echocardiography was 
      performed before CA. LA volumes and volume index (LAVI) were calculated. LA 
      function was assessed by LA filling fraction (LAFF), LA emptying fraction (LAEF), 
      systolic fraction of pulmonary venous flow (PVSF) and late diastolic velocities 
      of mitral annulus(Aa,, A5at) LAA function was assessed by peak LAA emptying flow 
      velocity (PLAAEFV). Diastolic dysfunction(DD) was also assessed. Dilated LAVI in 
      32, LA dysfunction in 20, DD with elevated LV filling pressure in 19 patients was 
      found. Aa,at and Aa,p correlated with LAFF (r:0.53; p<0.001 and r:0.43; p<0.05), 
      LAEF (r:0.51;p<0.001 and r:0.63; p<0.001), PVSF (r:0.49; p<0.001 and r:0.46; 
      p<0.005) and PLAAEFV (r:0.58; p<0.001 and r:0.45; p<0.01). CONCLUSIONS: In PAF 
      patients Aa velocity is useful to assess LA function and correlates positively 
      with other TTE derived LA functional parameters and LAA function by TEE derived 
      PLAAEFV.
