   atrial contraction % (n) 87.8 (79) 100 (12) 0.200
   E/A ratio   2.5 ± 0.83 2.1 ± 0.75 0.179
atrial fibrillation % (n) 26.3 (39) 11.8 (2) 0.187
atrial flutter % (n) 3.4 (5) 5.9 (1) 0.601
NYHA class   1.9 ± 0.61* 2.1 ± 0.57* 0.304
LA diameter mm 42 ± 6.3* 42 ± 9.1* 0.952
LVEF   0.52 ± 0.120 0.55 ± 0.091* 0.358
LVEDD mm 54 ± 9.4 49 ± 8.3 0.048
  1. *p < 0.001, comparison to preoperative data by Wilcoxon rank-sum test
  2. p = n.s., comparison to preoperative data by Wilcoxon rank-sum test
  3. E/A ratio, ratio of maximal flow velocities of early (E) and atrial (A) diastolic transmitral flow signal assessed by pulsed-wave Doppler; NYHA, New York Heart Association; LA, left atrial; LVEF, left ventricular ejection fraction; LVEDD, left ventricular enddiastolic diameter
  4. Assessment of LA function by pulsed wave Doppler failed in 11 and 2 patients in the younger and older age group, respectively.
