Postoperative outcome and early survival. Comparison of biatrial (n = 37), bicaval (n = 191) and modified bicaval (n = 10) anastomoses technique. Results are presented as mean values with the standard deviation respectively percentages of the whole. † Post-hoc analysis of sinus rhythm at discharge: biatrial vs. bicaval: p = 0.01, biatrial vs. modified bicaval: p = 0.31, bicaval vs. modified bicaval: p > 0.99. †† Post-hoc analysis of implanted pacemakers at discharge: biatrial vs. bicaval: p = 0.004, biatrial vs. modified bicaval: p = 0.31, bicaval vs. modified bicaval: p > 0.99. ††† Post-hoc analysis of implanted pacemakers at last follow-up visit: biatrial vs. bicaval: p = 0.01, biatrial vs. modified bicaval: p = 0.31, bicaval vs. modified bicaval: p > 0.99.
