Abstract:
Objective The aim of this study is to address learning curve and clinical outcomes of totally robotic atrial septal defect repair on the basis of a single - center experience.Methods 54 cases of atrial septal defect (ASD) were repaired using “da Vinic S surgical system on arrested ( group Ⅰ,54 cases) or beating heart ( group Ⅱ,40 cases) from January 2007 to December 2010.Learning curves were assessed by means of regression analysis with logarithmic curve fit.The effect of operative variables on clinical outcome was analyzed by linear by regression using the Spearman's rho coefficient.Results All cases were accomplished successfully without complications.No residual shunt was detected at intraoperative or postoperative echocardiography.Significant learning curves were noted for corss clamp time in group Ⅰ:y (min) =68.741 -8.283 (n) (x)( r2 =0.489 ; P ＜ 0.01 ) ; the operation time in group Ⅱ:y (min) =355.51 - 56.29 (n) (x) ( r2 =0.581 ; P ＜ 0.01 ).No correlation was detected between operation time,cardiopulmonary bypass time,or cross clamp time and intubation time,intensive care unit stay,or total length of stay.Conclusion The robotic atrial septal defect repair can be performed safely.The learning curves is steep and the longer cardiopulmonary bypass times,operation time or cross clamp time had no negative impact on intraoperative and postoperative outcome.
