Can any conclusion be justified with a 27% loss of patients at follow-up? Reply

To the Editor:

We were somewhat suprised by the critical remarks posed by Dr Corno regarding our article recently published in The Annals of Thoracic Surgery [1].

First, the high number of patients lost to follow-up in the total patient population (501 patients) was clearly stated in the article, together with an adequate explanation. Second, none of the patients analyzed in the subset of patients, where one-patch repair (n = 48) and two-patch repair (n = 23) were compared, were lost to follow-up. Third, it should be emphasized that it was this subgroup analysis which was the focus of the article. The subgroups used for the Kaplan-Meier analysis of freedom from reoperation did not have any patients lost to follow-up. The critical point raised by Dr Corno does not have any impact regarding the interpretation of the results or the conclusions drawn from this study.
