Reoperative valve surgery after open-heart valve surgery: a report of 155 cases / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To summarize the characteristics of reoperative valve surgery after previous open-heart valve surgery.@*METHODS@#From 1996 to 2010, 155 patients who underwent reoperative valve surgery, either valve replacement or tricuspid annuloplasty or the repair of perivalvular leakage were included in the study. The reoperative interval was 1-266 (94.82 ± 85.37) months. All surgeries were carried out with extracorporeal circulation under moderated hypothermia. The cardioplegic solution in cold crystal or blood was used if heart beating was stopped during the surgery.@*RESULTS@#The total in-hospital mortality was 5.81%, while it was 2.75% from 2005 to 2010. The end-diastolic dimension, size of atrium and ventricles were reduced after the reoperation. Ventricular arrhythmia and low cardiac output were the most frequent complications.@*CONCLUSION@#The success rate of reoperative valve surgery can be improved by the distinctive therapeutic strategies based on the clinical characteristics and therapy principles obtained from practice experiences.
