Abstract
BACKGROUND: The aim of this study was to investigate the efficiency of tricuspid valve detachment (TVD) during the surgical treatment of perimembranous ventricular septal defects (VSDs) and to compare the early and mid-term results to patients without TVD in terms of tricuspid insufficiency. METHODS: A total of 170 patients who had undergone surgical closure of perimembranous VSDs between November 2012 and January 2019 were included in this study, of whom 50 had an additional TVD procedure during the surgery. All patients were examined by transthoracic echocardiography before and after the operation with regular intervals, and the tricuspid valve function was then evaluated. RESULTS: There was no significant difference between subgroups with an unchanging degree of TVR, however, the result was also similar among those who had a decreased degree of TVR at any level (p = 0.271, p = 0.451). At the end of the study, all patients were in New York Heart Association class I. CONCLUSIONS: We suggest that, in appropriate patients, VSD closure can be safely performed with an additional TVD application through an incision of the septal leaflet of the tricuspid valve without impairing the valve function or reducing the growth potential of the valve at midterm follow-up.
