BACKGROUND: This study sought to determine long-term outcomes of a primary Damus-Kaye-Stansel (DKS) procedure in patients with a functional single ventricle and to compare the results with those of our historical control subjects who underwent pulmonary artery banding before the DKS procedure.
METHODS: The study reviewed the medical records of all patients who underwent the DKS procedure at the German Heart Center of Munich, Germany between December 1994 and December 2019.
RESULTS: The DKS procedure was performed as initial palliation in 52 patients (primary DKS group) and as staged palliation after pulmonary artery banding in 24 patients (staged DKS group). The median follow-up period after the DKS procedure was 8.9 years in the primary DKS group and 8.0 years in the staged DKS group. The survival rates at 10 years after the DKS procedure were 89% in the primary DKS group and 68% in the staged DKS group (log-rank P = 0.04). Before total cavopulmonary connection, the pressure gradient through the systemic ventricular outflow tract was significantly lower in the primary DKS group than in the staged DKS group (P < .001). At last follow-up echocardiography, reduced ventricular function was observed in 1 patient in the primary DKS group and in 7 patients in the staged DKS group (P < .001). The degree of neoaortic regurgitation was significantly higher in the staged DKS group than in the primary DKS group (P < .001).
CONCLUSIONS: A primary DKS procedure in patients with a functional single ventricle and potential systemic ventricular outflow tract obstruction is recommended to obtain favorable long-term survival with preserved ventricular function and competent semilunar valve function.
