Résumé
The aim of this study was to evaluate the outcomes of right ventricular outflow tract stenting for palliation during the newborn and infancy periods. Between January 2013 and January 2018, a total of 38 patients (20 males, 18 females; median age 51 days; range, 3 days to 9 months) who underwent transcatheter right ventricular outflow tract stenting in three centers were retrospectively analyzed. Demographic characteristics, cardiac pathologies, angiographic procedural, and clinical follow-up data of the patients were recorded. The diagnoses of the cases were tetralogy of Fallot (n=27), double outlet right ventricle (n=8), complex congenital heart disease (n=2), and Ebstein"s anomaly (n=1). The median weight at the time of stent implantation was 3.5 (range, 2 to 10) kg. Five cases had genetic abnormalities. The median pre-procedural oxygen saturation was 63% (range, 44 to 80%), and the median procedural time was 60 (range, 25 to 120) min. Acute procedural success ratio was 87%. Reintervention was needed in seven of patients due to stent narrowing during follow-up. During follow-up period, seven cases died. Total correction surgery was performed in 26 patients without any mortality. While a transannular patch was used in 22 patients, valve protective surgery was implemented in two patients, and the bidirectional Glenn procedure was performed in two patients. Based on our study results, right ventricular outflow tract stenting is a form of palliation which should be considered particularly in cases in whom total correction surgery is unable to be performed due to morbidity.

BACKGROUND

METHODS
METHODS
Between January 2013 and January 2018, a total of 38 patients (20 males, 18 females; median age 51 days; range, 3 days to 9 months) who underwent transcatheter right ventricular outflow tract stenting in three centers were retrospectively analyzed. Demographic characteristics, cardiac pathologies, angiographic procedural, and clinical follow-up data of the patients were recorded.
RESULTS
RESULTS
The diagnoses of the cases were tetralogy of Fallot (n=27), double outlet right ventricle (n=8), complex congenital heart disease (n=2), and Ebstein"s anomaly (n=1). The median weight at the time of stent implantation was 3.5 (range, 2 to 10) kg. Five cases had genetic abnormalities. The median pre-procedural oxygen saturation was 63% (range, 44 to 80%), and the median procedural time was 60 (range, 25 to 120) min. Acute procedural success ratio was 87%. Reintervention was needed in seven of patients due to stent narrowing during follow-up. During follow-up period, seven cases died. Total correction surgery was performed in 26 patients without any mortality. While a transannular patch was used in 22 patients, valve protective surgery was implemented in two patients, and the bidirectional Glenn procedure was performed in two patients.
CONCLUSION
CONCLUSIONS
Based on our study results, right ventricular outflow tract stenting is a form of palliation which should be considered particularly in cases in whom total correction surgery is unable to be performed due to morbidity.
