Abstract
ntroduction: The secundum atrial septal defect (ASD)is the 4th most common congenital heart defect
with the incidence ~6-8/1000 births. The device closure of hemodynamically significant ASD is usually
recommended with body weight more than 15kg (usually age>/=3 years) to avoid possible
complications. Interventional closure of secundum ASD in Children’s Clinical University Hospital (CCUH)
in Riga, Latvia was commenced in year 2008. All the pediatric patients with congenital heart diseases
in Latvia undergo treatment in CCUH so the data represent the pediatric population of our country
during the study period.
Aim of the study was to analyze all the patients with age less than 3 years undergoing interventional
closure of secundum ASD in CCUH during years 2008-2018.
Material and methods: This study was an observational retrospective, single center study. We
analyzed demographic data, indications for ASD closure, periprocedural data on complications and
outcomes and the follow-up data.
Results: During the study period of 11 years there were 15 children <3 years old (4 boys, 11 girls), mean
age 1.99years (IQR1.7-2.2), weight 11.8±2.4kg undergoing transvasal ASD closure. 2 patients had
multiple ASDs (13.3%). The transvasal ASD closure was successful in 14 patients (93.3%), but in 1 case
there was embolization of the device into pulmonary artery above bifurcation and the patient had
surgical evacuation of the device and patch closure of ASD (6.7%). There was no mortality or other
serious complications. Immediately after the procedure there were 3 hemodynamically insignificant
residual ASD cases (20%). 14 patients (93%) were followed-up in CCUH for 3.5±2.8 years. At the end of
follow-up (age 5.9±2.9 years) 1 patients had small residual ASD (7%).
Conclusions: Interventional ASD closure in small children (<3 years old and <15kg) can be performed
without major risks in small country with small number of patients
with the incidence ~6-8/1000 births. The device closure of hemodynamically significant ASD is usually
recommended with body weight more than 15kg (usually age>/=3 years) to avoid possible
complications. Interventional closure of secundum ASD in Children’s Clinical University Hospital (CCUH)

without major risks in small country with small number of patients
