Long Term Safety of Clopidogrel in Neonates/Infants With Systemic to Pulmonary Artery Shunt Palliation (CLARINET LT)
Long Term Safety Study in Patients Included in the CLARINET Study With Cyanotic Congenital Heart Disease Palliated With a Systemic-to-pulmonary Artery Shunt and for Whom the Shunt is Still in Place at One Year of Age
This study is the extension of the CLARINET study [NCT00396877 -EFC5314] in neonates or infants with cyanotic congenital heart disease palliated with a systemic-to-pulmonary artery shunt.
The primary objective was to assess the safety up to 18 months of age of the extended use of Clopidogrel 0.2 mg/kg/day in patients for whom the shunt was still in place at one year of age.
The secondary objective was to assess the efficacy on the occurrence of shunt thrombosis requiring intervention or any death.

Number of Participants With Bleeding Events
Tidsramme: Up to a maximum of 6 months
|
All bleeding events experienced during the study period were collected as for any Adverse Event. The 'on-treatment' period was defined as the period from inclusion in the extension study up to 28 days after treatment discontinuation, and participants who experienced bleeding events during that period were counted. |
Up to a maximum of 6 months

|
Number of Participants According to Bleeding Type/Etiology
Tidsramme: Up to a maximum of 6 months
|
For all reported bleeding events, the type and the etiology of the bleeding event were collected.
Participants who experienced bleeding events during the 'on-treatment period' were counted by bleeding type and etiology.
