Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: NONE
- Phase: PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Is a child with cardiac disease who is at risk for thromboembolic complications and requires at least 3 months antithrombotic anticoagulant prophylaxis~Either one of the following:~1. a child with cardiac disease who has a history of cardiac shunt occlusion/thrombosis, with shunt still in place (secondary prevention).~   OR~2. a child with cardiac disease who requires (including those already taking, and those not yet taking) anticoagulation for primary prevention of TE.~Cardiac conditions known to significantly increase the risk of thrombosis (hence, indications for primary TE prevention) are defined in Antithrombotic Therapy and Prevention of Thrombosis. Some examples of cardiac conditions at risk of thrombosis are Fontan surgery, heart failure, Kawasaki disease, and Blalock-Taussig and Glenn surgery.~* Is a male or female child between 1 and \<18 years of age (children between 38 weeks gestational age and 1 year of age will be included in the study, however, only after the safety and efficacy data of 50 subjects between 1 and \<18 years of age in the edoxaban arm have been evaluated at the end of the 3-month treatment period)~* Has parent(s)/legal guardian(s) or legally acceptable representative who is informed and provides signed consent for the child, to participate in the study with edoxaban treatment. Pediatric participants with appropriate intellectual maturity will be required to sign an assent form in addition to the signed informed consent from the parent(s)/legal guardian(s) or any legally acceptable representative.~* If a female subject of childbearing potential, tests negative for pregnancy at Screening and consents to avoid becoming pregnant by using a locally approved contraception method throughout the study~Exclusion Criteria:~* Has evidence of symptomatic venous or arterial thrombosis and/or asymptomatic intracardiac thrombosis confirmed by a transthoracic echocardiogram during study screening period~* Has mechanical heart valve(s)~* Has active bleeding or high risk of bleeding contraindicating treatment with anticoagulant~* Takes antithrombotic therapy (other than low-dose aspirin) that is not protocol-related~* Administration of rifampin is prohibited during the study and subjects on concomitant use of rifampin are excluded~* Has any hepatic disease associated with coagulopathy leading to a clinically relevant bleeding risk~* Has estimated glomerular filtration rate (eGFR) \<30% of normal for age and size~* Has stage 2 hypertension defined as blood pressure systolic and/or diastolic confirmed \>99th percentile plus 5 mmHg~* Has thrombocytopenia or life expectancy less than three months~* Has had Fontan procedure with a history of or signs/symptoms suggestive of protein-losing enteropathy~* Is pregnant or breastfeeding~* Has a contraindication to the use of heparin and/or vitamin K antagonist (VKA)~* Has any condition that, as judged by the Investigator, would place the participant at increased risk of harm if he/she participated in the study, including contraindicated medications identified in the protocol
