Platelet inhibition versus direct oral anticoagulation in patients undergoing percutaneous closure of patent foramen ovale or atrial septal defect

You likely can't join if

• - Unable or unwilling to return for required follow-up visits - High likelihood of being unavailable for follow-up or psycho-social condition making study participation impractical - Mechanical heart valves or valvular disease requiring surgery or interventional procedure - Ongoing major bleeding or complicated or recent (<72 hours) major surgery - Severe thrombocytopenia (<50.000/ml) - Mitral valve regurgitation grade 3 or more - Aortic valve stenosis (AVA<1.0cm2 or Pmax>50 mmHg) or regurgitation grade 3 or more - Left ventricular ejection fraction <30% - Life expectancy of less than 1 year - Any indication for long-term oral anticoagulation other than presence/closure of a PFO/ASD (such as atrial fibrillation) - Any indication for long-term (dual) antiplatelet therapy other than presence/closure of a PFO/ASD (such as recent coronary stenting) - Contraindication for the use of rivaroxaban or DAPT (e.g. history of intracranial bleeding) in the investigator's opinion - Pregnant or planning to become pregnant during the time of the study - Estimated glomerular filtration rate <50 ml/min/1.73m2 - Use of medication that significantly interacts with rivaroxaban; medication that inhibits cytochrome P450 3A4 or P-glycoprotein (such as ketoconazole, human immunodeficiency virus (HIV) protease inhibitors, clarithromycin, erythromycin and fluconazole) or induces cytochrome P450 3A4 (such as rifampicin and several anti-epileptic drugs).
