Study summary

The goal of this observational study is to determine the efficacy of rivaroxaban treatment for intracardiac thrombi resolution in pediatric patients (\< 16 years old) diagnosed with intracardiac thrombosis. The main question it aims to answer is: Does rivaroxaban treatment resolve the thrombosis during a 3-month treatment?

Participants already taking rivaroxaban as part of their regular medical care for thrombosis resolution. They will undergo monthly visits to check that the treatment is progressing correctly and that no major bleeding has occurred. After 3 months of treatment, they will repeat the radiological imaging investigation to verify the actual resolution of the thrombosis.

Read the detailed description

The Investigators will enroll all the consecutive pediatric patients (\< 16 years old) treated with rivaroxaban (dosage based on patient's body weight - 0.9 mg/Kg/Day) due to intracardiac thrombosis (ICT) suspected by echocardiography and confirmed with cardiac computed tomography (CCT) or magnetic resonance (CMR) imaging. All the participants will be treated with enoxaparin for 7 days before the rivaroxaban implementation. The treatment will last for 3 months.

The participants will undergo monthly visits to check that the treatment is progressing correctly and that no major bleeding has occurred. Bleeding severity will be assessed utilizing the Bleeding Assessment Scale in Critically Ill Children (BASIC). CCT/CMR will be repeated to confirm the thrombosis resolution. After 3 months of treatment, they will repeat the radiological imaging investigation to verify the effective resolution of the thrombosis, or it will be continued for another 3 months if there is no resolution of the thrombosis.

Study population

Pediatric patients (neonates and pediatrics) diagnosed with intracardiac thrombosis at any possible cardiac site (right/left ventricle, right/left atria, or auricola).

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Intracardiac thrombosis demonstration at echocardiography and CMR/CCT confirmation
  • Given from the parents or tutors

Exclusion criteria

Exclusion Criteria:

  • \< 38 weeks of gestational birth
  • \< 10 days of oral feeding and body weight
  • \< 2.6 Kg
  • Any major or bleeding event or abnormal coagulation test results within 10 days prior to the enrollment for the whole population
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
