The official eligibility criteria

Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.

Inclusion Criteria:

2. RV/LV ratio ≥ 0.9 assessed by diagnostic computed tomographic angiography (CTA) or echocardiogram

Exclusion Criteria:

3. Known serious, uncontrolled sensitivity to radiographic agents

4. Life expectancy \< 180 days

5. Patients on ECMO

6. Pregnant patients

7. Current participation in another investigational drug or device study that may confound the results of this study. Studies requiring extended follow-up for products that were investigational but have since become commercially available are not considered investigational studies

Voxsanity reformats data from public registries into this layout. It does not edit, interpret or add to what the registry published.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
