What this trial studies

This observational study aims to compare the morbidity and health outcomes of patients with pulmonary atresia with intact ventricular septum (PA-IVS) who have either univentricular or biventricular circulation. Participants aged 15 years and older will be assessed for mortality, quality of life, comorbidity, cardiac function, and work capacity through questionnaires and various medical examinations, including echocardiograms and MRIs. The study seeks to determine if significant differences exist between the two groups regarding these health metrics.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 15 years or older who were born with pulmonary atresia with intact ventricular septum.

Not a fit: Patients younger than 15 years old at the start of the study will not benefit from this research.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the health outcomes of different circulatory patterns in patients with PA-IVS, potentially guiding treatment decisions.

How similar studies have performed: While this study addresses a specific comparison within a rare condition, similar observational studies have shown success in elucidating health outcomes in congenital heart defects.
