Monitoring organ perfusion in infants undergoing PDA closure

A Comparative Study of Medical Management vs Transcatheter PDA Occlusion Using Near-Infrared Spectroscopy

Not applicable Interventional University of Louisville · NCT06359522

This study is testing how well two different methods of closing a heart condition in infants affect blood flow and oxygen levels in their brains and kidneys.

What this trial studies

This study is a prospective observational analysis of infants in the Norton Children's Hospital NICU who are undergoing either transcatheter PDA occlusion or medical closure of PDA. It aims to compare changes in organ perfusion, specifically cerebral and renal oxygen saturation, using Near-Infrared Spectroscopy (NIRS) monitoring. Patients will have NIRS probes placed prior to treatment to establish baseline readings, which will be monitored during and after the procedure for up to five days. The study will analyze the differences in regional oxygen saturation between the two treatment methods.

Who should consider this trial

Good fit: Ideal candidates include infants in the NICU with hemodynamically significant PDA requiring closure through either medical therapy or transcatheter occlusion.

Not a fit: Infants with other significant congenital heart diseases that could impact systemic blood flow may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the most effective method for managing PDA in infants, potentially improving outcomes related to organ perfusion.

How similar studies have performed: Previous studies have indicated that NIRS monitoring can effectively assess organ perfusion, suggesting that this approach may yield valuable data.
