Why
  1. The study's title name Down Syndrome, a narrower term within Congenital, Hereditary, and Neonatal Diseases and Abnormalities.
Confidence
High: the new condition is named in the study's own title. Of 46 hand-checked studies reclassified this way, 72% were exactly right and 89% in the right disease family; the registry's first term was right for 4% (measured 2026-10-21). How we classify →

Study summary

Failure to thrive and difficulty gaining weight is a sign of uncompensated congestive heart failure (CHF). Infants with Trisomy 21 and complete atrioventricular canal defects (CAVC) frequently develop uncompensated CHF and weight gain failure pre-operatively. A weight of 5 kg has been suggested as optimal for timing of CAVC repair. A delay in surgical repair often occurs if weight gain stalls and reaches a plateau prior to reaching 5 kg. A retrospective review performed by Kogon, et al, of children undergoing surgery for VSD at CHOA at Egleston recently reported that age and weight at surgery may not, however, be associated with adverse surgical outcome.

The purpose of this study is to determine the optimal timing for surgical correction of CAVC in Trisomy 21 infants based on reaching a plateau of failed weight gain despite maximal anti-congestive and nutritional therapy.

Read the detailed description

A retrospective chart review of 100 infants with Trisomy 21 and CAVC operated at CHOA at Egleston between January 1, 2001 and March 24, 2006 will be performed. Graphs of birth weight and rate of weight gain over time will be plotted for each patient and for the group as a whole. The point of reaching a plateau of weight gain will be decided for each patient and indexed for birth weight. Medical management will be detailed, i.e. all medications and all dietary information (caloric density of formula, route of administration). This medical management will be indexed as a function on the weight gain chart. Medical complications (such as respiratory infections, gastroenteritis, hospitalizations, and additional non-cardiac medications) will likewise be plotted and segmented according to position relative to the weight gain plateau. Age at eventual surgery and whether surgical date was delayed by complications will be noted. Surgical cardiopulmonary bypass time and morbidity and mortality will be noted. Postoperative length of ventilator support, length of stay in the CICU and total length of stay will be determined and also displayed as a function of body weight and as a function of time at plateau weight. Postoperative morbidity and mortality for the three months after repair will be noted, including all cause hospital re-admissions and outpatient medical complications (such as respiratory infections, gastroenteritis, and the need for continued medications for CHF).

The record gives a start of Jan 2001, a primary completion of Mar 2006 and a completion of Feb 2008. It does not say whether these dates are actual or estimated.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 16, 2012, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
