Frequency of 22q11 deletions in patients with conotruncal defects.
OBJECTIVES This study was designed to determine the frequency of 22q11 deletions in a large, prospectively ascertained sample of patients with conotruncal defects and to evaluate the deletion frequency when additional cardiac findings are also considered. BACKGROUND Chromosome 22q11 deletions are present in the majority of patients with DiGeorge, velocardiofacial and conotruncal anomaly face ...
متن کاملGuidelines for 22q11 deletion screening of patients with conotruncal defects.
Goldmuntz et al. (1) have reported the frequency of 22q11 deletions in a prospectively ascertained sample of 251 patients with conotruncal defects. Deletions were found in 17.9% of the patients, including 50% with interrupted aortic arch (IAA), 34.3% with truncus arteriosus (TA), and 15.9% with tetralogy of Fallot (TOF). Although this study was designed to determine the frequency of deletions i...
متن کامل"Intramural" residual interventricular defects after repair of conotruncal malformations.
BACKGROUND We report an unusual type of residual interventricular communication in patients with conotruncal malformations in which the aorta is completely or partly aligned with the right ventricle (RV). Interventricular communications after surgical repair usually result from additional defects, patch dehiscence, or incomplete closure and lie in the septal plane. However, after a right ventri...

متن کاملRisk factors for conotruncal cardiac defects in Atlanta.
Because the causes of conotruncal cardiac defects are poorly understood, a case-control study was conducted to investigate maternal risk factors for conotruncal cardiac defects. Eligible cases included all infants who were born from 1976 through 1980 to residents of the five county metropolitan Atlanta area and diagnosed with truncus arteriosus, transposition of the great arteries or tetralogy ...
