REPRODUCTION &SURVIVAL POST CARDIAC MALFORMATION REPAIR

    Description

    In the last 25 years, surgical advances have led to correction of
    congenital heart defects (CHD) in children who otherwise would not have
    lived to adulthood. This study has two major objectives: 1) to determine
    mortality, morbidity (reoperation, arrhythmia, endocarditis), and
    disability after repair of CHD, and the major risk factors which predict
    these events; and 2) to assess the safety of pregnancy to women with
    corrected CHD, and the risk of prematurity and recurrence of CHD in
    offspring. This study would create a registry comprised from all Oregon children
    undergoing surgical repair of CHD and would study the eight most prevalent
    defects: ventricular septal defect(VSD), atrial septal defect(ASD),
    pulmonic stenosis(PS), tetralogy of Fallot(TOF), coarctation of the aorta,
    aortic stenosis(AS), transposition of the great arteries(TGA), and patent
    ductus arteriosus(PDA). This proposal is an extension of an identical
    project complied by the investigators for TOF(N=310), VSD(N=217), and
    ASD(N=287). 83% of all subjects were successfully followed after a median
    of 9 years of observation; more than 20 years of follow-up was achieved in
    more than 75 subjects. All cases of surgical correction of PS, AS, TGA, PDA and coarctation
    performed in children age 18 or younger in Oregon from 1958 to 1981 will be
    added into the registry. Preoperative, operative and postoperative
    variables for each patient will be entered into the data base at chart
    review. Follow-up for each patient will be by mailed questionnaire,
    telephone survey, or use of the National Death Index. Questionnaires will
    assess major morbidity, functional status and reproductive status;
    reproduction and important events will be confirmed from physician's
    records. Follow-up every two years will continue for all members of the
    registry including patients with TOF, VSD and ASD to determine intercurrent
    events, reproduction or change in functional status. Actuarial analysis and the Cox proportional hazards model will determine
    survival, major events and their risk factors. This study will add knowledge of late survival and morbidity to a data base
    which lacks this information. Additionally, we will gather some of the
    first data regarding pregnancy and outcome after repair of CHD; this is
    vitally important as more adults than ever before with CHD are of
    child-bearing age.
