Does congenital heart disease severely jeopardise family life and pregnancies? Obstetrical history of women with congenital heart disease in a single tertiary centre.

AIM: Women with congenital heart disease are often considered to be restricted in their obstetrical life and even their marital life. Our single-centre study aimed to determine the real-life situation of these women with regard to successful family life and any pregnancy complications they may experience. METHODS: From our database of adults with congenital heart disease, 160 of 178 women completed a questionnaire and had their files reviewed. They were classified into three groups according to their pregnancy risk - "good condition" group, no pregnancy restriction; "at-risk" group, pregnancy allowed with close follow-up at a tertiary centre; and "contraindicated" group, pregnancy inadvisable. RESULTS: The proportion of women in a relationship was 46% with no difference between the three groups. In the groups where pregnancy was allowed, 55% of women conceived a child. The total incidence of spontaneous abortion was 21%. The rate of caesarean section was 15%. The incidence of cardiac failure was 4.7%, arrhythmia 1.2%, endocarditis 1.2%, hypertension 2.4%, and preeclampsia 1.2%. Foetal complications included prematurity and/or low birth weight (9.5%) and one foetal malformation (0.82%). CONCLUSION: Women with severe congenital heart disease are willing to start a family and are successful in this enterprise. Although the complication rate during pregnancy in congenital heart disease remains high, with good monitoring these pregnancies occur without severe complications and a low rate of medical abortion or caesarean section.

Early results of valved bovine jugular vein conduit versus bicuspid homograft for right ventricular outflow tract reconstruction.

BACKGROUND: Homograft conduits are preferable for right ventricular outflow tract reconstruction in children, but their limited availability remains a major concern. Recently, a valve-containing segment of bovine jugular vein (Contegra, Medtronic Inc, Minneapolis, MN) has been introduced as a potential alternative conduit. METHODS: Early clinical and echocardiographic results of right ventricular outflow tract reconstruction were retrospectively compared between 41 children (mean age, 1.9 years), receiving a Contegra conduit and 36 patients (mean age, 2.7 years) with a size-reduced pulmonary homograft. RESULTS: Clinical outcome was comparable with two early deaths in the homograft group and one in the Contegra group. There were no conduit-related complications in either population. Early echocardiographic assessment showed only trivial to mild regurgitation in 9 homografts versus 17 Contegra conduits. The peak gradient across the right ventricular outflow tract conduit was comparable for both groups, although a larger number of patients, treated with a downsized homograft, had a small gradient at the distal junction with the pulmonary arteries (12 versus 6 patients). None of the patients had a gradient at the valvar level. CONCLUSIONS: The valved bovine jugular vein conduit offers a promising substitute for right ventricular outflow tract reconstruction in infants and children, with an early hemodynamic performance that compares favorably with downsized, bicuspid homografts. Clinical advantages are greater shelf availability and the natural continuity between valve and conduit, which allows proximal infundibular shaping without additional material. However, durability must be determined, even though most of these children will require right ventricular outflow tract reoperation after outgrowing the conduit.

Workload of ambulatory activities in a tertiary paediatric cardiac centre.

BACKGROUND: Few data are available on the evolution in the number of referrals and the spectrum and frequency of issues addressed in paediatric cardiac outpatient clinics. AIM: To assess the volume and range of symptoms and diagnoses in patients, referred to a paediatric cardiac outpatient clinic in an academic hospital setting. METHODS: Data were collected prospectively over 6 months. RESULTS: Historical comparison showed that the number of outpatient visits increased from 819 during the first semester of 2004 to 865, 1045 and 1391 during the first semesters of 2005, 2006 and 2007, respectively. During the 6-month study period in 2007, 854/1391 visits concerned patients with known heart disease; the reason for the visit was follow-up of congenital heart disease (n=616 children, 128 adults), arrhythmia (n=91) or acquired heart disease (n=19). During the visit, the decision to perform diagnostic or therapeutic cardiac catheterization or a surgical procedure was taken in 47 cases. Foetal echocardiography was performed in 60 foetuses and was abnormal in 21 cases. Among the other 477 visits, which concerned patients without known heart disease, the most frequent clinical concern was cardiac murmur (n=193) and there were new diagnoses of congenital heart disease (n=28), ventricular dysfunction (n=2) and arrhythmia (n=7). CONCLUSIONS: The ambulatory paediatric cardiology workload in tertiary academic hospital settings is increasing alarmingly. These data may be helpful in future planning of consultant manpower and in curriculum development for cardiac training of students and residents.
