[Outcome of 30 congenital atrio-ventricular blocks].
Congenital isolated atrio-ventricular block (CAVB) is a rare pathology, and its management is still rather poorly described through international literature. Within the service of pediatric cardiology leaded by Pr Choussat and Dr Jimenez (Cardiologic Hospital Haut-Lévêque of Bordeaux), we collected from 1980 to 2003, 30 isolated congenital CAVB, constituting the purpose of this retrospective study. Average follow-up is 14 +/- 8.8 years. None death occurred. CAVB are discovered at an average age of 4.8 years old; 6 cases were diagnosed in utero, half of them were associated with maternal lupus. Twenty patients on 30 were fitted with stimulator at an average age of 8.7 +/- 6.9 years old, due to symptoms or bradycardy. Epicardic fitting in VVI mode represents 65% of first approaches, it is followed by endocavitary way for 81% of cases. Cardiac stimulation does not prevent from dilated cardiomyopathy. Among 30 patients 10 were not fitted with stimulator, half of them presents chronotrop insufficiency during effort. As a conclusion, our patients show a good long-term vital prognosis; although CAVB discovered in utero lead to worse prognosis for children.
