BACKGROUND: It is to be expected that avoidance of the atrial suture line during extracardiac Fontan operation (ECFO) decreases the risk of @entity943 . METHODS: Two groups of consecutive @entity1 (23 with lateral tunnel (LTFO) and 24 with extracardiac conduit) who underwent successful Fontan operations between 5/93 and 10/98 were comparatively analyzed. All @entity1 had postoperatively standard ECG and 24-hour monitoring. During follow-up, all @entity1 had 2 - 8 (mean 3) standard ECG recordings per year and 76 % of the @entity1 a 24-hour Holter ECG once a year. RESULTS: Median follow-up after ECFO and LTFO was 2.4 years and 4.5 years, respectively. The incidence of @entity4710 and @entity1168 after ECFO versus LTFO was lower early after operation and during follow-up (p < 0.05). In follow-up, 20 ECFO @entity1 (91 %) versus 11 @entity1 after LTFO (52 %) remained in sinus rhythm (p < 0.01). Pacemaker insertion was required in 7 (33 %) LTFO @entity1 but none of the ECFO @entity1 (p < 0.01). CONCLUSIONS: The extracardiac Fontan operation decreases the incidence of early and medium-term @entity943 . Comparative long-term results are not yet available.

Preliminary analysis of XXXX after the Fontan operation with extracardiac conduit compared with intra-atrial lateral tunnel.
