BACKGROUND AND OBJECTIVES: [corrected] In this study, decision and timing of fenestration closure are discussed. We review our experiences with transcatheter occlusion of fenestration or residual baffle leak using Amplatzer occluder.
PATIENTS AND METHODS: We have retrospectively reviewed the cath lab records of 26 patients who have undergone closure of fenestration (or another baffle leak) in period of 2002 to July 2006. Patients with the previous fenestrated Fontan procedure (intracardiac lateral tunnel, extracardiac conduit) with the presence of clinically important cyanosis, arterial desaturation less than 88 %, previously described leak by echocardiography, impaired exercise capability, absence of effusions and appropriate hemodynamic parameters were included in the study.
RESULTS: The most frequent group were patients with hypoplastic left heart syndrome (HLHS) (27 %), second most common was L-transposition of great vessels (TGA), tricuspidal valve atresia (TA) and atresia of pulmonary artery (PA) (all of them 15.4 %).
CONCLUSIONS: Our results confirm that after adjusting the hemodynamical risk, transcatheter fenestration occlusion in high risk patients might be a safe and effective method to significantly increase arterial O2 saturation. The long term benefits of closure especially at exertion are yet to be shown (Tab. 2, Ref 21). Full Text (Free, PDF) www.bmj.sk.
