A szerzők célja volt csecsemőkorban vizsgálni a veleszületett mitralisbillentyű-szűkület és -elégtelenség sebészi kezelését, valamint a komplett atrioventricularis septumdefektus (CAVD) teljes korrekciója során a mitralis billentyű kialakításának, pótlásának lehetőségét. Betegek: 2001 és 2007 között 82, egy évnél fiatalabb csecsemőn a korrekciós műtétet követően 7 betegben (5 hét–7 hónap, 3,5–5 kg) mitralis (bileaflet) műbillentyű korai beültetése vált szükségessé. A két műtét közti idő 0–7 nap, de a legkisebb csecsemőnél intenzív kezelés mellett 38 napot kellett várni az annulus feltágulására, hogy a legkisebb műbillentyű beültethető lehessen. A műbillentyűk típusa: 16 mm-es Carbomedics 2, 16 mm-es ATS 3, 17 mm-es Sorin 1, 19 mm-es Sorin 1. Congenitalis mitralis stenosis, illetve insufficientia miatt 2-2 csecsemőbe kellett 16 mm-es ATS billentyűt beültetni. Eredmény: 30 napos mortalitás 0. Egy-egy csecsemő a 46., illetve a 71. posztoperatív napon szepszisben meghalt. 1–6 (átlag 3) éves utánkövetés: 1 betegben kellett pannust eltávolítani, a betegek panaszmentesek. Az antikoaguláns terápia helyes beállítása nehézséget jelentett. Összefoglalás: Congenitalis mitralis stenosis és elégtelenség, valamint a CAVD sebészi korrekciója már kis súlyú újszülötteken is sikerrel elvégezhető. Kedvezőtlen anatómiai helyzetben a mitralis billentyű kialakításának lehetetlensége esetén csak a műbillentyű-beültetés a megoldás. Ez kilátástalannak tűnő helyzetben (kis mitralis annulus) is elvégezhető jó eredménnyel. (Tudomásunk szerint 3500 g súlyú betegünk a legkisebb, sikeresen operált eset.) Ezt igazolják eseteink korai és középtávú eredményei.

Perivalvular Leakage

Background:This study aimed to evaluate the clinical and surgical characteristics of patients who required reoperation after mechanical mitral valve replacement (MVR).Methods:We retrospectively identified 204 consecutive patients who underwent reoperation after mechanical MVR between 2009 and 2018. Patients were categorized according the reason for reoperation (perivalvular leakage, thrombus formation, or pannus formation). The patients' medical and surgical records were studied carefully and the rates of in-hospital complications were calculated.Results:The mean age was 51±12 years and 44% of the patients were male. The reasons for reoperation were perivalvular leakage (117 patients), thrombus formation (35 patients), and pannus formation (52 patients). The most common positions for perivalvular leakage were at the 6–10 o'clock positions (proportions of ≥25% for each hour position). Most patients had an interval of >10 years between the original MVR and reoperation. The most common reoperation procedure was re-do MVR (157 patients), and 155 of these patients underwent concomitant cardiac procedures. There were 10 in-hospital deaths and 32 patients experienced complications. The 10-year survival rate was 82.2 ± 3.9% in general, and the group of lowest rate was patients with PVL (77.5 ± 5.2%). The independent risk factors were “male” (4.62, 95% CI 1.57–13.58, P = 0.005) and “Hb <9g/dL before redo MV operation” (3.45, 95% CI 1.13–10.49, P = 0.029).Conclusion:Perivalvular leakage was the most common reason for reoperation after mechanical MVR, with a low survival rate in long term follow-up relatively.
