Why the study?
Long-term complications such as right heart failure, tricuspid regurgitation, and arrhythmias remain problematic after physiological repair of congenitally corrected transposition of the great arteries due to the systemic right ventricle.
Does double valve replacement and CRT-P upgrade improve cardiac function in a patient with congenitally corrected transposition of the great arteries and systemic right ventricular failure?
Does double valve replacement and CRT-P upgrade improve cardiac function in a patient with congenitally corrected transposition of the great arteries and systemic right ventricular failure?
Double valve replacement combined with CRT-P upgrade successfully improved systemic right ventricular function and heart failure symptoms in an adult patient with ccTGA late after physiological repair.
May inform individualized reoperation and CRT strategies in adult ccTGA; leaves open durability and generalizability.
修正大血管転位症の機能的修復術後は右心室が体心室となるため,遠隔期に右心不全,三尖弁閉鎖不全,不整脈などが問題となる.今回,機能的修復術後に,3回目の再開胸手術を施行した1例を経験したので報告する.症例は26歳の女性で,修正大血管転位症に対して3歳時にセントラルシャント手術を経て,10歳時に機能的修復術を施行された.20歳時に左室肺動脈導管再置換術を施行されたが,その後は心不全,不整脈のために入院治療を繰り返していた.今回,大動脈弁および三尖弁閉鎖不全症に対して,大動脈弁および三尖弁置換術を施行した.高度房室ブロックに対して永久ペースメーカー植え込み術後であったが,今回,左心室に心外膜リードを挿入し心室再同期療法を導入した.人工心肺離脱時には大動脈バルーンパンピングを要し,術後も長期のカテコラミン投与を要したが,術後60日目に自宅退院した.術後2年9か月現在,心不全の増悪なく経過している.
