- Tetralogy of Fallot (TOF) (OMIM #187500) is the most frequent conotruncal congenital heart defect (CHD) with a range of intra- and extracardiac phenotypes. TBX5 is a transcription factor with well-defined roles in heart and forelimb development, and mutations in TBX5 are associated with Holt-Oram sy

- OBJECTIVES: Robotic technology has been applied to atrial septal defect (ASD) repair for more than 10 years, but the number of cases reported is limited and results of long-term follow-up are not clear. This study reports on a large group of patients who underwent totally robotic ASD repair on an ar

欠損孔の部位による分類
- 二次孔欠損は卵円窩の位置に欠損孔がある ≠ 卵円孔開存
- 静脈洞型は上、下大静脈入口部付近や冠静脈洞の欠損であり、しばしば部分肺静脈還流異常を伴う。
- 3. 一次孔欠損(15%)、(部分型心内膜床欠損としてあつかわれるとか)
- 一次孔欠損(心内膜床欠損不完全型)は、房室弁孔に隣接する房室中隔の欠損であり、房室弁(僧帽弁、三尖弁)の裂隙(クレフト)や閉鎖不全を伴う。
病態
- 心房で左-右短絡 → 右心系に容量負荷 → 右心不全
- 右心系の容量負荷 → 肺血流↑ →肺血管床の閉塞性病変・肺高血圧症
検査
聴診
- 下部左胸骨縁に拍動聴取。拡張した右室の収縮:RV heave
- II音:widened, fix slitting pattern 固定性分裂
- 上左胸骨縁:収縮期雑音 :肺動脈弁に多くの血流が流れることによる → 相対的PS
- 下左胸骨縁:拡張期中期雑音:三尖弁を通って血流がたくさん流れ込むため。 → 相対的TS
- 心房間の圧格差は大きくないので、ASDの欠損孔を血液が通ることによる雑音はない。
