Cyanotic (right to left shunt) Congenital Heart Disease (CHD) lesions can be easily remembered with the 1,2,3,4,5 method.
紫紺型先天性心臟病（CHD）（右至左分流) 病變可以用以下12345 法，很容易的記住。

1- Truncus Arteriosis (ONE trunk)
１－動脈干 （一個主干）
2- Transposition of the Great Vessels (TWO vessels flipped)
２－大動脈（血管）轉位（兩條血管轉位）
3- TRIcuspid Atresia
３－三尖瓣閉鎖
4-TETRAlogy of Fallot
４－法洛四聯癥
5- Total Anomolous Pulmonary Venous Return (TAPVR=5 words/letters)
５－全部肺靜脈回流異常 (全部肺靜脈回流異常（TAPVR），總共5個字母)。
A few other important DUCTAL-DEPENDENT lesions: Coarctation of the Aorta, Hypoplastic Left Heart Syndrome, and Pulmonary Atresia.
其他幾個重要的導管依賴型病變： 主動脈縮窄、 左心發育不全綜合征、 肺動脈閉鎖。
Patients present to the emergency department within the first week of life in severe distress, including hypoxia, tachypnea, and hypotension.
患者出生后一周因嚴重癥狀到急診就診：包括缺氧、呼吸急促和低血壓。
The above cyanotic CHD all reflect DUCTAL-DEPENDENT lesions, meaning they need a widely open PDA (which closes in the first week of life) to maintain sufficient oxygenation for viability.
所有上述的紫紺型先心病反映導管依賴病變，意味著他們需要高度開放的 PDA （它在出生后的第一周就會關閉） 保持足夠的氧合。
These patients will not survive without timely intervention with prostaglandin (PGE1), so be sure to initiate this life-saving medication as soon as possible! Side effects include apnea…be prepared to intubate your neonate!
這些病人如果沒有及時的應用前列腺素 （PGE1）是無法存活的，所以一定要盡快使用這種拯救生命的藥物（前列腺素）！這個藥物的副作用包括呼吸暫停...準備給你的新生兒插管 ！
