Qhov Tseem Ceeb Qhov txawv - Cyanotic vs Acyanotic Congenital Heart Defects
Kev yug me nyuam zoo tag nrho yog ib qho txuj ci tseem ceeb uas tau ploj lawm qhov txaus ntshai vim nws tshwm sim ntau zaus. Ntau yam tuaj yeem mus tsis ncaj ncees lawm thaum lub sijhawm tsim thiab kev loj hlob ntawm fetus. Cov kab mob plawv uas peb yuav tham hauv tsab xov xwm no kuj yog cov teeb meem uas tshwm sim vim yog qhov tsis zoo ntawm qee yam ntawm lub plawv thaum lub sij hawm embryological theem. Raws li lawv cov npe qhia, cyanosis tsuas yog pom nyob rau hauv cyanotic congenital plawv tsis xws luag thiab tsis nyob rau hauv lawv cov acyanotic counterparts. Tab sis qhov sib txawv tseem ceeb ntawm cyanotic thiab acyanotic congenital lub plawv tsis xws luag yog tias kev txav ntawm cov ntshav yog los ntawm sab xis mus rau sab laug ntawm lub cyanotic tsis xws luag thaum lub zog ntawm cov ntshav yog los ntawm sab laug mus rau sab xis ntawm lub plawv hauv lub plawv. kab mob acyanotic.
Cyanotic Congenital Heart Defects yog dab tsi?
Cyanotic congenital lub plawv tsis xws luag yog vim qhov tsis xws ntawm cov hlab ntsha hauv lub cev thaum yug los uas muab cov xim xiav rau ntawm daim tawv nqaij uas hu ua cyanosis. Cyanosis yog tshwm sim los ntawm shunting ntawm cov ntshav los ntawm sab xis mus rau sab laug ntawm lub plawv, txo cov oxygen saturation thiab nce cov ntsiab lus ntawm deoxygenated hemoglobin hauv cov ntshav.
Cov kab mob hauv qab no suav nrog hauv pawg no
- Fallot's tetralogy
- Kev hloov pauv ntawm cov hlab ntsha loj
- Tricuspid atresia
Fallot's Tetralogy
Plaub qhov tseem ceeb ntawm Fallot's tetralogy yog,
- ventricular septal defect
- Subpulmonary stenosis
- Overriding aorta
- Right ventricular hypertrophy
Cov teeb meem no yog vim qhov kev hloov pauv ntawm anterosuperior ntawm infundibular septum thaum lub sij hawm embryological theem.
Morphological nta
Lub plawv feem ntau yog loj thiab muaj cov yam ntxwv khau raj.
Tshuaj Kho Mob
Cov neeg mob TOF tuaj yeem muaj sia nyob mus rau hauv cov neeg laus txawm tias tsis muaj kev kho kom raug. Subpulmonary stenosis yog qhov kev txiav txim siab ntawm qhov hnyav ntawm cov tsos mob. Nyob rau hauv cov ntaub ntawv ntawm ib tug me me subpulmonary stenosis, daim duab kho mob yuav zoo ib yam li cov VSD cais. Tsuas yog qhov hnyav ntawm stenosis tuaj yeem ua rau tus kab mob cyanotic. Qhov hnyav ntawm subpulmonary stenosis thiab hypoplasticity ntawm pulmonary hlab ntsha yog ncaj qha proportional.
Daim duab 01: Fallot's Tetralogy
Kev hloov pauv ntawm cov hlab ntsha loj
Qhov malformation ntawm lub truncal thiab aortopulmonary septa yog lub hauv paus embryological ntawm tus mob no. Ventriculoarterial tsis sib haum xeeb yog qhov tseem ceeb ntawm cov kab mob pathological.
Kev ntsuas tus kab mob nyob ntawm peb yam tseem ceeb
- Kev sib xyaw ntshav
- Degree of hypoxia
- Muaj peev xwm ntawm txoj cai ventricle los tswj lub cev kev ncig
Nrog rau kev loj hlob ntawm tus me nyuam, kev ua haujlwm tsis tu ncua ntawm txoj cai ventricle uas ua raws li lub cev ventricle ua rau nws qhov hypertrophy. Tib lub sijhawm, sab laug ventricle raug atrophy vim qhov txo qis ntawm cov hlab ntsws kev ncig.
Tricuspid Atresia
Qhov ua tiav ntawm lub qhov ncauj ntawm tricuspid valve hu ua tricuspid atresia. Kev sib cais asymmetrical ntawm AV kwj dej yog qhov cuam tshuam hauv embryological. Widened mitral valve thiab txoj cai ventricular hypoplasia yog qhov tseem ceeb morphological nta. Qhov kev kwv yees feem ntau tsis zoo, thiab tus neeg mob tuag hauv thawj tsib xyoos ntawm lub neej.
Dab tsi yog Acyanotic Congenital Heart Defects?
Acyanotic congenital lub plawv tsis xws luag kuj yog vim lub hauv paus txheej txheem tsis xws luag nyob rau hauv lub circulatory system. Tab sis cyanosis tsis pom nyob rau hauv cov kab mob no vim tias qhov txaus siab ntawm deoxygenated hemoglobin tsis tsim vim muaj ntau yam laj thawj.
Cov xwm txheej hauv qab no suav tias yog acyanotic congenital plawv tsis xws luag
- Obstructive lesions- pulmonary stenosis, aortic stenosis, Coarctation ntawm aorta
- Atrial septal defect (ASD)
- Ventricular septal defect (VSD)
- Patent ductus arteriosus
- YPulmonary stenosis
- Atrioventricular septal defect
Atrial Septal Defect (ASD)
Cov no yog vim qhov tsis zoo ntawm lub septum uas cais ob lub atria. Peb yam tseem ceeb ntawm ASD tau piav qhia.
- Ostium primum
- Ostium Secundum
- Sinus venosus defect
Tshuaj Kho Mob
Feem ntau ntawm cov neeg mob ASD feem ntau nyob twj ywm asymptomatic. Cov cim qhia hauv qab no tuaj yeem raug tshem tawm thaum kuaj mob plawv.
- Systolic ejection yws
- Chest X-ray qhia tau hais tias cardiomegaly nrog cov hlab ntsws tseem ceeb thiab lub teeb PA tseem ceeb.
- Kev kho plawv catheterization tuaj yeem pom qhov nce ntawm oxygen saturation ntawm SVC thiab sab xis atrium thaum sib tov.
Qhov tsis xws luag yuav tsum tau kho los ntawm kev phais ua ntej 4-5 xyoos.
Ventricular Septal Defect (VSD)
Cov no yog ntau yam kab mob hauv lub plawv thiab tau muab faib ua peb pawg raws li thaj tsam ntawm ventricular septum uas muaj qhov tsis zoo.
- Membranous defect – defect yog nyob rau hauv lub membranous septum
- Cov nqaij mos - cov leeg nqaij thiab apical feem ntawm lub septum raug cuam tshuam
- Infundibular defect -defect nyob hauv qab lub ntsws li qub
Nyob rau hauv feem ntau ntawm cov mob, qhov tsis xws luag regresses spontaneously. Kev cuam tshuam tsuas yog yuav tsum tau yog tus neeg mob pom cov tsos mob thiab cov tsos mob ntawm lub plawv tsis ua haujlwm.
Daim duab kho mob zoo ib yam li ASD. Lub auscultation ntawm holo systolic yws yws hauv qab ntawm sab laug sternocostal ntug qhia tau tias muaj VSD. Chest X rays tuaj yeem pom cardiomegaly thiab lub plawv vasculature tseem ceeb. Cov tsos mob ntawm lub plawv tsis ua hauj lwm tshwm sim tsuas yog nyob rau hauv cov neeg mob uas muaj ib tug loj defect nyob rau hauv lub septum.
Daim duab 02: VSD
Patent Ductus Arteriosus
Lub fetal ductus arteriosus muaj nyob rau hauv lub plab hauv plab txhawm rau txhawm rau pab txhawb kev sib txawv ntawm cov ntshav los ntawm cov hlab ntsha pulmonary mus rau qhov qis aorta, thiab cov kab mob no feem ntau kaw tsis pub dhau ob peb lub lis piam tom qab yug me nyuam. Nws qhov kev mob siab rau thaum tseem me nyuam mos yog hu ua patent ductus arteriosus.
Coarctation ntawm Aorta
Qhov nqaim ntawm lub aorta ntawm qhov chaw los ntawm qhov chaw ductus arteriosus emanates yog hu ua coarctation ntawm lub aorta. Nws feem ntau tshwm sim ua ke nrog lwm yam mob plawv xws li bicuspid aortic valve. Cov neeg mob dhau los ua cov tsos mob thaum thawj peb lub hlis ntawm lub neej.
Kev nthuav qhia kho mob suav nrog,
- YSystemic hypoperfusion
- YMetabolic acidosis
- Congestive cardiac failure

Summary – Cyanotic vs Acyanotic Congenital Heart Defects
Cyanotic thiab acyanotic congenital lub plawv tsis xws luag yog vim lub hauv paus structural defects ntawm lub plawv. Hauv daim ntawv cyanotic ntawm qhov tsis xws luag, kev txav ntawm cov ntshav yog los ntawm sab xis mus rau sab laug ntawm lub plawv. Cov ntshav txav los ntawm sab laug mus rau sab xis hauv pawg acyanotic ntawm qhov tsis xws luag. Qhov no yog qhov sib txawv tseem ceeb ntawm cyanotic thiab acyanotic plawv tsis xws luag.
