1 Flashcards
Acyanotic Heart Defects include
ASD
VSD
AVSD or AVCD
PDA
Describe the pressure in ASD
Pressure in the lungs may build up. Over time, there
will be less oxygen in the blood that goes to the body
ASD where the mixing occurs
RT Atrium
What is the most common congenital heart lesion
VSD
What happens to pulmonary circulation and LT side of the heart VSD
increased pulmonary
blood flow, increased pulmonary venous return
to the left side of the heart, and subsequent left
ventricular volume overload.
Why the total volume decrease VSD
Bc some flow to the aorta then to the body and the rest will back flow to RT ventricular,pulmonary artery,lung, pulmonary vain and normal circulation
Why the have high HR
The body need the o2 as quick as possible
Heart contracts faster to compensate the lost volume
Reed AVSD
✅
What happens in PDA
Ductus arteriosus: a blood vessel that connects the
pulmonary artery and the aorta.
Opening in DA blood flow from aorta to pulmonary artery to lungs mixed blood
Most common preterm cardio disease
PDA
What other complications of pda
pulmonary
edema resulting from pulmonary
overcirculation.
PDA treatment
Positive pressure PEEP
cyanotic congenital heart lesions are
Ø TOF
Ø Transposition of the great arteries
Ø Truncus arteriosus
Ø Tricuspid atresia
Ø Total anomalous venous return
Explain TOF
VSD acyanotic LT to RT shunt
Overriding aorta the aorta is shift to the RT and takes blood from both ventricles mixed blood goes to the body
Pulmonary Stenosis narrow Pulmonary valve blood accumulate in the RtV and cannot pass the valve easily to get oxygen
Right ventricular hypertrophy so RT side will contract harder to eject the blood from RT ventricular to Pulmonary artery
Tet spells
Hypoximea
Syncope desbenya
TRUNCUS ARTERIOSUS
Aorta and pulmonary artery merge together deoxygenated blood supply the body though the aorta
Pulmonary artery takes mixed blood to lungs
Usually diagnosed prenatally via ultrasound.
TRUNCUS ARTERIOSUS
TRANSPOSITION OF THE GREAT ARTERIES
aorta arises from the
right ventricle and the pulmonary artery arises from
the left ventricle.
RtV to aorta to body and back to RtV side
LtA to LtV to pulmonary artery to lung then back to Lt atrium
TOTAL ANOMALOUS VENOUS RETURN
Pulmonary veins carrying oxygenated blood
are not connected to the left atrium but to Rt atrium
RA to RV to PA to lungs to PV to RA
No blood reaches LT heart
Atrial septal defect or patent foramen ovale
must present otherwise this condition is
fatal which condition
TAVR
AORTIC STENOSIS why does it happen
bicuspid aortic valve (congenital defect), meaning
that the aortic valve consists of two functional
leaflets instead of three.
Symptoms of AS
tachypnea, exercise intolerance,
fatigue, chest pain, poor feeding and others
PULMONIC STENOSIS
Obstruction in the right ventricular
outflow tract from pulmonic stenosis
causes increased workload on the right
ventricle and can cause right ventricular
hypertrophy
Hypoplastic left heart syndrome (HLHS) is a of the descending thoracic aorta
rare congenital heart defect in which the left side of the heart is severely underdeveloped
.
