hypoplastic left heart syndrome

18 Jul

this is a condition where the left side of the heart is not properly developed. its congenital, meaning its a birth defect.

as shown in the diagram, ths left ventricle is extremely small. and the aorta is miserably small too. atrial septal defect means that the oxygenated blood from the left atrium mixes with the deoxygenated blood from the right atrium.

so basically what this means is that there is a small volume of blood leaving the heart to be transported around the body, and even this small amount of blood is not effectively oxygenated, but a mixture of oxygenated and deoxygenated blood.

what actually happens in a heart with this condition is that the right ventricle pumps blood to both the lungs and the body. i’m really not sure how that happens. seems that blood flows out of the right ventricle through patent ductus arteriosus.. which closes within days of the child being born.

since a person cant sustain very long with such a condition, ppl mostly die early.

blogging abt this cos the papers reported a singaporean boy who survived 15 yrs with this condition, and just died last sunday..

read the story of a boy who has this condition.

    Hypoplastic Right Heart Syndrome (HRHS):Causes,Symptoms and Treatment

    Hypoplastic Right Heart Syndrome (HRHS) is a condition that is even more rare than Hypoplastic Left Heart Syndrome (HLHS). HRHS refers to the underdevelopment of the right side structures of the heart, which means that the chambers, valves and related blood vessels on the right side of the heart are malformed.

    The most critical defect in HLHS is the small, underdeveloped left ventricle. This chamber is normally very strong and muscular so it can pump blood to the body. When the chamber is small and poorly developed, it will not function effectively and cannot provide enough blood flow to meet the body’s needs. For this reason, an infant with hypoplastic left heart syndrome will not live long without surgical intervention.
