heart, section, the middle, heart, hypoplastic left heart syndrome, hlhs, hypoplastic left heart describes the underdevelopment, the left side, the heart, left ventricle, aortic valve, aorta, condition is congenital, present at birth, hypoplastic left heart, rare type of congenital heart disease, problem develops, birth, is inadequate growth, the left ventricle, associated structures, aortic, mitral valves that guard the exit, entrance, the ventricle, aorta, blood vessel that carries oxygenated blood, left ventricle, entire body, in patients, left side, the heart is unable to maintain blood circulation, right side, the heart must maintain the circulation, the lungs, extra workload eventually causes, heart to fail, possibility of survival, connection between the right, left side, the heart, blood, pass, a shunt, babies, born, two of these connections, foramen ovale, ductus arteriosus, spontaneously close a few days after birth, structures, allowed to close, baby, hypoplastic left heart syndrome, quickly die, no blood, pumped, no known cause of hypoplastic left heart syndrome, up to 40% of patients, condition have other birth defects, initially, a newborn, hypoplastic left heart, appear normal, first few hours of life, take up to a few days to develop symptoms, lethargy, poor suckling, feeding, shortness of breath, rapid breathing, cold extremities, enlarged liver, poor pulse, pounding heart, bluish, poor skin color, sudden death, in healthy newborns, bluish color occurs in hands, feet, a response to cold, reaction, peripheral cyanosis, a bluish color observed, in the chest, abdomen, lips, tongue is abnormal, central cyanosis, reflects lack of adequate levels of oxygen, in the blood, secondary, heart malformation, circulatory malfunction, central cyanosis often increases, crying, a physical examination, reveals a blue, critically ill patient who, signs of congestive heart failure, liver enlargement, rapid breathing, lethargy, additionally, pulse at various locations, wrist, groin, very weak, an ecg shows enlargement, the right ventricle, the heart, an x-ray, the chest shows heart enlargement, an echocardiogram, the definitive diagnosis shows the tiny left ventricle, a cardiac catheterization necessary, cases to complement the echocardiogram, once the diagnosis of hypoplastic left heart is made, a nunber of things, patient is put on a ventilator to assist, breathing, a medicine, prostaglandin e1 is started, prevent a shunt, the ductus arteriosus from closing, intravenous fluids, started, medicine to help the heart beat stronger, begun, supportive, not solve the problem, next step is surgery, two surgical approaches to hypoplastic left heart syndrome, a heart transplant early in life, that a small donor heart, is very rare, must be available, that the patient, have to take a number of medicines, prevent rejection, the new heart, option, operations done over the first 3 years of life, option, the norwood procedure, stage i, the norwood procedure, the first few days of life, consists of attaching the functioning right ventricle, aorta, vessel that delivers blood, the lungs must still receive blood, a surgically created conduit, tunnel, created to attach the a large artery, in the chest, pulmonary arteries, vessels that lead, lungs, conduit, a blalock-taussig, bt, shunt, stage ii operation, the glenn, hemi-fontan procedure, superior vena cava, vessel that removes deoxygenated blood, head, arms, attached, pulmonary arteries, bt shunt is removed, stage iii, the fontan procedure, inferior vena cava, vessel that returns deoxyganted blood, lower half, attached, pulmonary arteries, performed between the ages of 2-3 years, third stage the patient is no longer blue, cyanotic, norwood procedure is relatively new, outcomes have been good so far, that these patients' hearts eventually, fail, need a heart transplant, easier to transplant an older patient than an infant, left untreated, hypoplastic left heart syndrome is fatal, survival rates, the staged repair continue to rise, surgical technique, postoperative management improve, survival, first stage is more than 75%, important to note that the size, function, the right ventricle, important determinants of outcome after surgery, untreated, heart failure continues to worsen, result in death, infant shows any, the symptoms of hypoplastic left heart syndrome, contact health care provider, no known prevention, hypoplastic left heart syndrome, many congenital diseases, hypoplastic left heart syndrome, uncertain, linked to any maternal diseases, behavior.
