Risk factors for a positive neoaortic arch gradient after stage I palliation for hypoplastic left heart syndrome.
BACKGROUND Providing unobstructed systemic blood flow is one goal of stage I palliation for hypoplastic left heart syndrome. Although clinically significant obstruction is defined when the arch gradient exceeds 15 mm Hg, any positive gradient constitutes obstruction, which may impair ventricular function. We sought to identify risk factors before stage I palliation that result in a positive neo...
متن کاملHypoplastic left heart syndrome
Hypoplastic left heart syndrome (HLHS) refers to the abnormal development of the left-sided cardiac structures, resulting in obstruction to blood flow from the left ventricular outflow tract. In addition, the syndrome includes underdevelopment of the left ventricle, aorta, and aortic arch, as well as mitral atresia or stenosis. HLHS has been reported to occur in approximately 0.016 to 0.036% of...
متن کاملHypoplastic left-heart syndrome.
Hypoplastic left heart syndrome may be accurately diagnosed during fetal life. Prenatal diagnosis provides the opportunity for parents to make an informed choice about their options, including surgery, nonintervention postnatally or termination of pregnancy. Short to medium term survival continues to improve for a condition that was previously invariably lethal. There continues to be a signific...
متن کاملAortic arch obstruction after the Norwood procedure for hypoplastic left-heart syndrome is it inevitable? Is it preventable?
William I. Norwood, working at the Boston Children’s Hospital, developed and refined a surgical procedure that permitted babies born with hypoplastic left-heart syndrome (HLHS) to survive and enjoy life (1). The high mortality rates reported during the 1980s have gradually declined as various surgeons and medical centers have refined both the surgical techniques and the preand post-operative ca...
متن کاملCoarctation of the aorta, interrupted aortic arch, and hypoplastic left heart syndrome in three generations.
Five members in three generations of a family were affected by a congenital heart disease. Four of them had mild or severe coarctation of the aorta (CoA), either isolated or in association with other cardiac defects. Fetal echocardiography allowed prenatal diagnosis in one pregnancy at risk. This family suggests that a rare form of CoA could be the result of an autosomal dominant mutation with ...
