Right ventricle-to-pulmonary artery shunt related complications after Norwood procedure.
OBJECTIVE The right ventricle-to-pulmonary artery (RV-PA) shunt in the Norwood procedure (NP) for children with hypoplastic left-heart syndrome (HLHS) provides stable early hemodynamics and improves survival in many centers. However, lower pulmonary-to-systemic flow ratio causes early cyanosis and may require earlier second-stage procedure. The aim of the study was to present shunt-related resu...
متن کاملRight coronary artery fistula to right ventricle.
1 of 2 DESCRIPTION A murmur was noted in a 2-year-old patient who was otherwise asymptomatic. The patient was born by caesarean section at 37 weeks gestation. No signifi cant family history was present. Clinical examination revealed a continuous murmur at the sternal edge. Echocardiography did not reveal any abnormality. Cardiac catheterisation revealed a communication between the right coronar...
متن کاملComparison of hemodynamics between Norwood procedure and systemic-to-pulmonary artery shunt for single right ventricle patients.
OBJECTIVE Despite that surgical outcomes of patients with hypoplastic left heart syndrome have improved, one of the problems remaining is the high interstage mortality after a stage I Norwood procedure. The purpose of this study was to determine the hemodynamic characteristics of hypoplastic left heart syndrome after a Norwood procedure. We examined the perioperative hemodynamic differences of ...
متن کاملNorwood Procedure for Palliation of Hypoplastic Left Heart Syndrome: Right Ventricle to Pulmonary Artery Conduit vs Modified Blalock-Taussig Shunt.
Patients with hypoplastic left heart syndrome undergo a series of operations to separate the pulmonary and systemic circulations. The first of at least 3 operations occurs in the newborn period, with a stage I palliation. The goal of stage I palliation is to provide pulmonary blood flow and create an unobstructed systemic outflow tract. Advances in surgical techniques and intraoperative and pos...
متن کاملAcute pressure overload of the right ventricle. Comparison of two models of right-left shunt. Pulmonary artery to left atrium and right atrium to left atrium: experimental study
BACKGROUND In right ventricular failure (RVF), an interatrial shunt can relieve symptoms of severe pulmonary hypertension by reducing right ventricular preload and increasing systemic flow. Using a pig model to determine if a pulmonary artery-left atrium shunt (PA-LA) is better than a right atrial-left atrial shunt (RA-LA), we compared the hemodynamic effects and blood gases between the two shu...
