چکیده
OBJECTIVE To compare the haemodynamics and perioperative course of initial palliation with bilateral pulmonary artery banding (PAB) and the Norwood procedure. METHODS Between April 2004 and December 2007, 43 consecutive children with hypoplastic left heart syndrome (HLHS) or a variant underwent initial palliation (PAB, n=18; Norwood, n=25). Clinical perioperative data were analysed. In the PAB group, lipo-prostaglandin E1 administration was continued with hospitalisation until stage 2 palliation with a bi-directional Glenn shunt and the Norwood procedure. RESULTS There were no significant differences in the age and operative weight of patients who received stage 1 palliation (PAB, 12+/-9 days, 2.7+/-0.6 kg; Norwood, 12+/-8 days, 2.8+/-0.4 kg). The PAB group had more high-risk patients than the Norwood group (PAB, 83%; Norwood, 48%, p=0.04). Increased early and inter-stage mortality were observed in patients who underwent the Norwood procedure (early mortality with PAB, 6% vs Norwood, 12%; inter-stage mortality, 6% vs 27%, respectively). Mortality between stages 1 and 2 was 11% for the PAB group and 36% for the Norwood group. The Kaplan-Meier survival estimate at 1 year did not differ between groups (77% for the PAB group, 64% for the Norwood group). Ductal stenosis was found in one patient in the PAB group during the follow-up period. Twenty-eight patients underwent stage 2 reconstruction, and the patients in the PAB group were younger at the time of surgery (PAB, 116 days; Norwood, 224 days). There were no significant differences between groups in pulmonary artery index regarding body surface area (BSA) (PAB, 179 mm(2)BSA(-1); Norwood, 194 mm(2)BSA(-1)) and the incidence of ventricular dysfunction after stage 2 construction (PAB, 21%; Norwood, 21%). CONCLUSIONS Bilateral PAB with continuous lipo-prostaglandin E1 administration may improve early and intermediate mortality in infants with HLHS. Intimate care with hospitalisation may contribute to the results.

The bilateral pulmonary artery banding for hypoplastic left heart syndrome with a diminutive ascending aorta.
A one-day-old neonate who was diagnosed with hypoplastic left heart syndrome (HLHS), aortic atresia, with a diminutive ascending aorta, and mitral atresia, was referred to us for cardiogenic shock because of excessive pulmonary blood flow. The patient underwent bilateral pulmonary artery banding (bPAB). After bPAB, the patient's hemodynamics were still unstable because of coronary malperfusion,...

OBJECTIVE Hypoplastic left heart syndrome remains a challenge for worldwide surgeons. Initial palliation employing bilateral pulmonary artery banding along with ductal stent implantation and atrial septostomy has been proposed as an alternative approach. However, the surgically placed bands are fixed and may become inadequate after sternum closure or with somatic growth of the patient. We descr...
متن کاملBiventricular Repair after Bilateral Pulmonary Artery Banding as a Rescue Procedure for a Neonate with Hypoplastic Left Heart Complex.
Hypoplastic left heart complex (HLHC) consists of less severe underdevelopment of the left ventricle without intrinsic left valvular stenosis, i.e., a subset of hypoplastic left heart syndrome (HLHS). HLHC patients may be able to undergo biventricular repair, while HLHS requires single ventricle palliation (or transplant). However, there is no consensus regarding the likelihood of favorable out...
