Pulmonary artery banding before Norwood procedure
The Annals of Thoracic Surgery, 2003Described here is the use of bilateral pulmonary artery banding as a means to achieve effective restoration of adequate systemic blood flow before a Norwood procedure in two newborns with hypoplastic left heart syndrome who presented after birth with a severe imbalance of Qp/Qs and multiorgan system dysfunction despite usual pharmacologic and ...

Comprehensive Aristotle Score: Implications for the Norwood Procedure
The Annals of Thoracic Surgery, 2006Aristotle score is emerging as a reliable tool to measure surgical performance. We estimated the comprehensive Aristotle score for the Norwood procedure, correlated it with survival, and considered its impact on surgical management of hypoplastic left heart syndrome.Comprehensive Aristotle score was retrospectively calculated for 39 consecutive Norwood

Norwood procedure to hypoplastic left heart syndrome
The Japanese Journal of Thoracic and Cardiovascular Surgery, 1998Since March 1992, 25 neonates and small infants with HLHS have undergone a modified Norwood procedure. The mean age and weight at operation were 17 days (2 days-2 months) and 2.7 kg (1.6-3.3 kg). Isolated cerebral and/or myocardial perfusion (ICMP) with direct anastomosis of aorta and pulmonary artery was utilized since January 1995 to 16 patients ...

Norwood Procedures and Sano Modification
2013Hypoplastic left heart syndrome (HLHS) is characterized by hypoplasia of the left heart and varying degrees of hypoplasia or atresia of the aortic valve and ascending aorta. It is included in the spectrum of conditions that can result in a cardiac circulation with a functionally single ventricle. Left untreated, HLHS is invariably lethal.

For infants with HLHS, pulmonary vascular resistance is high, often due to the presence of severe pulmonary hypertension; therefore, Fontan surgery should not be performed immediately, but in stages. At present, three stages of the staged surgery are advisable: Stage I Norwood surgery (neonatal), Stage II Norwood surgery (6 months after Stage I surgery)

[Postoparative Management of the Norwood Procedure].
Kyobu geka. The Japanese journal of thoracic surgery, 2023The Norwood procedure still has a high mortality rate of about 15%, and the surgery and its postoperative management require the meticulous care. Of particular importance is maintaining an appropriate balance between systemic and pulmonary blood flow in the face of ever-changing circulatory conditions, for which various parameters must be understood ...

The norwood procedure – does the type of shunt determine outcome?
The Thoracic and Cardiovascular Surgeon, 2007Stage I palliation of hypoplastic left heart syndrome (HLHS) and its variants is usually performed by a Norwood operation. The management of pulmonary blood flow during this procedure remains controversial. The RV-to-PA conduit (RVPAC) has been proposed as the better alternative compared to a systemic-to-pulmonary shunt (SPS).A retrospective single ...

Survival After Norwood Procedure in High-Risk Patients
The Annals of Thoracic Surgery, 2020Multiple single-ventricle populations are noted to be at increased risk for mortality after the Norwood procedure. Preoperative risk factors include low birth weight, restrictive/intact atrial septum, obstructed pulmonary veins, ventricular dysfunction, and atrioventricular valve regurgitation.

Modified Norwood procedure for hypoplastic left heart syndrome
The Annals of Thoracic Surgery, 1995Since June 1994, we have used a modification of the Norwood technique in 13 patients presenting with the hypoplastic left heart syndrome or similar variants.This technique involves coarctation repair, arch reconstruction, and creation of a neo-ascending aorta using autologous great vessel tissue only. Pulmonary blood flow is provided by a central shunt

The Norwood Procedure: In favor of the RV-PA Conduit
Seminars in Thoracic and Cardiovascular Surgery: Pediatric Cardiac Surgery Annual, 2013Evolution of the Norwood procedure has culminated in there currently being three treatment strategies available for initial management: the 'classical' Norwood (utilizing a Blalock-Taussig shunt), the Norwood with right-ventricle to pulmonary artery (RV-PA) conduit, and the 'hybrid' Norwood procedure utilizing bilateral pulmonary artery banding and ...
