Modified norwood procedure A retrospective chart review compared modified Norwood procedure outcomes between children with HLHS (n = 40) The Norwood procedure is a palliative procedure that is the first of three stages in the surgical treatment of hypoplastic left heart syndrome. Ann Thorac Surg Between January 2008 and February 2010, 16 patients underwent Norwood-type operation after previous bilateral PAB. METHODS HLHS-specific anatomical This study aimed to compare the outcomes of the modified Norwood procedure for these two groups at a single center. The mean age and weight at operation were 17 days (2 days-2 months) However, most conduits are unvalved, and the use of valved xenografts was abandoned during the early era of this operation. Background: Classic first-stage Norwood repair of hypoplastic left heart syndrome uses a homograft patch enlargement to obtain an unobstructed aorta and The Norwood procedure is a complex surgical intervention performed in neonates born with hypoplastic left heart syndrome or other forms of single ventricle heart disease. All but 1 patient underwent a modified Norwood procedure with an RV-PA conduit. in the classic Norwood procedure, Ishino K, Stumper O, DeGiovanni JJ, et al:The modified Norwood procedure for hypoplastic left heart syndrome: early to intermediate results of 120 patients with particular reference to aortic Background: To determine and compare outcome of the modified Norwood procedure using either a systemic to pulmonary artery (SPA) shunt or right ventricle to pulmonary artery (RV-PA) Right ventricle-to-pulmonary artery shunt versus modified Blalock-Taussig shunt in the Norwood procedure for hypoplastic left heart syndrome—influence on early and late haemodynamic status. A high-flow, low-pressure We report a modified Norwood stage I procedure for tricuspid atresia, transposition of great arteries, and hypoplastic right aortic arch with complete vascular ring. Fraser,Jr, MD, and Roger B. The Norwood procedure can be performed with several variations including a sustained total all-region (STAR) perfusion technique, introduced at our institution 5 years ago and well described in a prior Operative Techniques We describe a surgical technique that two patients underwent a modified Norwood procedure without circulatory arrest and myocardial ischemia. As a solution, a U-shaped division of the branch PAs from the posterior wall of MPA was suggested. With two follow-up surgeries, they can survive infancy and even become teens and young adults. One was 13-day-old female Two approaches can be taken in the Stage I modified Norwood procedure: (1) For an extremely hyperplastic ascending aorta, its diameter is only 2–3 mm, that is, much smaller The modified Norwood procedure (continued):A, Once all of the ductal tissue was resected, the lesser cur-vature of the arch was opened from the left subclavian artery to the ascending Stage 1 of the modified Norwood procedure comprises an aortic arch reconstruction via a side-to-side anastomosis of the main pulmonary artery (PA) to the ascending aorta (Ao), an atrial septectomy, and a modified Modified Norwood procedure for hypoplastic left heart syndrome.

PubMed. At the University of Michigan, 303 patients having the Norwood In this study, we introduced a modified Norwood procedure [pulmonary artery trunk-saving method (PATS)] and evaluated the results. A high-flow, low-pressure Norwood procedure consists of a staged surgical approach that creates a new systemic circuit to transition an infant to definitive repair. An interstage home monitoring program (HMP) was Background— The Norwood procedure for stage 1 palliation of hypoplastic left heart syndrome is performed with either the modified Blalock-Taussig (MBTS) or the right ventricle–to–pulmonary artery (RVPA) shunt. In this A retrospective chart review compared modified Norwood procedure outcomes between children with HLHS (n = 40) and children with other single-ventricle malformations (n The Norwood procedure is a three-stage heart surgery to create a new functional systemic circuit in patients with hypoplastic left heart syndrome. 5 to 8 mm (median 3 mm).
