OBJECTIVES The aim of this study was to compare the pulmonary artery (PA) growth after arterial duct (AD) stenting versus modified Blalock-Taussig shunt (MBTS) in neonates with congenital heart disease with duct-dependent pulmonary circulation (CHD-DPC). BACKGROUND Arterial duct stenting is increasingly deemed a reliable alternative to surgical shunt in CHD-DPC. A stented duct might better ad...
Results RV EDV was positively associated with pulmonary regurgitant (PR) volume (b 0.59, p < 1e), tricuspid regurgitant (TR) volume (b 0.24, p < 1e), body surface area (b 0.08, p < 1e), and age (b 0.20, p < 1e). Significant residual outflow tract stenosis (b -0.10, p = 0.01), branch pulmonary artery stenosis (b -0.09, p = 0.02) and RV EF (b -0.38, p < 1e) were negatively associated with RV EDV ...
We report new percutaneous techniques for perforating the pulmonary valve in pulmonary atresia with intact ventricular septum, in 3 newborns who had this birth defect. There was mild to moderate hypoplastic right ventricle, a patent infundibulum, and no coronary-cavitary communications. We succeeded in all cases, and no complications related to the procedure occurred. The new coaxial radiofrequ...
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...
In the present case report, we describe a malformation consisting of a double-outlet right ventricle with an intact ventricular septum diagnosed in a 3-day-old female newborn. To our knowledge 35 cases have been described in the literature. The diagnosis was made by two-dimensional echocardiography and confirmed by angiocardiography. An inadequate opening in the interatrial septum and hypoplasi...
Background -In the Single Ventricle Reconstruction (SVR) trial, one-year transplant-free survival was better for the Norwood procedure with right ventricle-to-pulmonary artery shunt (RVPAS) compared with a modified Blalock-Taussig shunt (MBTS) in patients with hypoplastic left heart and related syndromes. At 6 years, we compared transplant-free survival and other outcomes between the groups. Me...
OBJECTIVES To report a surgical strategy for the Norwood procedure in the hypoplastic left heart syndrome (HLHS) that enables short hypothermic circulatory arrest time and aortic arch reconstruction with autologous pericardium patch. To compare the results of the modified Blalock-Taussig (mBT) shunt and the right ventricle-to-pulmonary artery (RV-PA) conduit procedures as the source of pulmonar...
The initial surgical approach to the infant with pulmonary atresia and intact ventricular (PA-IVS) is to establish an adequate source of pulmonary blood flow and, when possible, relieve right ventricular (RV) outflow obstruction. The selection of patients for pulmonary valvotomy, alone or in combination with a systemic-pulmonary arterial shunt, depends on the presence of an RV outflow tract and...
