Computational Analysis of Hybrid Norwood Circulation With Distal Aortic Arch Obstruction and Reverse Blalock-Taussig Shunt

Computational analysis of hybrid Norwood circulation with distal aortic arch obstruction and reverse Blalock-Taussig shunt.

BACKGROUND The hemodynamics characteristics of the hybrid Norwood (HN) procedure differ from those of the conventional Norwood and are not fully understood. We present a multiscale model of HN circulation to understand local hemodynamics and effects of aortic arch stenosis and a reverse Blalock-Taussig shunt (RBTS) on coronary and carotid perfusion. METHODS Four 3-dimensional models of four H...

The Blalock and Taussig Shunt Revisited

The systemic to pulmonary artery shunts are done as palliative procedures for cyanotic congenital heart diseases ranging from simple tetralogy of Fallots (TOFs)/pulmonary atresia (PA) to complex univentricular hearts. They allow growth of pulmonary arteries and maintain regulated blood flow to the lungs till a proper age and body weight suitable for definitive corrective repair is reached. We h...

False aneurysm following modified Blalock-Taussig shunt.

A nine month old infant with life threatening tracheal compression due to a Blalock-Taussig shunt aneurysm is described. Successful surgical management is discussed.

Pseudoaneurysm following modified Blalock Taussig shunt.

The modified Blalock-Taussig (BT) shunt is a common palliative procedure for congenital cyanotic heart disease (CHD) with diminished pulmonary blood flow(1). In developing countries, definitive surgery usually gets delayed due to limited resources and expertise(2). Children with cyanotic CHD and BT shunt often present to the pediatrician resulting in some of the complications of BT shunt being ...
