Computational Fluid Dynamics Analysis of Blalock-Taussig Shunt

A Computational Fluid Dynamics Study on Bidirectional Glenn Shunt Flow with an Additional Pulsatile Flow Through a modified 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...

Transcatheter occlusion of a Blalock-Taussig shunt with a detachable balloon in a child.

A case of transcatheter occlusion of a Blalock-Taussig shunt with a detachable silicone filled balloon is described. This 11 year old boy had previously had a repair of tetralogy of Fallot together with ligation of a large Blalock-Taussig shunt. Though there was a good surgical result, the shunt proved to be incompletely closed leaving a significant left to right shunt. As an alternative to a f...

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 ...

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.
