Hyperfunction of the subclavian-pulmonary artery anastomosis causing pulmonary vascular disease is uncommon. The mechanism for the late development of an overgenerous shunt is usually obscure. We report the case of a 31-year-old patient with Fallot's tetralogy and Marfan's syndrome who had undergone a right Blalock manoeuvre at the age of 5. At necropsy the Blalock anastomosis was widely patent...

Modified Blalock-Taussig shunts are usually clamped during the successive corrective or palliative surgical procedures carried out to treat underlying congenital heart disease, though at times they may be left permeable for a number of reasons. Subsequently, when this is no longer considered necessary and closure is indicated, the method of choice is percutaneous embolization using various coil...

A four year old boy with pulmonary atresia and ventricular septal defect had an acute cyanotic episode three years after undergoing a right-sided, 6 mm diameter, modified Blalock-Taussig shunt. On admission no continuous murmur could be heard from the shunt and the typical high velocity, continuous flow profile of the shunt could not be identified by Doppler echocardiography. At catheterisation...

We present the case of a patient who underwent a Nikaidoh procedure for total correction of transposition of the great arteries (TGA), ventricular septal defect (VSD), and pulmonary stenosis (PS). A young girl, 2 years and 4 months of age, weighing 3400 g at birth, was diagnosed with TGA, VSD, patent ductus arteriosus (PDA), and left ventricular outflow tract obstruction (LVOTO), with valvular ...
