Modified Blalock-Taussig shunt is:
End to side anastomosis of subclavian artery to a pulmonary artery
Side to side anastomosis of main pulmonary artery to aorta
Side to side anastomosis of subclavian artery to a pulmonary artery using a conduit
Anastomosis of superior vena cava to right pulmonary artery
Correct answer: 3. Side to side anastomosis of subclavian artery to a pulmonary artery using a conduit
In classic Blalock-Taussig shunt, the subclavian artery is divided and anastomosed to the pulmonary artery as an end to side anastomosis. In modified Blalock – Taussig shunt, a Gore – Tex graft is used to connect the subclavian artery to the pulmonary artery. In Davidson shunt, a Gore-Tex graft is used to connect ascending aorta to main pulmonary artery [Tomasian A, Malik S, Shamsa K, Krishnam MS. Congenital heart diseases: post-operative appearance on multi-detector CT-a pictorial essay. Eur Radiol. 2009 Dec;19(12):2941-9]. Glenn shunt connects the superior vena cava to right pulmonary artery.

Complication of Fontan procedure:
Plastic bronchitis
Protein losing enteropathy
Heart failure
All of the above
None of the above
Correct answer: 4. All of the above
Heart failure was the mode of death in 34% in a series of 600 adult Fontan survivors. Arrhythmia or sudden death was the reason in 24% [Ohuchi H, Inai K, Nakamura M, Park IS, Watanabe M, Hir...
