Indications for surgical intervention in Kawasaki's disease include which of the following?

D. Progressive stenosis in the left anterior descending coronary artery.

DISCUSSION: The indications for surgical treatment of Kawasaki's disease include: (1) progressively stenotic coronary lesions demonstrated on coronary arteriography, with no distal coronary aneurysms with stenosis; (2) localized aneurysm with significant stenosis in the left main coronary artery; (3) significant stenosis in two coronary arteries; (4) presence of collateral vessels arising from a coronary artery with a proximal aneurysm; (5) progressive stenosis in the left anterior descending coronary artery; and (6) presence of a left ventricular aneurysm. Advanced thrombosis of coronary aneurysms causing critical stenoses in multiple coronary arteries is the most common indication for surgical intervention.
