Key result
Percutaneous transluminal coronary angioplasty was unsuccessful in dilating a severe coronary stenosis in a 13-year-old boy with Kawasaki disease, reducing stenosis minimally from 95.3% to 90.4%.

Is percutaneous transluminal coronary angioplasty effective for treating coronary stenosis in patients with Kawasaki disease?
PTCA may be ineffective and potentially risky for treating coronary stenosis caused by Kawasaki disease, questioning its value in this patient population.
PTCA may be ineffective for Kawasaki stenosis; leaves open optimal revascularization strategies in children.
A 13-year-old boy with severe coronary stenosis due to Kawasaki disease underwent percutaneous transluminal coronary angioplasty (PTCA). The guide wire and the balloon catheter easily passed through the stenosis in the left anterior descending artery. However, effective dilatation could not be achieved even when the balloon size was increased to 2.5 mm in diameter. We discontinued further inflation of the balloon because serious resistance was encountered on withdrawal of the balloon catheter. In patients with Kawasaki disease, the value of PTCA as a treatment for coronary stenosis is questionable.

Nishimura et al. (1992) conducted a case report in Kawasaki disease with severe coronary stenosis (n=1). Percutaneous transluminal coronary angioplasty (PTCA) was evaluated on Successful dilatation of coronary stenosis. Percutaneous transluminal coronary angioplasty was unsuccessful in dilating a severe coronary stenosis in a 13-year-old boy with Kawasaki disease, reducing stenosis minimally from 95.3% to 90.4%.
