title: Coronary angioplasty requiring extraordinarily high balloon inflation pressure.
abstract: Two cases are presented in which extraordinarily high balloon inflation pressures (20 and 17 atm) were required to successfully dilate a saphenous vein graft stenosis and a right coronary artery stenosis. The clinical application of high balloon inflation pressures and balloon selection is discussed.
