title: Extremely high-pressure dilation with a new noncompliant balloon.
abstract: Calcified nondilatable lesions remain a challenge for the interventional cardiologist, and they are becoming more frequent in the catheterization laboratory as the overall complexity of interventions increases. Stent underexpansion is the main risk factor for restenosis and thrombosis, which is the most feared complication for the interventionalist.In this report, we present our initial experience (8 patients) with a new noncompliant high-pressure balloon, the OPN NC balloon, a double-layered device. When we used this device at 40 atm, our rate of success was reasonable (75%) and our patients experienced no adverse sequelae. The OPN NC balloon appears to offer a new means of dilating lesions or underexpanded stents when other noncompliant balloons have failed. Safety seems reasonable, even at pressures as high as 40 atm.
