Randomized trial shows similar stent expansion between super high-pressure and scoring balloons in calcified coronary lesions, indicating both approaches prepare complex vascular plaque.
In patients with severely calcified coronary artery lesions, preparation with a super high-pressure balloon versus a scoring balloon was associated with comparable stent expansion on intravascular imaging and a trend towards improved angiographic performance. Visual summary. A ComparIson of Strategies to PrepAre SeveRely CALCified Coronary Lesions: the ISAR-CALC randomised trial.
