The complication rate of intravascular ultrasound (IVUS) in a multicenter pediatric heart transplant population: A study of the international pediatric IVUS consortium.

Most AE during routine PHT coronary evaluation with IVUS were minor and not directly related to the use of IVUS. The number of coronary related AE was similar to a registry-based report of coronary angiography alone. Efforts to minimize IVUS-related complications should be focused on preventing coronary artery vasospasm.
