Calcified Postoperative Epicardial Granuloma

Abstract

A sterile calcified granuloma on the external surface of a right ventriculotomy in an 8-year-old boy was identified four years after closure of a ventricular septal defect. He had no symptoms, but a systolic ejection murmur was identified and disappeared after resection of the lesion. Sensitivity to silk suture material is suggested by the operative findings and a history of multiple silk suture sinuses developing in his uninfected original thoracotomy incision.
