Prenatal diagnosis of a congenital pseudoaneurysm of the mitral-aortic intervalvular fibrosa: a multimodality imaging case report

Year: 2026

Type: article

Abstract: Background: Congenital pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is exceptionally rare, and prenatal diagnosis remains challenging. Case summary: We report a rare case of a congenital P-MAIVF diagnosed prenatally. The fetus was closely monitored throughout pregnancy and after birth. Surgical resection was performed at 12 months because of progressive enlargement and concern for fistula formation. The combination of imaging techniques helped in detecting the complication and guiding management. Postoperative outcome was excellent. Discussion: The diagnosis of such a rare congenital anomaly is challenging, and improving its recognition is essential. Multimodality imaging may help in diagnosis, clinical decision-making, and longitudinal follow-up.
