We report a case of a giant cardiac lymphaticovenous malformation arising from the atrioventricular groove in a 38-year old Caucasian female. Cardiac vascular lesions are rare and tend to be poorly described in the literature. Lymphaticovenous malformations are present at birth and develop due to errors in venolymphatic development. As the tumour enlarged, the patient experienced significant shortness of breath on exertion. At resection, the mass measured 6.0 cm anterior-posterior ×10.4 cm craniocaudal. The mass was found to be adhered tightly to the coronary sinus. Histologically, the lesion was composed of dilated vascular and lymphatic channels within a fatty stroma. The mass was resected without complications.
