Double orifice mitral valve (DOMV) can be found in approximately 1% of all patients with congenital heart disease and commonly occurs in association with other cardiovascular malformations.1 If not resulting in relevant regurgitation or stenosis, the malformation can go unnoticed and may be found incidentally. However, severe valvar dysfunction can bear a significant challenge for surgical repair, and a clear understanding of the underlying pathology and valvar structure is necessary to achieve good results.
