Abstract
The case of a Loeys-Dietz Syndrome patient undergoing mitral valve repair and composite aortic root and valve replacement is here described: pre-operative CT scan unraveled a previously misdiagnosed Morgagni hernia (anterior diaphragmatic), containing omentum only, compressing the right ventricle. Intra-operatively, an abnormal oxygenated blood backflow into the left ventricle was observed, post-operatively found to be caused by major aorto-pulmonary collateral arteries. This is the first case of Morgagni hernia and systemic-pulmonary shunt ever reported associated with Loeys-Dietz Syndrome. These congenital features may be important in both phenotyping and surgical management.
Keywords: Loeys-Dietz Syndrome; Morgagni hernia; aortic root aneurysm; aorto-pulmonary collateral arteries; mitral regurgitation.
