Abstract:
Mitral regurgitation (MR) is a dynamic condition influenced by positional changes and physical stress. We report a case of severe positional MR in a 74-year-old woman with dilated cardiomyopathy, highlighted by echocardiographic findings of leaflet tethering and restricted mobility. Upright positioning significantly alleviated symptoms and MR severity, underscoring the impact of hemodynamic factors on its clinical presentation.
