Lutembacher's syndrome: recognition by echocardiography

The typical echocardiographic features of mitral stenosis in association with an enlarged right ventricle and abnormal septal motion are generally consistent with pulmonary hypertension and functional tricuspid regurgitation. In the absence of clinical and echocardiographic features of pulmonary hypertension, the combination of mitral stenosis and "volume overload" of the right ventricle should alert the clinician to the diagnosis of Lutembacher's syndrome. This report discusses a patient with these echocardiographic findings in whom the diagnosis of Lutembacher's syndrome was confirmed by cardiac catheterization.
