Fig. 2From: Natural progression of cardiac features and long-term effects of enzyme replacement therapy in Taiwanese patients with mucopolysaccharidosis IIThe relationships between age and severity of cardiac valve abnormalities in the 48 patients with MPS II (severity score: 3: severe, 2: moderate, 1: mild, 0: normal). a MS, mitral stenosis (r = 0.629, p < 0.01); b MR, mitral regurgitation (r = 0.386, p < 0.01); c AS, aortic stenosis (r = 0.510, p < 0.01); d AR, aortic regurgitation (r = 0.477, p < 0.01). The blue circles represent the age and severity of cardiac valve abnormalities in the 48 patients. The open and closed circles represent mild and severe forms of patients with MPS II, respectivelyBack to article page
