Comparative StudyClinical features of the systolic anterior motion of the mitral valve among patients without hypertrophic cardiomyopathy.
The prevalence and clinical features of the systolic anterior motion of the mitral valve (SAM) without hypertrophic cardiomyopathy (HCM) have not been studied well. ⋯ Non-HCM SAM prevalence was 0.3% in the Japanese population. Non-HCM SAM correlated with older age, sigmoid septum, and a lower LVOT-PG compared with HCM SAM. Among non-HCM SAM, valvular SAM showed a significant symptom, higher LVOT-PG, and more pronounced mitral regurgitation than chordal SAM.
