CASE: 40s man complaint of dyspnea after mitral valve repair for MVP. Echo study showed a dynamic LVOT obstruction(SAM). DISCUSSION: SAM of MV with ventricular septal contact is responsible for dynamic obstruction of LVOT,most of time can be seen in hypertrophic cardiomyopathy. It has also been noted in hyperkinetic circulatory states,in aortic regurgitation, during in fusion of dopamine in a patient in shock,and following mitral valve repair for myxomatous mitral valve prolapse.
