Modern management of systolic anterior motion of the mitral valve.
Systolic anterior motion (SAM) of the mitral valve (MV) can be a life-threatening condition. The SAM can result in severe left ventricular outflow tract obstruction and/or mitral regurgitation and is associated with an up to 20% risk of sudden death (which is substantially lower in hypertrophic cardiomyopathy (HCM)). The mechanisms of SAM are complex and depend on the functional status of the v...
متن کاملSystolic anterior motion of the mitral valve.
APPEARANCE Appearance: Systolic anterior motion of the mitral valve (SAM) is a paradoxical motion of the anterior, and occasionally posterior, mitral valve leaflet towards the left ventricular outflow tract (LVOT) during systole (Fig. 1 and see Videos, Supplemental Digital Content 1 and 2, which demonstrate characteristic SAM with subaortic stenosis and mitral regurgitation on cine steady state...
متن کاملSystolic anterior motion of the mitral valve and outflow obstruction after mitral valve reconstruction.
Multiple papillomas ofthe tracheobronchial tree are rare in children and adults. We describe a 42-year-old woman with multiple papillomatous-like tumors involving the trachea and bronchi. The limited tissue samples obtained during fiberoptic bronchoscopy initially lead to a benign histopathologic diagnosis; concurrent cytology studies strongly suggested oat cell carcinoma. The biopsy specimen o...
متن کاملTransient mitral regurgitation due to mitral valve prolapse accompanied by systolic anterior motion of the mitral valve.
A grade 4/6 systolic murmur, systolic anterior motion of the mitral valve (SAM), and severe mitral regurgitation (MR) documented by two-dimensional Doppler echocardiography developed suddenly on the structurally normal heart of a patient with idiopathic portal hypertension. The patient did not have signs of congestive heart failure and the aforementioned phenomenon disappeared completely when t...
متن کاملSystolic anterior motion of the mitral valve in the absence of asymmetric septal hypertrophy.
Asymmetric septal hypertrophy (ASH) is considered the unifying link in the spectrum of hypertrophic cardiomyopathies. ASH and mitral valve systolic anterior motion (SAM) are the two most important echocardiographic criteria for the diagnosis of idiopathic hypertrophic subaortic stenosis (IHSS). Ten patients found have SAM without ASH were studied. Septal thickness, thickening, and excursion wer...
