Systolic anterior motion in hypertrophic cardiomyopathy: a fluid–structure interaction computational model [PDF]

Theoretical and Computational Fluid Dynamics, 2021
We present direct numerical simulations for the pathophysiology of hypertrophic cardiomyopathy of the left ventricle of the human heart. This cardiovascular disorder manifests itself through systolic anterior motion (SAM), a drift of the mitral leaflets towards the aortic subvalvular region, sometimes causing ventricular obstruction during systole ...

Systolic anterior motion of mitral chordae tendineae: prevalence and clinical implications in liver transplantation [PDF]

Anesthesia and Pain Medicine, 2020
Background Although systolic anterior motion (SAM) of the mitral valve anterior leaflet is well-known to cause hemodynamic perturbation in many anesthetic situations, the prevalence and clinical implication of SAM of mitral chordae tendineae (chordal SAM)

Systolic anterior motion of the anterior mitral valve leaflet begins in subclinical hypertrophic cardiomyopathy. [PDF]

Eur Heart J Cardiovasc Imaging, 2023
Abstract Aims Anterior mitral valve leaflet (AMVL) elongation is detectable in overt and subclinical hypertrophic cardiomyopathy (HCM). We sought to investigate the dynamic motion of the aorto-mitral apparatus to understand the behaviour of the AMVL and the mechanisms of left ventricular outflow tract

Cardiac Resynchronization Therapy for Mitral Systolic Anterior Motion in a Child

The Annals of Thoracic Surgery, 2007
We describe the successful use of cardiac resynchronization therapy for treatment of mitral valve systolic anterior motion with left ventricle outflow tract obstruction after re-excision of a subaortic membrane and septal myectomy in a 12-year-old child. In the recovery phase, a total atrioventricular block persisted.

Hypertrophic cardiomyopathy: the edge-to-edge secures the correction of the systolic anterior motion [PDF]

European Journal of Cardio-Thoracic Surgery, 2016
Although septal myectomy is the technique of choice for hypertrophic cardiomyopathy, the surgical management of concomitant mitral valve lesions is controversial. Various complex surgeries have been proposed to address mitral valve lesions. We propose a simple option using an edge-to-edge mitral valve repair through the aortic valve in addition to the ...

Significant left ventricular outflow tract obstruction secondary to systolic anterior motion in a patient without hypertrophic cardiomyopathy: An echocardiographic study

Journal of the Saudi Heart Association, 2018
Dynamic left ventricular outflow tract obstruction (LVOTO) can be hemodynamically significant and can adversely affect the heart and quality of life. It is caused by systolic anterior motion (SAM) of the anterior mitral valve into the LVOT. The mechanism

Transient systolic anterior motion with junctional rhythm after mitral valve repair in the intensive care unit

Critical Ultrasound Journal, 2018
Systolic anterior motion (SAM) after mitral valve repair (MVR) can adversely affect hemodynamics due to exacerbation of left ventricular outflow tract obstruction and mitral regurgitation.

Systolic Anterior Motion of the Mitral Valve Post-Heart Transplant Secondary to an Unusual Mechanism. [PDF]

Cureus
In this case report, we discuss the critical interdependence of structure and function in demonstrating systolic anterior motion (SAM) of the mitral valve after repeat heart transplantation, where residual apical tissue of the explanted heart remained in
