Does simulated anterior mitral leaflet splitting reduce left ventricular outflow tract obstruction in a computational model of systolic anterior motion?
A novel 3D-0D computational model successfully simulates the hemodynamic benefits of anterior mitral leaflet splitting in reducing LVOT obstruction caused by systolic anterior motion.
Yousef Alharbi (2024) studied Systolic anterior motion and left ventricular outflow tract obstruction. Anterior mitral leaflet splitting (computational simulation) vs. Before splitting (computational simulation) was evaluated on Flow pattern, pressure gradient, and occlusion at the left ventricular outflow tract. A 3D-0D computational model successfully replicated left ventricular outflow tract occlusion and demonstrated that simulated anterior mitral leaflet splitting reduces the obstruction.
