Left Ventricular Outflow Tract Obstruction and Systolic Anterior Motion of Mitral Valve After Myxomatous Mitral Valve Repair

Left ventricular outflow tract obstruction and systolic anterior motion of the mitral valve after myxomatous mitral valve repair is due to excess tissue of mitral valve among numerous other factors. A patient who had myxomatous mitral valve and acute mitral regurgitation due to chordae rupture was admitted for mitral valve repair. The hospital course of the patient was not significantly different compared to other patients. On the 40th postoperative day, the patient experienced syncope and came to ER. The patient showed severe left ventricular outflow tract obstruction and systolic anterior motion of mitral valve. The patient was treated medically and was discharged with normal echo findings. We report this case with brief review of related literatures.
