Abstract
Left ventricular outflow obstruction (LVOTO) is a potential complication following surgical replacement of the aortic valve. We present an 88-year-old man who experienced periodic episodes of pre-syncope following aortic valve replacement. The underlying cause was identified as LVOTO resulting from elongated mitral valve leaflets. The diagnosis was established using stress echocardiography, which detected transient LVOTO with moderate rise in heart rate. The medical approach involved administering beta-blockers and optimising hydration consumption. The patient's symptoms and quality of life showed considerable improvement during the six-month follow-up period. Timely identification and intervention are essential in managing left ventricular outflow tract obstruction (LVOTO) after aortic valve replacement, to mitigate the risk of potential adverse cardiac events.
