Timely identification using stress echocardiography and medical management with beta-blockers and hydration can effectively treat transient LVOTO caused by elongated mitral leaflets after surgical aortic valve replacement.
May prompt stress echocardiography for post-AVR syncope; leaves open whether mitral leaflet length alters pre-operative planning.
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.

Davies et al. (2024) conducted a case report in Left ventricular outflow obstruction (LVOTO) post-aortic valve replacement (n=1). Beta-blockers and optimized hydration was evaluated on Symptom and quality of life improvement. Beta-blockers and optimized hydration considerably improved symptoms and quality of life in an 88-year-old man with left ventricular outflow obstruction following aortic valve replacement.
