Presentation
Exertional dyspnea, atypical chest pain and fatigue, especially during times of increased activity
Patient Data
Left ventricle: LVIDd=54mm, normal systolic function.
Aortic Valve: normal tri-leaflet aortic valve, non-calcified leaflets, sufficient opening, observation of a sub-aortic membrane, Vmax=2.9, PGmean=21mmhg, PGmax=35mmhg.
Moderate aortic regurgitation.
Case Discussion
This patient presented with exertional dyspnea, atypical chest pain and fatigue especially during times of increased activity.
Examination showed a palpable systolic thrill at the apex.
Auscultation revealed a systolic murmur along the left sternal border and S2 was audible.
Sub-aortic stenosis is one of the types of left ventricular outflow tract obstruction presented with a membrane just below the aortic valve which causes a fixed obstruction to the blood flow across the left ventricular outflow tract.
In our case, the sub-aortic stenosis was corrected with mini-sternotomy surgery and the patient was discharged without complications.
