Subvalvular aortic stenosis associated with valvular aortic regurgitation in young child

Left Ventricular Outflow Tract Obstruction

“…However, valvar aortic stenosis with associated left ventricular hypertrophy may also be present [136]. Subvalvar aortic stenosis may also be observed in the context of aortic valve insufficiency [137]. Turbulent flow created by the fixed anatomic obstruction is believed to be responsible for gradual thickening of the aortic valve leaflets which may, in turn, contribute to the development of aortic valve insufficiency [134,138].…”

Transthoracic echocardiography of ruptured chorda tendinea

“…The discovery of a left ventricular outflow tract obstruction [3][4][5] by a mitral mass also obliges the clinician to perform a differential diagnosis including vegetations [6] versus rupture of the chordae tendineae [7] and its assessment also presents important clinical implications. Echocardiographic diagnosis of rupture of the chordae tendineae may be difficult to make.…”
