Left ventricular outflow tract obstruction from mitral prosthesis.
A case of left ventricular outflow tract obstruction six years following mitral valve replacement is presented. Clinical features, echocardiographic and angiographic studies preoperatively all suggested aortic valve disease. The diagnosis of left ventricular outflow tract obstruction by the strut of the mitral prosthesis was made intraoperatively. Enlargement of the aortic root and aortic valve replacement resulted in good symptomatic and echocardiographic improvement.
