Key result
Echocardiography successfully identified extensive tissue fibrosis, calcification, and stenosis of a stent-mounted aortic homograft in the mitral position, confirmed by pathologic findings.
Case Report
Echocardiography can be used to accurately diagnose calcific stenosis in a stented aortic homograft placed in the mitral position.
May support echocardiography for rare mitral homograft stenosis; hypothesis-generating and requires validation in larger cohorts.
Echocardiography was used to diagnose a calcified and stenotic stent‐mounted aortic homograft in the mitral position. Poorly moving intense echoes from the valve leaflets suggested extensive tissue fibrosis and calcification. Markedly reduced diastolic posterior movement of the echoes returning from the stent implied restriction to ventricular filling through a stenotic mitral valve. Hemodynamic, angiographic, and pathologic findings confirmed this ultrasonic diagnosis. The ultrasonic appearance of the normally functioning stented tissue valve in the mitral position and the technique for recording this bioprosthesis are described.

Horowitz et al. (1974) conducted a case report in Calcific stenosis of a stented aortic homograft in the mitral position. Echocardiography was evaluated on Diagnosis of calcified and stenotic stent-mounted aortic homograft. Echocardiography successfully identified extensive tissue fibrosis, calcification, and stenosis of a stent-mounted aortic homograft in the mitral position, confirmed by pathologic findings.
