Intermittent malfunction of a mechanical valve prosthesis is a rare condition that carries serious clinical implications. It results from the periodic entrapment of a prosthetic disk in either an open or closed position leading to transient intravalvular regurgitation or obstruction to flow. The intermittent nature of the malfunction poses a diagnostic challenge, particularly in the era of digital echocardiography. In this manuscript, we describe the Doppler and two-dimensional echocardiographic findings in a patient with intermittent prosthetic mitral valve malfunction.

Abstract
Intermittent malfunction of a mechanical valve prosthesis is a rare condition that carries serious clinical implications. It results from the periodic entrapment of a prosthetic disk in either an open or closed position leading to transient intravalvular regurgitation or obstruction to flow. The intermittent nature of the malfunction poses a diagnostic challenge, particularly in the era of digital echocardiography. In this manuscript, we describe the Doppler and two-dimensional echocardiographic findings in a patient with intermittent prosthetic mitral valve malfunction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
