چکیده
Accessory mitral valve tissue is a rare congenital malformation. It can be found isolated or in combination with other cardiac anomalies and is usually detected in early childhood. We describe the case of a 74-year-old asymptomatic patient who was referred to our clinic for the evaluation of a heart murmur.

Accessory mitral valve tissue is a rare congenital malformation that has been reported in the literature in approximately 130 cases. This condition could be found isolated or in combination with other cardiac anomalies and is usually diagnosed in childhood. It is in differential diagnosis with other cardiac masses as tumors or vegetations. In this article a 27 year old asymptomatic female is p...
متن کاملA Rare Morphological Variant Accessory Posterolateral Cusp of Mitral Valve with Accessory Papillary Muscle in Left Ventricle in An Adult Cadaver in Middle East-A Case Report
Various cases of accessory leaflets of mitral valve or tissue around the opening have been reported in the past. In some cases they were the main etiological factor for sub aortic stenosis or regurgitation. Here we report a rare finding of accessory posterolateral cusp of mitral valve with accessory papillary muscle in left ventricle of an adult male cadaver. Such variation has not been reporte...
متن کاملAsymptomatic Accessory Mitral Valve Tissue Diagnosed by Echocardiography
A 19-year-old male patient was presented with a complaint of palpitation. His physical examination and 12-lead electrocardiogram were normal. Transthoracic echocardiography revealed a mobile, chord-like structure, attached to the anterior papillary muscle and ventricular surface of the anterior mitral leaflet moving in the systole into the left ventricular outflow tract (arrow) (Fig. 1). There ...
متن کاملRole of echocardiography in the diagnosis and surgical management of accessory mitral valve tissue causing left ventricular outflow tract obstruction.
We report an unusual case of left ventricular outflow tract obstruction caused by accessory mitral valve tissue. This case illustrates the importance of transthoracic echocardiography in preoperative evaluation and the usefulness of transesophageal echocardiography for intraoperative assessment. If the accessory mitral valve has no functional significance it may be surgically excised, thereby r...
متن کاملAccessory mitral valve tissue causing severe left ventricular outflow tract obstruction in a post-Senning patient with transposition of the great arteries
Accessory mitral valve tissue is a rare congenital anomaly associated with congenital cardiac defects and is usually detected in the first decade of life. We describe the case of an 18-year old post-Senning asymptomatic patient who was found to have accessory mitral valve tissue on transthoracic echocardiography producing severe left ventricular outflow tract obstruction.
متن کاملAccessory mitral valve tissue causing left ventricular outflow obstruction (two-dimensional echocardiographic diagnosis and surgical approach).
Accessory mitral valve tissue, a rare cause of left ventricular outflow tract obstruction, can be difficult to diagnose preoperatively and confusing even at surgery. The reported case illustrates how preoperative evaluation can be made using two-dimensional echocardiography combined with Doppler flow analysis. The intraoperative technique for removing the accessory tissue without causing damage...
