Abstract/OtherAbstract:
We present a case of a 27-year-old female with severe mitral regurgitation caused by a single long aberrant chorda tendinea. This chorda extended from the base of the right coronary cusp of the aortic valve, through the A2 scallop of the mitral valve, and attached to the dome of the left atrium. Initial transthoracic echocardiogram (TTE) demonstrated a mildly redundant anterior mitral leaflet with thickened leaflet tip and moderate eccentric, posteriorly directed mitral regurgitation. Repeat TTE revealed a chord-like structure attached to the midportion of the anterior mitral leaflet and extending to the left ventricular outflow tract. Transesophageal echocardiography (TEE) suggested two aberrant chordae tendineae tethering the A2 scallop on both the left atrial and left ventricular side. Patient underwent surgical resection of the aberrant chorda. During the excision of the chorda the structural integrity of the A2 scallop was compromised, necessitating mitral valve repair with excellent results. (Echocardiography, 2012; E1-E3).
