“…In this entity, the identification of an additional papillary muscle aids in diagnosis ( 13 ). True, isolated AMVL clefts (not related to atrio-ventricular septal defects) are a rare finding ( 14 , 15 ), but due to an absence of anatomical scallops of the AMVL, these entities are not confused with inter-scallop separations and readily identified as congenital abnormalities.…”

Inter-scallop separations of the posterior leaflet of the mitral valve: an important cause of ‘pathological’ mitral regurgitation in rheumatic heart disease screening

SummaryThe 2012 World Heart Federation (WHF) criteria for echocardiographic diagnosis of rheumatic heart disease (RHD) identify that the finding of ‘pathological’ mitral regurgitation (MR) in a screened individual increases the likelihood of detecting underlying RHD. Cases of isolated ‘pathological MR’ are thus identified as ‘borderline RHD’. A large-scale echocardiographic screening program (Echo in Africa) in South Africa has identified that inter-scallop separations of the posterior mitral valve leaflet (PMVL) can give rise to ‘pathological’ MR. The authors propose that this entity in isolation should be identified and excluded from the WHF ‘borderline RHD’ category. In this case report, we present two examples of ‘pathological’ MR related to inter-scallop separation from the Echo in Africa image database. We further provide screening tips for the accurate identification of this entity.

IntroductionThe anterior mitral leaflet cleft is an unusual congenital lesion most often encountered in association with other congenital heart defects. The isolated anterior leaflet cleft is quite a rare anomaly and is usually cause of mitral valve regurgitation. The importance of the lesion is that it is often correctable. When feasible, cleft suture and, eventually, annuloplasty are preferable to valve replacement. Echocardiography is the first choice technique in the evaluation of mitral valve disease, providing useful information about valve anatomy and hemodynamic parameters.Case presentationWe present a case of an isolated anterior mitral leaflet cleft producing moderate-severe mitral regurgitation correctly identified by echocardiography and successfully surgically corrected.ConclusionIsolated cleft is a rare aberration, that has to be known in order to be diagnosed. Transthoracic and transesophageal echocardiography is the most useful non invasive technique for cleft diagnosis and to indicate the right surgical correction.

“…Also, recent advances in transducer technology have permitted the acquisition of high-resolution images and abnormalities that were once only diagnosed during surgery are nowadays diagnosed before surgery, such is the case of clefts and cleft-like indentations in the leaflets. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] While the accuracy of three-dimensional echocardiography in the diagnosis of left atrioventricular valve leaflets anomalies has been established in several studies comparing the preoperative diagnosis and intra-operative findings, there is some pitfalls in three-dimensional echocardiography that should be minded when reporting gaps in valve leaflets such as echo dropouts (annular calcification, improper gain) or oblique imaging planes creating the impression of a fissure not actually present. 1,16,19…”

A rare case series of mitral valve clefts diagnosed by 3D echocardiography and mini‐review of the literature

Mitral valve cleft is a rare entity. However, it must be recognized as a differential mechanism for mitral valve regurgitation. 3D transesophageal echocardiography plays an essential role in the evaluation of single and multiple mitral valve clefts, improving morphological and functional assessment of the valve, with potential implications on surgical planning. The authors present four rare cases of mitral valve cleft presenting during adulthood, followed by a mini‐review about the role of 3D echocardiography, as well as its pitfalls, in the assessment of this complex congenital mitral valve disease.

Isolated cleft of the anterior mitral valve leaflet

Abstract: Isolated anterior mitral leaflet cleft (not associated with atrio-ventricular septal defect) is a rare cause of congenital mitral regurgitation, and the treatment consists of direct suturing of the cleft. We present a clinical case with this entity.
