Key result
Cleft anterior leaflet repair without chordal resection is linked to ~88% freedom from MR.
Why the study?
Does surgical repair of the cleft anterior leaflet without resection of subjacent chordae tendineae result in a competent mitral valve in patients with ostium primum defect and cleft mitral valve?
Population
8 patients with ostium primum defect and cleft mitral valve

Chordal-sparing repair may be feasible in ostium primum defects; leaves open durability and generalizability beyond this small series.

Does surgical repair of the cleft anterior leaflet without resection of subjacent chordae tendineae result in a competent mitral valve in patients with ostium primum defect and cleft mitral valve?
Surgical repair of the cleft anterior leaflet without resection of subjacent chordae tendineae in ostium primum defect usually results in a competent mitral valve despite the presence of apical systolic murmurs.
Griffiths et al. (1969) conducted an observational in Ostium primum defect and cleft mitral valve (n=8). Surgical repair of the cleft anterior leaflet without resection of subjacent chordae tendineae was evaluated on Mitral regurgitation detected by pulmonary wedge pressure and left ventricular angiography. Surgical repair of the cleft anterior leaflet without resection of subjacent chordae tendineae resulted in a competent mitral valve, with no mitral regurgitation detected in 7 of 8 patients.
