2.3. Surgical procedure
The technical details of the mitral valve repair procedure were
determined at the surgeon’s discretion according to the mitral
morphology. There were two approaches for the mitral valve: an incision
to the LA and an incision to the right atrium and atrial septum. The
techniques for leaflet repair were selected from a new chordal
replacement, leaflet resection (quadrangular or triangular leaflet
resection) and leaflet augmentation. A semi-rigid full ring or a
flexible band was implanted in all patients.
