Fig. 4From: Posterior mitral annuloplasty for enhancing mitral leaflet coaptation: using a strip designed for placement in the posterior annulusPreoperative (a) and postoperative (b) computed tomographic study of a patient who underwent posterior mitral annuloplasty for mitral regurgitation secondary to annular dilation. a A preoperative sagittal view showed that the medial commissural annulus (white arrow) was placed in the plane between the anterior annulus (white arrowhead) and posterior annulus (white empty arrowhead). b The postoperative sagittal view showed that the hinged medial commissure (white arrow) was placed below the antero-posterior annular plane. AV: aortic valve; LA: left atrium; LV: left ventricle.Back to article page
