1 Novel Annular and Subvalvular Enlargement in Congenital Mitral Valve Replacement 
Nels D. Carroll, MD, Kevin M. Beers, DO, Elaine M. Maldonado, MD, John H. Calhoon, MD, S. Adil Husain, MD  The Annals of Thoracic Surgery  Volume 102, Issue 3, Pages e277-e279 (September 2016) DOI: /j.athoracsur Copyright © 2016 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Transesophageal echocardiogram (TEE) performed before mitral valve replacement demonstrates thickened, restrictive leaflets resulting in moderate to severe mitral regurgitation.

3 Fig 2 (A) Computer rendering demonstrates an external view (left) of border stitches demarcating a free zone containing ventriculotomy; an internal left atrial view (right) through the mitral annulus after removal of leaflets shows approximate border stitch placement. (B) Computer rendering shows left posterior oblique view of the heart after placement of a ventriculoplasty patch.

4 Fig 3 (A) Postoperative transesophageal echocardiogram (TEE) after mitral valve replacement demonstrates a well-seated mechanical prosthesis free of leaflet impingement. (B) TEE Doppler waveform evaluation across the mitral valve performed at 5-year follow-up demonstrates an appropriate pressure gradient and trace mitral regurgitation. (Env. T1 = envelope time interval; HR = heart rate; Pmax = maximum pressure; Pmean = mean pressure; Vmax = maximum volume; Vmean = mean volume; VTI = velocity time integral.)
