(B) Mitral valve repair, showing eccentric commissural annuloplasty, coaptation stitch of leaflets, and papillary muscle rotation and pull toward the apex. (C) Pledget-supported over-and-over suture of the left ventricle. (APM = anterior papillary muscle; PML = posterior mitral leaflet; PPM = posterior papillary muscle.)

Fig 4 Cardiac index (CI) and pulmonary capillary wedge pressure (PCWP), before, during, and after partial left ventriculectomy. Increase in CI after partial left ventriculectomy was noted with further improvement during follow-up. PCWP decreased initially, but returned to baseline values at follow-up. (Base = baseline; intraop = intraoperative; Mo = months; post = postoperatively; W = weeks; ∗p < 0.05; †p < 0.01; ∗∗p < 0.0001.)
