Here we present the outcome of surgical treatment of 2 identical twins with mitral valve regurgitation (MR) and left ventricular (LV) dilatation.
Clinical Summary
A 52-year-old asymptomatic man (patient 1) presented with a newly detected cardiac murmur at a routine check-up. Further evaluation revealed a large (III-IV/IV) MR and LV dilatation (LV end-diastolic diameter [LVEDD] and LV end-systolic diameter [LVESD] of 62 and 38 mm, respectively). The LV function was preserved, with en ejection fraction (EF) of 60%. During cardiopulmonary bypass, a large posterior leaflet prolapse with chordal rupture was noted. A quadrangular resection of the P2 segment was performed combined with a sliding plasty and application of a 34-mm Carpentier-Edwards anuloplasty ring. The postoperative course was uneventful, and at 12 months' follow-up, there was a trace (0-I/IV) of MR, the LVEDD was reduced to 50 mm, the LVESD was reduced to 36 mm,
