ANULOPLASTIA MITRAL
Consideraciones prequirúrgicas
• Ecocardiografia prequirurgica para el análisis del
  mecanismo de insuficiencia.
• La selección del paciente se hace en base a:
  – Etiología de la regurgitación.
  – Morfología de la válvula, condiciones del aparato
    subvalvular y características del VI.
  – Tipo funcional de la regurgitación.

           Berlin.
Objetivos de la Cirugía
• Efecto durable de la reparación.
• Evitar generar una estenosis valvular.
• Permitir una amplia y optima coaptación de los
  velos de la válvula mitral.
• El resultado de la reparación debe ser objetivado
  inmediatamente después de despinzar aorta.

Anuloplastia Mitral
          • The      GeoForm       ring    is
            geometrically designed to treat
            mitral regurgitation caused by
            the enlargement of the left
            ventricle.        Anteroposterior
            distance of the mitral annulus is
            reduced and the P2 zone is
            elevated in the ring.
Anuloplastia Mitral




•   A novel annuloplasty ring design, Myxo-ETlogix (Edwards), is also aimed at
    prevention of systolic anterior motion (SAM) in patients with myxomatous leaflet
    degeneration (Barlow’s disease). This ring has a significantly longer
    anteroposterior diameter and saddle-like elevation in the area of P2.

Anuloplastia semicircular (Burr)




•   This suture annuloplasty technique is simple, fast and inexpensive, preserves
    flexibility of the annulus, and durability of the result is comparable to that of ring
    implantations.

Plicatura anular (Wooler)




•   Wooler repair is presently justified in occasional situations only (long duration of
    cardiopulmonary bypass in complex procedures, elderly patients, difficult exposure
    of mitral valve due to deep chest, in reoperations, etc.).

Anuloplastia Mitral Adjustable annuloplasty ring St. Jude Medical–Attune and Puig–Massana–Shiley (top) • This ring offers symmetrical adjustability by pulling both purse-string-suture ends equally or asymmetrical adjustability by pulling one purse-string-suture end more than the other. 1.

  • 22. Anuloplastia Mitral • The GeoForm ring is geometrically designed to treat mitral regurgitation caused by the enlargement of the left ventricle. Anteroposterior distance of the mitral annulus is reduced and the P2 zone is elevated in the ring.
  • 23. Anuloplastia Mitral • A novel annuloplasty ring design, Myxo-ETlogix (Edwards), is also aimed at prevention of systolic anterior motion (SAM) in patients with myxomatous leaflet degeneration (Barlow’s disease). This ring has a significantly longer anteroposterior diameter and saddle-like elevation in the area of P2. 1. McCarthy PM, McGee EC, Rigolin VH et al.
