This study presents a safe technique for reducing giant left atrium volume using triangular resections. The procedure successfully reduced atrial size, improving patient outcomes after mitral valve replacement.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Cardiac Surgery

Background:

  • Giant left atrium (GLA) presents significant surgical challenges due to its size and mass effect.
  • Surgical intervention for GLA often requires complex techniques to manage atrial volume and associated pathologies.

Observation:

  • A 56-year-old patient with a giant left atrium (18 x 20 x 17 cm) underwent redo mitral valve replacement.
  • The enlarged atrium caused compression of adjacent thoracic organs.

Findings:

  • A novel technique involving triangular resections of the atrial wall was employed for left atrial volume reduction.
  • Mitral valve replacement was successfully performed using a mechanical prosthesis.
  • Postoperative follow-up showed an uneventful recovery with a reduced left atrial diameter of 11.2 cm.

Implications:

  • This technique offers a safe and reproducible method for managing giant left atrium.
  • Successful volume reduction can alleviate mass effect and improve patient quality of life.
  • Further studies are warranted to evaluate the long-term efficacy and applicability of this surgical approach.
