Summary
Giant left atrium (GLA) in mitral valve disease (MVD) patients did not increase surgical risk. This study found GLA did not significantly impact hospital or late mortality after mitral valve repair, suggesting plication may not always be necessary.
Area of Science:
- Cardiology
- Cardiac Surgery
- Thoracic Surgery
Background:
- Giant left atrium (GLA) associated with mitral valve disease (MVD) is considered a significant risk factor in mitral valve surgery.
- Reported mortality rates for MVD surgery range from 8% to 32%.
- Left atrial plication has been proposed to mitigate postoperative complications.
Purpose of the Study:
- To evaluate the impact of GLA on outcomes following mitral valve surgery.
- To determine if GLA is a significant risk factor in mitral valve repair (MVR).
- To assess the necessity of left atrial plication in MVD patients.
Main Methods:
- Retrospective review of 203 consecutive patients with MVD undergoing surgery between 1980 and 1986.
- Patients were divided into two groups: Group A (without GLA, n=165) and Group B (with GLA, n=38).
- Analysis of preoperative, intraoperative, and early/late postoperative courses.
Main Results:
- Hospital mortality was comparable between groups: 2.4% in Group A and 2.6% in Group B.
- Late mortality at a mean follow-up of 54 months was also similar: 4.3% in Group A and 5.4% in Group B.
- GLA was not found to be a significant risk factor affecting early or late outcomes in MVR.
Conclusions:
- Giant left atrium is not a significant risk factor in mitral valve repair.
- Outcomes in MVD patients with GLA are comparable to those without GLA.
- Left atrial plication may not be required in the absence of extracardiac compression signs.
