Surgical treatment of papillary muscle rupture
Abstract:
Between 1971 and 1979, 16 patients underwent mitral valve replacement for papillary muscle rupture after infarction. Nine of these patients were operated on within 3 days of papillary muscle rupture. Eight patients had low cardiac output syndrome prior to operation. Six patients had concomitant coronary artery bypass, and 1 patient had resection of an associated left ventricular aneurysm. There were 3 operative deaths (19% mortality). Surviving patients have been followed for a total of 49 patient-years. There have been 2 late deaths, each a result of coronary artery disease. Six of the 11 surviving patients are asymptomatic; the others are in New York Heart Association Functional Class II or III. The actuarial 5-year survival was 75%. These data support the concept that an aggressive attitude should be taken toward early diagnosis and surgical treatment of postinfarction papillary muscle rupture.
Insights
Early surgical treatment for post-infarction papillary muscle rupture can improve survival. Aggressive diagnosis and intervention are recommended for patients experiencing this serious complication following a heart attack.
Area of Science:
- Cardiology
- Cardiac Surgery
- Cardiovascular Research
Background:
- Post-infarction papillary muscle rupture is a rare but life-threatening complication.
- Prompt diagnosis and surgical intervention are critical for patient outcomes.
Purpose of the Study:
- To evaluate the outcomes of mitral valve replacement in patients with post-infarction papillary muscle rupture.
- To assess the impact of early surgical intervention on survival rates.
Main Methods:
- Retrospective review of 16 patients undergoing mitral valve replacement for papillary muscle rupture between 1971 and 1979.
- Analysis of operative mortality, long-term survival, and functional status.
Main Results:
- Operative mortality was 19% (3 deaths).
- Actuarial 5-year survival was 75%.
- Six of 11 surviving patients were asymptomatic; others had functional class II or III status.
Conclusions:
- Early diagnosis and aggressive surgical treatment of post-infarction papillary muscle rupture are associated with improved survival.
- Mitral valve replacement is a viable option for managing this condition.
