Summary
Early resection of left ventricular aneurysms improves outcomes. This study reviews criteria, techniques, and results, advocating for timely surgical intervention to prevent decompensation and enhance survival.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery
- Thoracic Surgery
Background:
- Left ventricular aneurysms can lead to hemodynamic compromise and decompensation.
- Symptoms and natural history necessitate consideration of early surgical intervention.
Purpose of the Study:
- Define criteria for resectable left ventricular aneurysms.
- Review surgical techniques and outcomes for aneurysm repair.
- Advocate for early resection to improve patient prognosis.
Main Methods:
- Review of patient selection criteria for left ventricular aneurysm resection.
- Analysis of various surgical repair techniques, emphasizing modified linear closure.
- Evaluation of the impact of repair on mitral regurgitation and ischemic time.
Main Results:
- Modified linear closure allows repair before aortic cross-clamping, minimizing ischemic time.
- Aneurysm repair can positively influence concomitant mitral regurgitation.
- Low operative mortality and good symptomatic improvement are achievable.
Conclusions:
- Early left ventricular aneurysm resection is associated with improved outcomes.
- Proper patient selection and surgical technique are crucial for success.
- Excellent 5-year survival rates are reported following successful aneurysm repair.
