Techniques and results of ventricular aneurysmectomy with emphasis on anteroseptal repair
Insights
Ventricular aneurysmectomy, particularly anteroseptal repair, improves survival rates in patients with anterior aneurysms. Preoperative and postoperative coronary artery assessment significantly impacts outcomes.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Outcomes
- Medical Imaging in Cardiology
Background:
- Ventricular aneurysms, often anterior, pose significant risks to cardiac function and patient survival.
- Surgical intervention, including ventricular aneurysmectomy, is a critical consideration for managing these conditions.
- Optimizing surgical strategies requires understanding the interplay between aneurysm characteristics, coronary artery disease, and patient outcomes.
Purpose of the Study:
- To evaluate the long-term outcomes of ventricular aneurysmectomy in a large patient cohort.
- To correlate preoperative radiographic findings and coronary anatomy with hospital mortality and survival rates.
- To develop a predictive scoring system for patient prognosis following surgical repair.
Main Methods:
- Review of an 8-year experience with 170 patients undergoing ventricular aneurysmectomy.
- Analysis of preoperative left ventriculograms and coronary arteriograms, with a scoring system applied.
- Development of a postoperative coronary artery score based on preoperative anatomy and bypass procedures.
- Correlation of radiographic scores with hospital mortality and long-term survival data.
Main Results:
- Anteroseptal repair was performed in 90% of patients with anterior aneurysms.
- Both ventriculogram and postoperative coronary artery scores significantly impacted mortality and survival.
- Preoperative coronary disease severity had limited predictive value; recent myocardial infarction did not preclude good results.
- Aggressive surgical approaches were validated, even in subsets with poor prognostic indicators.
Conclusions:
- Ventricular aneurysmectomy, especially anteroseptal repair for anterior aneurysms, yields optimal results.
- Comprehensive coronary artery bypass grafting is recommended for all suitable vessels.
- Detailed preoperative anatomical and functional assessment is crucial for accurate prognosis and optimal therapeutic strategy selection.
Abstract:
We have reviewed an 8 year experience with ventricular aneurysmectomy in 170 patients. Ninety percent had anterior aneurysms and underwent "anteroseptal repair" with exclusion of nonfunctioning septal myocardium. Preoperative left ventriculograms and coronary arteriograms were studied and "scored," and the hospital mortality and long-term survival rates for various subsets of the group were correlated with their radiographic data. A postoperative score for the coronary arteries was developed according to the preoperative anatomy and the vessels bypassed. Both the ventriculogram score and the postoperative coronary score had significant effects on both hospital mortality and long-term survival rates. The severity of preoperative coronary disease had minimal predictive value. Recent myocardial infarction did not preclude a good result. The value of an aggressive surgical approach to patients with ventricular aneurysm was confirmed even for certain subsets with indicators suggestive of poor prognosis. Anteroseptal repair appears to give optimal results for the typical "anterior" aneurysm. All suitable coronary arteries should be bypassed. Attention to the details of preoperative anatomy and function allows the most accurate prediction of prognosis and dictates the optimal therapeutic approach.
