Prognostic considerations in the management of left ventricular aneurysms
Insights
Left ventricular aneurysm (LVA) resection is a viable surgical option. Preoperative cardiac index and septal motion on ventriculogram are key prognostic indicators for patient outcomes.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Imaging
Background:
- Left ventricular aneurysm (LVA) is a serious cardiac condition.
- Surgical intervention for LVA aims to improve patient survival and quality of life.
- Identifying reliable prognostic factors is crucial for patient selection in LVA surgery.
Purpose of the Study:
- To evaluate the long-term outcomes of left ventricular aneurysm resection combined with coronary artery bypass grafting.
- To identify preoperative predictors of successful surgical outcomes in patients with LVA.
- To determine the safety and efficacy of LVA resection in relation to myocardial revascularization.
Main Methods:
- Retrospective review of cardiac catheterization data from 60 patients who underwent LVA resection and coronary artery bypass.
- Analysis of preoperative cardiac index and septal motion (assessed via left anterior oblique ventriculogram) as prognostic indicators.
- Comparison of operative and late mortality rates between LVA resection and standard myocardial revascularization.
Main Results:
- Operative and late mortality rates were 3.3% and 8.3%, respectively.
- Preoperative cardiac index and the presence of septal motion were significant prognostic factors.
- Patients lacking septal motion demonstrated no survivors, leading to their exclusion from surgical candidacy.
- LVA resection in patients with septal motion showed comparable risks to myocardial revascularization alone.
Conclusions:
- Left ventricular aneurysm resection with coronary artery bypass is associated with acceptable mortality rates.
- Preoperative septal motion is a critical determinant for surgical candidacy in LVA patients.
- Patients with preserved septal motion can safely undergo LVA resection, with risks similar to standard bypass surgery.
- Cardiac index is a valuable indicator for predicting postoperative outcomes in LVA patients.
Abstract:
This report summarizes a four-year experience with 60 patients who had left ventricular aneurysm (LVA) resection and bypass of all significantly diseased coronary arteries, with an operative and late mortality of 3.3 and 8.3%, respectively. Their cardiac catheterizations were reviewed, and the only values that seemed to reflect prognosis were preoperative cardiac index and the presence of absence of septal motion. The lower the cardiac index, the less likely the patient was to do well postoperatively. There were now survivors who had lacked septal motion by left anterior oblique ventriculogram. Patients without septal motion are therefore no longer considered surgical candidates. If septal motion is present, resection of LVA carries no more risk than myocardial revascularization without LVA.
