Summary
Surgical resection of ventricular aneurysms improved heart function and arrhythmias in most patients. Good outcomes were linked to preserved ejection fraction, smaller akinetic zones, and less coronary artery obstruction.
Area of Science:
- Cardiovascular Surgery
- Cardiac Imaging
- Interventional Cardiology
Context:
- Ventricular dyskinesia, often resulting from myocardial infarction, presents significant challenges in cardiac function.
- Aneurysmal dilation of the ventricle can lead to heart failure and ventricular arrhythmias.
- Surgical intervention is considered for refractory cases, but outcomes can be variable.
Purpose:
- To evaluate the cardiac function and surgical outcomes in patients with ventricular dyskinesia.
- To identify predictors of successful surgical intervention for ventricular aneurysms.
- To assess the impact of aneurysm resection on heart failure and arrhythmias.
Summary:
- This study analyzed 37 patients with ventricular dyskinesia who underwent aneurysm resection.
- Cardiac function was assessed using cineangiography, evaluating contraction amplitude, speed, and akinetic zone volume.
- Coronary artery obstruction was scored, and surgical outcomes were correlated with pre-operative parameters.
Impact:
- Aneurysm resection, particularly with aorto-coronary bypass grafting, significantly improved heart failure symptoms and reduced ventricular arrhythmias.
- Positive surgical outcomes were associated with an ejection fraction >0.40, dyskinetic area <40%, and coronary obstruction index <6.
- The findings provide valuable criteria for patient selection and surgical planning in ventricular aneurysm treatment.
