    This study introduces a new quantitative analysis method for left ventricular aneurysms, aiding surgical decisions. The technique accurately assesses aneurysm size and remaining heart muscle function, crucial for predicting surgical outcomes.

    Area of Science:

    • Cardiology
    • Medical Imaging Analysis

    Background:

    • Left ventricular aneurysms pose significant risks.
    • Accurate quantitative analysis is vital for surgical planning.

    Purpose of the Study:

    • To present a novel quantitative method for analyzing left ventricular aneurysms.
    • To evaluate the functional impact of aneurysms on remaining myocardium.
    • To aid in surgical decision-making for patients with ventricular aneurysms.

    Main Methods:

    • Quantitative analysis of left ventricular angiography in 22 patients.
    • Determining the demarcation between aneurysm (A) and remaining myocardium (RM) using changes in shortening.
    • Calculating volumes and ejection fractions of the left ventricle, aneurysm, and remaining myocardium.
    • Comparing results between patients with and without heart failure.

    Main Results:

    • The new method accurately delineated aneurysms and quantified myocardial function.
    • Aneurysm size was significantly larger in patients with heart failure (P<0.01).
    • Function of the remaining myocardium was not significantly different between groups, suggesting potential for favorable surgical outcomes.
    • Preoperative and postoperative volumes showed good correlation, validating the method.

    Conclusions:

    • The developed method provides accurate quantitative analysis of left ventricular aneurysms.
    • Findings suggest that surgical resection may yield favorable results even in patients with heart failure.
    • This quantitative approach improves patient evaluation for surgical intervention.
