Ventricular aneurysm: cross-sectional echocardiographic approach

Area of Science:

• Cardiology
• Medical Imaging
• Echocardiography

Background:

• Current angiographic methods for assessing ventricular function in patients with ventricular aneurysm lack prognostic accuracy.
• Ventricular aneurysm diagnosis and management require better tools to evaluate residual myocardial function.

Purpose of the Study:

• To introduce and validate a novel echocardiographic technique for quantifying residual myocardium in patients with left ventricular aneurysm.
• To assess the prognostic value of this new echocardiographic index in predicting clinical outcomes.

Main Methods:

• Utilized cross-sectional echocardiography to visualize and calculate residual myocardium across all left ventricular walls.
• Correlated echocardiographic measurements with contrast angiography to establish accuracy (r = 0.97).
• Generated a residual myocardium index and analyzed its correlation with patient clinical status and outcomes.

Main Results:

• The echocardiographic technique provided information comparable to contrast angiography.
• The derived residual myocardium index showed a significant correlation with the patients' clinical condition.
• In medically treated patients, the index predicted 6-month mortality (p < 0.005).
• Preliminary data suggest good surgical outcomes in aneurysmectomy patients with a residual myocardium index >= 0.42.

Conclusions:

• Echocardiography offers a reliable method for assessing residual myocardium in ventricular aneurysm.
• The novel echocardiographic index is a valuable prognostic tool for medically managed patients.
• Further research is needed to define the optimal residual myocardium index for surgical intervention in aneurysmectomy.
