[Computerized processing of two-dimensional echo-cardiograms: its application for quantitating left ventricular...

Area of Science:

• Cardiology
• Medical Imaging
• Computational Biology

Context:

• Assessing left ventricular regional contractility is crucial for diagnosing and managing myocardial infarction.
• Traditional methods for evaluating contractility can be subjective and time-consuming.
• Advancements in digital image processing offer potential for more objective and efficient assessments.

Purpose:

• To develop and validate a novel computer-based digital image processing method for quantitating left ventricular regional contractility from two-dimensional echocardiograms.
• To compare the automated edge detection and segmentation of the left ventricle with manual tracing.
• To evaluate the method's efficacy in differentiating contractility in patients with healed myocardial infarction versus normal controls.

Summary:

• A new practical method for computer digital image processing of two-dimensional echocardiograms was developed.
• The method automatically detects endocardial and epicardial edges, divides the left ventricle into eight segments, and calculates regional contractility parameters.
• This automated analysis demonstrated significantly reduced contractility in the infarcted left ventricular walls of myocardial infarction patients compared to controls.

Impact:

• Provides an objective and automated tool for assessing left ventricular regional contractility, potentially improving the diagnosis and management of myocardial infarction.
• Offers a practical application of advanced digital image processing in clinical cardiology.
• Facilitates quantitative evaluation of cardiac function, aiding in patient stratification and treatment planning.
