Left ventricular contrast echocardiography: role for evaluation of function and structure

Area of Science:

• Cardiovascular Imaging
• Echocardiography
• Medical Ultrasound

Background:

• Tissue harmonic imaging in echocardiography still results in poorly defined left ventricular (LV) endocardial borders in 10%-15% of patients.
• This limitation can lead to inaccurate assessment of LV function and necessitate additional, costly imaging modalities.

Purpose of the Study:

• To evaluate the role of second-generation contrast echocardiography agents in improving endocardial border definition and LV function assessment.
• To explore the utility of contrast agents in identifying LV masses and structural abnormalities.

Main Methods:

• Utilized second-generation contrast echocardiography agents (e.g., SonoVue) to enhance endocardial visualization.
• Assessed the impact of contrast agents on the accuracy and reproducibility of LV function evaluation.
• Examined the use of contrast echocardiography for characterizing LV masses and structures.

Main Results:

• Contrast agents significantly improve the clarity of endocardial borders, facilitating better LV function assessment.
• Enabled automated and qualitative LV function assessment, leading to more accurate and reproducible results.
• Demonstrated effectiveness in evaluating LV masses (thrombus, tumors) and defining structures (aneurysm, pseudoaneurysm, noncompaction, apical cardiomyopathy).

Conclusions:

• Contrast-enhanced echocardiography is crucial for accurate LV assessment, especially when standard imaging is suboptimal.
• These agents enhance diagnostic capabilities, potentially reducing healthcare costs by minimizing the need for alternative imaging.
• Contrast echocardiography offers significant advantages for evaluating LV structure, function, and pathology.
