Detection of left ventricular aneurysms by cross-sectional echocardiography
Insights
Real-time cross-sectional echocardiography effectively visualizes left ventricular aneurysms. This noninvasive method aids in detecting and locating ventricular aneurysms, offering a valuable diagnostic tool.
Area of Science:
- Cardiology
- Medical Imaging
- Echocardiography
Background:
- Left ventricular aneurysms are a serious complication of heart disease.
- Accurate detection and localization are crucial for patient management.
Purpose of the Study:
- To evaluate the utility of real-time cross-sectional echocardiography for detecting left ventricular aneurysms.
- To compare echocardiography with other noninvasive diagnostic methods.
Main Methods:
- Cross-sectional echocardiography was performed on 31 patients with confirmed left ventricular aneurysms.
- Ventricular shape and contraction patterns were compared with normal controls and patients with ventricular dysfunction.
- Physical examination, chest roentgenography, electrocardiography, and M-mode echocardiography were also assessed.
Main Results:
- Cross-sectional echocardiography successfully visualized the presence and location of left ventricular aneurysms.
- Minor discrepancies in aneurysm extent were noted in 4 patients due to limitations of either echocardiography or angiography.
- Echocardiography demonstrated utility in detecting ventricular aneurysms noninvasively.
Conclusions:
- Cross-sectional echocardiography is a valuable noninvasive tool for diagnosing left ventricular aneurysms.
- It provides detailed visualization of aneurysm presence and location.
- Further comparison with other methods confirms its diagnostic potential.
Abstract:
Real-time cross-sectional echocardiographic studies of the left ventricle were performed in 31 consecutive patients with angiographically proven left ventricular aneurysms (group I). In each of these patients the presence and location of the aneurysm was visualized by the cross-sectional echocardiography. In four patients discrepancy in the extent of the aneurysm was noted due either to failure of the cross-sectional technique to visualize the entire anterior wall of the ventricle (3) or failure of the single plane angiogram to adequately define the lateral extent of the aneurysm (1). Ventricular shape and contraction sequence in patients with aneurysms were compared with similar patterns in 20 patients with normal left ventricles (group II), and 20 patients with ischemic heart disease and localized ventricular dysfunction without aneurysm formation (group III). Other noninvasive methods for detecting aneurysms (including physical examination, chest roentgenography, electrocardiography, and M-mode echocardiography) were also evaluated in the aneurysm group. This report suggests that cross-sectional echocardiography is a useful method for detecting ventricular aneurysms noninvasively.
