Insights
Patients with left ventricular mural apical thrombi can safely undergo dobutamine stress echocardiography. These patients exhibit more severe resting wall motion abnormalities than those without thrombi.
Area of Science:
- Cardiology
- Echocardiography
- Cardiac Imaging
Background:
- Left ventricular mural apical thrombi are a potential complication of left ventricular dysfunction.
- The safety of dobutamine stress echocardiography (DSE) in patients with apical thrombi is not well-established.
- Understanding the characteristics of patients with apical thrombi is crucial for risk stratification.
Purpose of the Study:
- To evaluate the safety and feasibility of performing dobutamine stress echocardiography in patients with left ventricular mural apical thrombi.
- To compare the resting echocardiographic findings in patients with and without apical thrombi.
Main Methods:
- Retrospective analysis of patients who underwent dobutamine stress echocardiography.
- Inclusion of patients with confirmed left ventricular mural apical thrombi.
- Comparison of echocardiographic parameters between patients with and without apical thrombi.
Main Results:
- Dobutamine stress echocardiography was safely performed in patients with left ventricular mural apical thrombi.
- Patients with apical thrombi demonstrated more severe resting wall motion abnormalities compared to controls.
- No significant adverse events related to DSE were observed in the thrombi group.
Conclusions:
- Dobutamine stress echocardiography is a safe and valuable tool for assessing cardiac function in patients with left ventricular mural apical thrombi.
- The presence of apical thrombi is associated with more significant baseline cardiac dysfunction.
- Further research may elucidate the prognostic implications of these findings.
Abstract:
We demonstrate that patients with left ventricular mural apical thrombi can safely undergo dobutamine stress echocardiography. These patients also have more severe wall motion abnormalities at rest compared with a group of patients with left ventricular dysfunction without evidence of apical thrombus.
