Insights
Contrast echocardiography accurately diagnosed a left ventricular diverticulum in an 81-year-old woman. This imaging technique clearly visualized intracardiac blood flow and myocardial perfusion, confirming the diagnosis.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Left ventricular diverticulum is a rare cardiac anomaly.
- Accurate diagnosis is crucial for patient management.
Observation:
- An 81-year-old woman presented with a suspected left ventricular diverticulum.
- Myocardial contrast echocardiography was performed for diagnosis.
Findings:
- Pulsed Doppler revealed biphasic ejection flow waveforms at the diverticulum ostium.
- Harmonic power Doppler showed similar acoustic properties of the diverticulum wall to the septum.
- Contrast echocardiography clearly evaluated intracardiac blood flow and myocardial perfusion.
Implications:
- Contrast echocardiography is a valuable tool for diagnosing left ventricular diverticulum.
- This technique aids in understanding blood flow dynamics in cardiac anomalies.
Abstract:
A case of an 81-year-old woman with a left ventricular diverticulum who underwent myocardial contrast echocardiography is reported. After administration of the contrast agent, a pulsed Doppler flow measurement clearly revealed the biphasic waveform of the ejection flow in the pre-systolic and systolic phase at the ostium of the diverticular cavity. A harmonic power Doppler image showed that part of the diverticulum wall had similar acoustic properties to the ventricular septal wall. Intracardiac blood flow and myocardial perfusion could be clearly evaluated and a ventricular diverticulum was correctly diagnosed using contrast echocardiography.
