Overview
On cardiac ultrasound, myxoma is characterized by the presence of a heterogeneous pedunculated mass that is commonly located in the left atrium. Cardiac myxomas appear as hyperechogenic lesions with a well-defined stalk. Moreover, echocardiography can be useful to assess the mobility of the tumor, as it often protrudes through valve flaps. Echocardiography is useful to evaluate the function identification and evaluation of cardiac myxomas. As an imaging modality, two-dimensional echocardiography is often coupled with other testing modalities (such as, Doppler echocardiography) to detect vascular abnormalities that frequently occur in cardiac myxomas. [1]
Echocardiography
Echocardiography is useful to evaluate tumor mobility on of cardiac myxoma, as it often protrudes through valve flaps. As a test modality, two-dimensional echocardiography is often coupled with other modalities (such as, Doppler echocardiography) to detect vascular abnormalities that frequently occur in cardiac myxomas. [1]
Transthoracic echocardiography
Transthoracic echocardiography(TT)is characterized by real-time imaging and can demonstrate tumor mobility and distensibility in cardiac myxoma. In addition, this imaging study is noninvasive, and characterizes heart morphology in a variety of imaging planes. It also provides a large amount of functional information. Transthoracic echocardiography is mainly limited by the available imaging window, which mainly depends on operator experience.[2]
Transesophageal echocardiography
Transesophageal echocardiography (TEE)is an invasive imaging technique, it may be helpful in the evaluation of extracardiac structures, such as the descending aorta and pulmonary veins. Unlike, transthoracic echocardiography there is no limitation to the acoustic window, better image resolution is often reached. Findings on cardiac myxomas, such as compression of cardiac structures can be better identified by TEE.[3]
Doppler ultrasound
A hallmark feature of Doppler is measuring velocity and chamber pressures.
Gallery
| Imaging Technique | Features | Description | Advantages | Limitations |
|---|---|---|---|---|
| Two- or three-dimensional echocardiography | Echocardiography is usually the initial modality used for identification and evaluation of cardiac myxomas |
|
|
|
| MRI | Evaluation of cardiac masses and is of greatest value when echocardiographic findings are suboptimal or when the lesion has an atypical location or appearance |
|
|
|
| CT | CT can be used to accurately image the heart and surrounding mediastinum |
|
|
|
| Angiography | Coronary angiography may be helpful to detect vascular supply of the tumor by the coronary arteries |
|
|
|
| Chest x-ray | Chest x-ray has no particular findings associated with cardiac myxoma |
