On cardiac ultrasound images are often seen structures in the heart or pericardium that can be mistaken for tumors or other diseases. Below an overview of normal cardiac structures that are common mistaken for other structures.
Location of structures that can be visualized in the heart
| Location | Structures |
|---|---|
| Left atrium | Coumadin ridge, ridge between Left pulmonary vein and LAA |
| Atrial suture line after heart transplant | |
| Twisted LAA | |
| Atrial septal aneurysm | |
| Lipomatous hypertrophy of the atrial septum | |
| Twisted descending aorta | |
| Right atrium | Christa terminalis (ridge between IVC and SVC). |
| Congenital valve residues (Eustachian valve, Chiari network, Thebesian band). | |
| Trabeculae in RAA. | |
| Atrial suture line after heart transplantation. | |
| Catheter, lines, pacemaker wires | |
| Left ventricle | Papillary muscles. |
| False tendon. | |
| Prominent trabeculae. | |
| High intentity transient spots at prostethic valves | |
| Right ventricle | Moderator Band. |
| Papillary muscles. | |
| Catheter, pacemaker wires | |
| Aortic valve | Noduli of Arantius |
| Lambl's excrescences | |
| Mitral valve | Redundant chorda |
| Redundant valve tissue | |
| Pericardium | Epicardial fat |
| Fibrinous debris in chronic pericardial effusion |
