A transoesophageal echocardiogram (TOE) typically takes about 20 to 30 minutes to perform. This diagnostic procedure provides a detailed view of your heart's structure and function.
Understanding the Procedure Duration
The actual time spent with the ultrasound probe inside your esophagus is relatively short, usually falling within the 20 to 30-minute window. However, the overall appointment might be longer due to preparation and recovery time.
- Preparation: Before the procedure begins, you will need to undress and change into a hospital gown. If you wear dentures or dental plates, you will be asked to remove them. This preparation helps ensure clear imaging and patient comfort.
- Sedation: You will usually be given a sedative to help you relax and a local anesthetic to numb your throat. These take a few minutes to take effect.
- Procedure: A doctor or a sonographer (a technician specifically trained to use ultrasound equipment) will guide a thin, flexible tube with an ultrasound probe on its end down your throat into your esophagus. The proximity of the esophagus to the heart allows for very clear images.
- Recovery: After the procedure, you'll need a short period for the effects of the sedative to wear off before you can go home.
What to Expect During a Transoesophageal Echocardiogram
Here's a brief overview of what the process typically involves:
| Stage | Estimated Time | Details |
|---|---|---|
| Preparation | 10-15 minutes | Changing into a gown, removing dental prosthetics, receiving throat numbing spray and sedation. |
| Procedure | 20-30 minutes | Insertion of the probe, capturing images of the heart. |
| Recovery | 30-60 minutes+ | Monitoring until the sedative effects wear off. |
| Total Visit | 1.5 - 2 hours+ | This includes all aspects from arrival to discharge. |

Key Aspects of the TOE
The transoesophageal echocardiogram is a valuable diagnostic tool, offering superior imaging quality compared to a standard echocardiogram in certain situations. It is particularly useful for:
- Evaluating heart valves in detail.
- Detecting blood clots within the heart, especially before procedures like cardioversion.
- Assessing the presence of congenital heart defects.
- Investigating sources of stroke or TIA (transient ischemic attack).
Understanding the duration and process can help alleviate any concerns you might have about undergoing this important cardiac test.
