How does it work?

Optical coherence tomography works by inserting a special type of OCT catheter that emits a near infra-red light once it reaches the coronary arteries. An imaging probe collects the data produced from the light reflecting back, and converts this into high resolution images taken from inside the coronary arteries. These images are then displayed in real time which enables your doctor to assess the extent of any plaque build-up, evaluate the health of the artery walls, observe any abnormalities and make an informed treatment decision. 

Why is it performed?

Your doctor may recommend a transoesophageal echocardiogram if they need more detailed information about your heart. It is used to evaluate symptoms of various heart conditions that typically include:

• Atherosclerosis – a build-up of plaque in the coronary arteries
• Cardiomyopathy – enlargement of the heart
• Heart failure
• Heart valve disease
• Heart infection
• Stroke

Procedure

A transoesophageal echocardiogram usually takes under one hour.

• A local anaesthetic is used to numb the back of your throat before the procedure begins 
• The probe is guided through your mouth and down your throat
• Once in place, the images are taken and evaluated
• The probe is removed

Recovery

After the transoesophageal echocardiogram has finished you will be transferred to a recovery area and monitored until you are discharged by your treating doctor. Your throat may feel sore after the procedure, but you are likely to be able to resume daily activities as soon as the anaesthetic has worn off, and your gag reflex has returned.
