Cardiac Imaging at The London Clinic

The London Clinic is one of the few private hospitals in central London to offer a comprehensive, multi-modality cardiac imaging service. Our purpose-built stress echocardiography laboratory permits a daily, consultant-led service.

As opposed to invasive techniques, which require catheters to be inserted into the heart, non-invasive tests are safer, easier to perform, and can be used to detect various heart conditions.

These range from reduced blood flow that supplies the heart muscle (known as coronary artery disease) to abnormalities that weaken the capacity of the heart to pump blood.


Cardiac DIAGNOSTIC Tests

GPs or consultants who wish to request these tests should contact Diagnostics t: 020 7034 6330; e or via the online form.

This is indicated for patients with chest pain, breathlessness, arrhythmia and exercise-related symptoms. It is also frequently used to assess perioperative risk.

After taking a set of ultrasound images at rest, the patient then exercises on a treadmill. If this can’t be done, we can slowly infuse dobutamine, a mild form of adrenaline.

Images are then acquired immediately after exercise or during drug infusion and compared to rest pictures. Beta blockers should be withheld 48hrs prior to the test.

Total duration: 45 minutes

Transthoracic Echocardiogram is a procedure that is carried out by a sonographer who will normally apply gel to a person’s chest or to a transducer. 

They will apply pressure against the skin, where an ultrasound light will travel through your chest to the heart, from where the device will pick up sound wave echoes.

A computer is used to change the sound wave echoes into pictures on a screen. This method is conducted in order to check whether or not there are problems with a person’s heart.

An electrocardiogram (ECG) is a test used to measure the rate and regularity of your heartbeat in order to see if it is functioning properly.

Our cardiologists can perform several types of ECG to detect abnormal heartbeats.

Which ECG you have will depend on your symptoms and your individual circumstances.

This is a procedure otherwise known as an exercise stress test: where a person will be asked to walk on a treadmill or another exercise machine in order to check how the individual's heart is working whilst carrying out physical activity.

The method can show if there are any issues involving a person's blood flow inside their heart.

A heart rhythm monitor otherwise known as a holter monitor is a device that an individual wears (normally around their neck) in order to check the rhythm of the heart.

The device will pick up the person's heartbeat over the course of the days they are required to wear the device which will normally be around 2 days.   

Monitoring blood pressure is a crucial way of how to manage high blood pressure. 

By monitoring blood pressure this helps the doctor to make an early diagnosis of high or low blood pressure, and prepare you for the appropriate treatment.

Cardiac Imaging Tests and Procedures

Usually a cardiologist will advise on which test is most appropriate. These tests can all be booked through our Radiology Department (t: 0207 616 7653).

An MRI scan provides detailed images of the heart structure and function and is principally used to assess for cardiomyopathy and also coronary disease.

A dye (gadolinium) is injected to look for scarring, and a drug (adenosine) to assess blood flow.

Total duration: 60 minutes.

Indicated for patients with chest pain, using a small amount of radiation the coronary arteries can be clearly visualised.

These will show if there are any significant narrowings or if there are early signs of disease (calcification) which may require preventative cholesterol and blood pressure treatment.

Contrast dye is injected in the arm and also a drug to slow the heart rate (beta blocker) to obtain blur-free images. Therefore, this test may not be appropriate in patients with poor kidney function or severe asthma.

Total duration: 20 minutes.

3T MRI Scanner at The London Clinic

The department consists of a 1.5T MRI and a 128 slice CT scanner, situated on Floor 8 of the main hospital at 20 Devonshire Place.

We are the first hospital in the UK to offer patients advanced diagnostic scanning with the new Siemens MAGNETOM Vida 3T MRI scanner

A second 1.5T MRI scanner is located in the Outpatients centre at 5 Devonshire Place.
