Cardiology and Interventional Cardiology

Mediclinic City Hospital’s Cardiology department is equipped to deal with a wide range of heart conditions, using both preventative and therapeutic treatment modalities.

The following investigations are regularly undertaken:

Diagnostic tests

Electrocardiogram (ECG) - recording of the electrical waves from the heart to assess the heart rate, rhythm, heart wall thickness and chamber enlargement as well as early detection of heart attacks.

Chest x-ray

To assess heart size and to look for early signs of heart failure.

Holter monitoring

A small walkman size device connected to the chest wall with wires, which records the ECG for 24 hours. This will be analysed by a special computer. The final report shows us the 24 hour pattern of the heart rhythm at work and at rest. The readings are evaluated by our senior consultants.

Ambulatory blood pressure monitoring

A special blood pressure cuff is connected to the patient's arm which records the blood pressure and pulse rate on a cassette recorder.

Treadmill exercise test

The patient walks on a computerised treadmill at a predetermined speed and gradient. The blood pressure, heart rate and ECG are continuously monitored by the computer during the exercise. This is a sensitive test to detect early signs of heart disease, specially heart attacks or blockage in the coronary arteries. This test is always conducted in the presence of a cardiologist.

Echo doppler test with colour doppler blood flow imaging

Using ultrasound the heart is imaged from various angles. Heart chambers, muscles, valves and blood vessels can all be seen on the video screen and measurements made. Colour blood flow imaging is used to detect all normal and abnormal blood flow patterns inside heart chambers and blood vessels and to measure the velocity of blood flow for precise diagnosis of abnormalities.

Intensive cardiac care unit (ICCU)

We have a state-of-the art intensive care unit with facilities for bed side and central monitoring of ECG, blood oxygen, bllood pressure or venous pressure. The unit is staffed by some of the best trained nursing staff and fully trained doctor and is fully equipped for artificial ventilation of patients with respiratory or cardiac failure. We also have facilities for temporary transvenous cardiac pacing and Swan-Ganz catherisation.

Inpatient Rooms

Private ward rooms also include facilities for bedside monitoring of ECG and blood oxygen saturation.

Preventative cardiology

Risk factor profiling is undertaken for all patients attending the department. Early detection and treatment of risk factors for heart attacks is the only method of reducing the incidence of death and disability due to heart attacks in the community. Our lipid profile examining facility estimates directly all sub fractions of cholesterol and ApoA1 and ApoB, the carrier proteins for cholesterol. Similarly the serum homocysteine, one of the early correctable risk factors for heart attack and stroke, can be detected.

Heart Valves: Operations and Procedures

The aortic valve is one of four valves that regulate blood flow in the correct direction through the heart.

The aortic valve separates the heart's main pumping chamber (left ventricle) and the main artery that supplies oxygen-rich blood to your body (aorta).

With each contraction of the ventricle, the aortic valve opens and allows blood to flow from the left ventricle into the aorta. When the ventricle relaxes, the aortic valve closes to prevent blood from flowing backwards into the ventricle.

When the aortic valve is not functionaing properly, it can interfere with blood flow as well as force the heart to work harder to supply the necessary blood to the rest of your body.

In some people, aortic valve disease may not cause any signs or symptoms for many years, if at all. In other symptoms may include shortness of breath, fatigue, chest pain, loss of consciousness, irregular heartbeat (arrhythmia), heart failure and sudden cardiac death.

Aortic valve repair or aortic valve replacement can treat aortic valve disease and help restore normal blood flow, reduce symptoms, prolong life and help preserve the function of your heart muscle.

TRAnscatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI).

This minimally invasive surgical procedure repairs the valve without removing the old, damaged valve. Instead, it wedges a replacement valve into the aortic valve's place.

Minimally invasive heart surgery may involve a shorter hospital stay, quicker recovery and less pain than traditional open-heart surgery. Minimally invasive heart surgery should generally be performed by a multidisciplinary heart team experienced in these types of procedures.

During TAVI, highly specialised Interventional cardiologists may access your heart through a blood vessel in your leg or a small incision in the chest. A hollow tube (catheter) is guided through your veins to the aortic valve. Once it is positioned correctly, a balloon-expandable or self-expandable replacement aortic valve is inserted.

TAVR may be an option for people who are considered to be at intermediate or high risk of complications from surgical aortic valve replacement.

TAVR may also be an option if you have an existing biological tissue valve that was previously inserted to replace the aortic valve, but is not working well anymore.

The CoreValve™ Evolut™ PRO is the newest transcatheter aortic valve replacement (TAVR) system by global medical technology developer Medtronic. The self-expanding device is intended to treat patients with severe aortic stenosis who are considered at high or extreme risk for open-heart surgery.

Mediclinic City Hospital performed the first CoreValve™ Evolut™ PRO procedure in the Middle East, Africa, Central Asia and Turkey (MEACAT), making the UAE the pioneer of yet  another technological breakthrough in the field of medicine in the region.

The procedure was performed by leading consultant interventional cardiologist Dr. Talib Majwal at the hospital in Dubai Healthcare City. Dr. Majwal successfully completed the percutaneous coronary interventional procedure by inserting an advanced transcatheter aortic valve replacement using femoral access.

The Evolut™ PRO System offers unique value design and advanced sealing technology to enhance valve sealing performance and in turn addresses the occurrence of blood leaking through the sides of the valve. Preventing leakage in turn leads to preserving patients’ heart muscles for an elongated period of time.

The Evolut™ PRO technology is proven to allow for faster recovery of patients as well as cause fewer complications compared to other technologies.
