Cardiology has advanced significantly in recent years. Today, many coronary and structural heart conditions can be treated using sophisticated, minimally invasive techniques that offer greater precision and expand the options available for complex cases.
Dr. Fady Turquieh provides advanced cardiology care in Dubai, using evidence-based technologies and interventional techniques according to each patient’s condition, coronary anatomy, symptoms, and overall cardiovascular risk.
Innovation does not mean choosing the newest treatment available. It means having access to the right technology and knowing when it can provide a meaningful clinical benefit.
Advanced Coronary Interventions
Coronary artery disease develops when plaque builds up inside the arteries that supply blood to the heart. As these arteries become narrowed or blocked, patients may experience chest pain, shortness of breath, or other symptoms. Severe blockages can also increase the risk of a heart attack.
Percutaneous coronary intervention (PCI), commonly known as coronary angioplasty, allows narrowed coronary arteries to be treated through a catheter without traditional open-heart surgery.
Modern PCI has evolved considerably. Cardiologists can now choose from different technologies according to the type, location, and complexity of the blockage.
Drug-Eluting Stents
A coronary stent is a small mesh-like tube placed inside an artery to help keep it open after angioplasty.
Modern drug-eluting stents (DES) are coated with medication that is gradually released into the artery wall. This medication helps limit excessive tissue growth and reduces the risk of the treated area becoming narrowed again, known as restenosis.
The type and size of stent, as well as the strategy used to place it, depend on the patient’s coronary anatomy and the characteristics of the blockage.
Drug-Coated Balloons
A drug-coated balloon (DCB) is an angioplasty balloon coated with medication. When the balloon is temporarily inflated inside the narrowed artery, the medication is transferred to the vessel wall.
Unlike a stent, the balloon is then removed and does not leave a permanent implant behind.
Drug-coated balloons can be particularly useful in selected coronary situations, including some cases of restenosis within a previously implanted stent and certain small-vessel lesions. However, they are not a replacement for stents in every patient.
Choosing between a drug-coated balloon, a drug-eluting stent, or another treatment strategy requires careful assessment of the individual coronary lesion.
Intravascular Lithotripsy for Calcified Coronary Arteries
Calcium deposits can make coronary artery disease considerably more difficult to treat.
When an artery becomes heavily calcified, it may resist conventional balloon expansion. This can make it difficult to adequately prepare the artery or fully expand a coronary stent.
Intravascular lithotripsy (IVL) offers another approach for selected patients with heavily calcified coronary lesions.
How Does Intravascular Lithotripsy Work?
IVL uses a specialized catheter that delivers acoustic pressure waves within the coronary artery.
These waves modify calcium within the vessel wall while minimizing injury to surrounding soft tissue. Once the calcium has been disrupted, the artery can become more compliant and easier to expand with a balloon.
If a stent is required, preparing a heavily calcified artery appropriately can help achieve better stent expansion.
Intravascular lithotripsy has therefore become an important tool for treating selected complex calcified coronary lesions.
Intravascular Imaging: Seeing the Artery From Within
Traditional coronary angiography provides essential information about the coronary arteries. However, certain complex procedures can benefit from an even more detailed view.
Intravascular imaging technologies allow cardiologists to examine the artery from inside the blood vessel.
Intravascular Ultrasound (IVUS)
IVUS uses ultrasound from within the coronary artery to provide detailed cross-sectional images of the vessel.
It can help assess:
- The size of the artery
- The extent and distribution of plaque
- Characteristics of certain coronary lesions
- Appropriate stent sizing
- Stent expansion and positioning
This additional information can help guide and optimize selected coronary interventions.
Optical Coherence Tomography (OCT)
OCT is another intravascular imaging technology. It uses near-infrared light to produce very high-resolution images of the inside of a coronary artery.
Depending on the clinical situation, OCT can help cardiologists examine plaque and vessel characteristics, assess a previously implanted stent, and optimize PCI.
IVUS and OCT do not replace clinical judgment or coronary angiography. Instead, they provide additional information when greater precision is needed.
Complex Coronary Interventions
Not all coronary artery disease is straightforward.
Some patients have long or heavily calcified lesions, multiple affected arteries, bifurcation lesions where an artery divides into two branches, chronic total occlusions, or disease involving previously implanted stents.
These cases may require a more sophisticated interventional strategy and specialized technologies.
Modern complex PCI may combine several approaches, including:
- Advanced guidewire and catheter techniques
- Drug-eluting stents
- Drug-coated balloons
- Intravascular lithotripsy
- IVUS or OCT guidance
- Specialized techniques for complex coronary anatomy
The treatment strategy should always be selected according to the patient’s anatomy, clinical condition, and expected benefits and risks.
Advanced Treatment for Heart Valve Disease
Innovation in cardiology extends beyond coronary artery disease.
Some patients with severe heart valve disease may now be candidates for catheter-based treatment rather than conventional open-heart surgery.
Transcatheter Aortic Valve Implantation (TAVI/TAVR)
TAVI, also known as TAVR, allows a replacement aortic valve to be delivered through a catheter. It is an established treatment option for selected patients with severe aortic stenosis.
Whether a patient is suitable for TAVI or surgical valve replacement depends on several factors. These include age, anatomy, symptoms, other medical conditions, procedural risk, and the recommendations of the multidisciplinary heart team.
Other transcatheter technologies are also increasingly used to manage selected forms of structural and valvular heart disease.
Advanced Treatment for Heart Rhythm Disorders
Advances in electrophysiology have also expanded treatment options for patients with cardiac arrhythmias.
Depending on the type of rhythm disorder, treatment may include medication, electrical cardioversion, implanted cardiac devices, or catheter-based procedures.
Catheter Ablation
During catheter ablation, specialized catheters are guided into the heart to identify the tissue responsible for certain abnormal electrical signals.
Energy is then delivered to modify or eliminate the small area responsible for the arrhythmia.
Ablation can be an effective treatment for selected patients with conditions such as supraventricular tachycardia, atrial flutter, atrial fibrillation, and some other rhythm disorders.
Choosing the Right Innovative Treatment
Advanced technology has created more cardiovascular treatment options, but not every patient needs an advanced procedure.
The right treatment depends on factors such as:
- The specific cardiovascular condition
- Severity of the disease
- Coronary or structural anatomy
- Symptoms
- Previous treatments or procedures
- Other medical conditions
- Overall cardiovascular and procedural risk
For some patients, medication and lifestyle management remain the most appropriate approach. Others may benefit from conventional PCI, while more complex cases may require specialized devices or techniques.
The purpose of an advanced cardiac evaluation is therefore not to choose the most innovative treatment. It is to determine which treatment offers the most appropriate balance of benefit and risk for that individual patient.
