Angioplasty

Overview

What is Coronary Angioplasty?

Coronary angioplasty, often called PCI or simply angioplasty, is a minimally invasive procedure performed by interventional cardiologists to open narrowed or blocked arteries that supply blood to the heart muscle. If coronary arteries become clogged with fatty deposits, they restrict blood flow, causing chest pain, medically known as angina and increase the risk of a heart attack.

An angioplasty procedure is not open-heart surgery. It’s performed through a small tube inserted in the wrist or groin artery. A thin catheter is navigated to the heart and to widen the artery, a tiny balloon is inflated at the site of the blockage. Most often, a small mesh tube called a stent is then placed to act as a scaffold, holding the artery open long-term. The goal is to restore normal blood flow to the heart, relieve symptoms quickly and protect the heart muscle.

Types of Coronary Artery Conditions We Treat with Angioplasty

This specialist field focuses on treating blockages caused by coronary artery disease (CAD). With the condition presenting itself in different ways, understanding urgency level is critical. Stable angina is a predictable chest pain or tightness occurring with exertion or stress which indicates a significant but stable narrowing. An angioplasty may be recommended if medication and lifestyle changes no longer control symptoms effectively.

More urgent situations are acute coronary syndromes (ACS). This includes a heart attack medically known as myocardial infarction, where a blood clot suddenly blocks an artery, which then starves part of the heart muscle of oxygen. Here, emergency angioplasty surgery, known as primary PCI, is the gold-standard treatment to open the artery as fast as possible and limit permanent heart damage. Another type is referred to as unstable angina, where chest pain occurs at rest or is worsening rapidly, signalling a blockage that is about to cause a heart attack. Angioplasty is often needed urgently to prevent the situation from worsening.

The decision to consider an angioplasty typically follows a diagnosis from a cardiologist but knowing when to seek help for potential heart artery problems is critical. The classic symptom starts with chest pain or discomfort, often described by patients as a pressure, squeezing or a heavy feeling in the centre of the chest. This pain may spread to the arms, neck, jaw, shoulder, or back. Shortness of breath, often with or without chest discomfort, is another major warning sign.

Patients should seek immediate medical attention if they experience these symptoms at rest, if they are severe or if they don't subside after a few minutes. Other signs can include nausea, light-headedness or a cold sweat. If patients have known coronary artery disease and their stable chest pain patterns change become more frequent, severe or are occurring with less activity, this also warrants an urgent review. Early assessment can determine if conditions can be managed with medication or if a procedure like an angioplasty is the best path to protect the heart.

Determining if an angioplasty procedure is right for our patients involves a careful diagnostic pathway. Evaluation of symptoms, risk factors like high blood pressure, diabetes, smoking and family history are the starting point followed by a physical exam. An electrocardiogram (ECG) is used to record the heart's electrical activity and can show signs of strain or damage. A stress test, where the heart is monitored during exercise, helps see how the heart functions under demand.

The ultimate diagnostic test is a coronary angiogram. This is a specialised X-ray procedure that is often the first step before an angioplasty. A thin catheter is threaded to the heart arteries and a special dye is injected to make them visible on X-ray. This roadmap shows the exact location, number and severity of any blockages. Based on this live imagery, an interventional cardiologist can immediately determine if a blockage is significant enough to treat and can often proceed directly to the angioplasty in the same session if it is clinically appropriate.

  • Acute Myocardial Infarction (Heart Attack)
  • Unstable Angina
  • Stable Angina
  • Blockages found after a positive stress test or abnormal scan
  • In-stent restenosis (re-narrowing of a previously placed stent)

At NMC Hospital and Clinic, our approach to angioplasty surgery is centred on precision, safety, and swift recovery. We provide lifesaving and life-enhancing treatments and procedures. The vast majority of procedures are performed via the radial artery in the wrist, which is associated with greater patient comfort, fewer complications and allows patients to sit up and walk soon afterwards. In our state-of-the-art cardiac catheterisation labs, our interventional cardiologists use advanced imaging to navigate with incredible accuracy across Abu Dhabi, Dubai, Sharjah, Ajman, Ras Al Khaimah and Al Ain.

During the angioplasty procedure, they may use specialised techniques like intravascular ultrasound (IVUS) to see inside the artery and ensure the stent is perfectly placed. We use the latest generation of drug-eluting stents, which slowly release medication to help prevent the artery from narrowing again. The procedure itself typically takes 30-90 minutes and patients are usually awake with just local anaesthesia and mild sedation. Recovery is rapid and most patients stay in hospital for only 1-2 nights for monitoring. Once they leave, they are provided with medication and cardiac rehabilitation guidance, to support long-term heart health.

Our team of consultant interventional cardiologists across Abu Dhabi, Dubai, Sharjah, Ajman, Ras Al Khaimah and Al Ain are experts in their field and come with rigorous training in complex, image-guided procedures. Performing hundreds of angioplasty procedures each year, they are skilled in handling both routine and complex, high-risk cases.

They understand that the prospect of a heart procedure can be frightening. Our consultants are compassionate with both patients and their families. Using angiogram images to clearly show the problem, they also explain precisely how they plan to fix it. They lead a dedicated team of cardiac catheterisation lab nurses and technicians. The unit is especially trained in procedures of this nature. This way, we ensure patients receive expert, calm and compassionate care from the moment they enter the lab.

Frequently Asked Questions

No, it is a minimally invasive procedure not requiring the opening of the chest. Because it’s performed through a small puncture in an artery, usually in the wrist, it has a much faster recovery than traditional bypass surgery.
Modern drug-eluting stents are designed to last patients a lifetime. A stent failing is not the main concern. What is a major concern is if new blockages develop elsewhere in the arteries or, rarely, scar tissue forms within the stent. This is why lifelong medication and healthy lifestyle changes are essential.
Generally, recovery is quick. Patients can often sit up shortly afterwards and walk within a few hours if the procedure was done through the wrist. Most people are back to light activities within a week. Driving is usually possible after a few days to a week, and many return to work within 1-2 weeks, depending on the nature of their job. Full recovery, including participation in a structured cardiac rehab programme, takes a few months.
