Percutaneous coronary intervention (with stent)
What is a Percutaneous Coronary Intervention (with Stent)?
A Percutaneous Coronary Intervention (with Stent) is also known as a Percutaneous Transluminal Coronary Angioplasty (PTCA).
It is a procedure performed on your heart under sedation and local anaesthetic. It involves opening a narrowed or blocked segment of coronary artery by inserting a small balloon catheter via the femoral artery in the groin (or the brachial artery located in the arm).
A fine guidewire is introduced through a guide into the coronary artery. A balloon catheter is then inserted over the wire and positioned across the narrowed/blocked segment. The balloon is then inflated.
This procedure opens the narrowed artery by compressing the fatty material (plaque) against the wall of the artery and restores blood flow to the area of the heart previously deprived by the narrowed or occluded artery.
Sometimes patients can experience some angina during inflation of the balloon as the coronary artery is temporarily occluded and the heart muscle is deprived of oxygen. This only lasts for a very brief period of time and it resolves as soon as the balloon is deflated.
At the same time a stent may be placed in the coronary artery. A stent is a small mesh scaffold that supports the coronary artery and maintains patency.
How long does the procedure take?
A Percutaneous Coronary Intervention (with Stent) takes approximately 90 minutes depending on the complexity of the anatomy and its narrowing.
How long will I be at the clinic or in hospital for?
You will be admitted to the clinic where you will stay until the time of your Percutaneous Coronary Intervention (with Stent). After your procedure, you will be transferred to the Coronary Care Unit. Generally, you will stay overnight and be discharged home the following morning.
