When your coronary arteries are blocked or narrowed, your blood circulation is reduced. This results in a number of symptoms including muscle pain, tissue damage, and dizziness since the affected areas in your body are deprived of necessary oxygen and blood.
To combat these symptoms, angioplasty, also known as stenting, can be performed for treating your blocked or narrowed arteries. The angioplasty procedure utilises either a balloon for stretching an artery, or a stent, which is a metal scaffold, for holding your artery open. These procedures will be able to improve your heart’s blood circulation, effectively alleviating your symptoms. Be Heart Strong shares more information below:
What is a Typical Coronary Angioplasty Procedure Like?
To begin, local anaesthesia will be applied to numb your skin. A tiny tube will then be inserted into your groin artery. If your groin artery is deemed unusable, an artery in your wrist may be used instead. Several X-ray images of your arteries will then be taken with aid from a special dye that, when injected, will show all blocked areas in the images. Note that it is perfectly normal to feel warm every time the dye is injected.
A tube and fine wire will then be inserted through your blocked arteries with help from the X-ray. The balloon is inserted next alongside the wire and across the blockages or narrowing areas and inflated gently and slowly to allow your blood to circulate easily. Afterwards, the balloon is deflated and removed from your artery. Your doctor may need to insert more dye and take more X-ray images to check if the angioplasty procedure is a success or a failure. The whole procedure is typically 30 to 45 minutes long, but can last for as long as two hours in some cases.
Angioplasty Success Rates
Angioplasty is successful in roughly 90% to 95% of patients. On the other hand, if the procedure fails to improve your blood circulation, stenting may be considered. When the stent has been put in place, it will stay in place and will be covered by your artery’s lining over time. For the 5% to 10% of patients whose angioplasty and stenting procedures failed, surgical bypass operation may be recommended.
