The Department of Cardiac Sciences at Vimhans Nayati Super Speciality Hospital is one of the best heart centres in the country dedicated to delivering robust care to patients suffering from a plethora of heart-related diseases and ailments. The Department is managed by some of the renowned cardiologists offering a wide gamut of procedures including Angioplasty. Also known as percutaneous intervention or percutaneous transluminal angioplasty, it is a minimally invasive procedure used to treat narrowed or stenotic arteries so as to restore the normal flow of blood. With more than 5 lakh procedures carried in India every year, this is the preferred mode of restoring blood flow in blocked arteries. In the case of blockage, a stent is placed during the procedure to open the blocked artery.
Why is the procedure performed?
Angioplasty may be performed to address any of the following problems:
- Acute STEMI (ST-elevation myocardial infarction)
- NSTEMI (Non-ST-Elevation myocardial infarction)
- Angina, both stable and unstable
- Symptomatic stenotic arteries
- Abnormalities in the stress test
- Atherosclerotic narrowing due to peripheral artery disease
- Carotid lesions and radiation-induced stenosis
How to prepare for the procedure?
- Before initiating the procedure, it is extremely important to determine your eligibility for the same. This is done with the help of a few tests or screenings that help to evaluate the overall health of the patient.
- You may be asked to stop taking certain medications or start taking new ones. Hence it is important to inform your doctor about all the medication that you are presently taking including herbal supplements.
- The patient should not eat or drink anything starting at least 4 hours prior to the surgery. The approved medication can be taken with small sips of water.
What happens during the procedure?
Angioplasty is performed under the influence of local anaesthesia or by using sedatives. The procedure is minimally invasive and involves the use of a catheter. Before initiating the procedure, your vitals will be checked. This is done multiple times throughout the surgery.
- The surgical site is cleaned and a small incision is made to introduce the catheter, which is then guided towards the blockage site using imaging guidance.
- Doctors use a contrast dye to generate clear x-ray images.
- Once the catheter is in the right position, the balloon, present on one of its ends, is inflated to open the blocked and narrowed artery.
- In some cases, the doctors may even place a stent alongside to prevent the artery from narrowing back.
- Once the blockage has been cleared, the balloon is deflated and removed along the catheter.
- The procedure can be performed to remove multiple blockages at the same time.
What to expect after the procedure?
Post-surgery, the patients are kept under keen observation for few hours and then shifted to their room.
Patients are usually discharged within 2 to 3 days
The patient needs to go for regular check-ups to negate the risks of any complication.
