Interventional Cardiology
Coronary Angioplasty & Stent Placement (PCI)
Coronary angioplasty opens a blocked heart artery using a tiny balloon and often a stent. The procedure is done through a small wrist puncture, takes about an hour, and lets most patients return home the same day.
AVERAGE PROCEDURE TIME
45 to 90 minutes
Anesthesia
Light sedation, local
Recovery
Same day, 4 to 6 hours
Ride home
Required if you receive sedation
Overview
Angioplasty reopens a coronary artery narrowed by plaque. A balloon is inflated at the blockage and, in most cases, a drug-eluting stent is placed to hold the artery open permanently.
The work is done through a wrist puncture using imaging and pressure measurements to confirm that the blockage is significant and that the result is complete.
Is this right for me?
Candidacy is confirmed after a review of your history, imaging, and medications. Patients we most often treat include those with:
- A significant blockage confirmed on catheterization or CT
- Angina that limits daily activity despite medication
- Stable coronary disease appropriate for outpatient treatment
- Medically stable with a caregiver available for 24 hours
What to expect, step by step
Arrival and preparation
You check in with a coordinator, change into a gown, and meet your nurse. Vitals are taken, an IV is started if needed, and your care team reviews the plan and answers questions with your caregiver present.
Crossing the blockage
A hair-thin wire is passed across the narrowing under X-ray guidance. Imaging or pressure wires confirm the lesion needs treatment.
Balloon and stent
A balloon is inflated for a few seconds to open the vessel, then a drug-eluting stent is deployed and expanded against the artery wall.
Confirming flow
Final images document restored blood flow. Antiplatelet medication is started or adjusted before discharge.
Recovery suite
You rest in a private recovery bay while your nurse monitors vitals and comfort. Written instructions are reviewed with you and your caregiver before discharge.
Home the same day
A caregiver drives you home. A member of our team calls the next business day to check on you and confirm your follow-up appointment.
Recovery
You are observed for several hours with continuous monitoring. Most patients go home the same evening.
Take antiplatelet medication exactly as prescribed. Light activity resumes the next day, full activity within a week.
Risks and what we watch for
Every procedure carries risk. These are the ones we discuss most often for this procedure.
- Bleeding, bruising, or soreness at the access site or incision
- Infection, which is why sterile technique and, when indicated, antibiotics are used
- Reaction to sedation, anesthesia, or contrast dye, monitored continuously by your anesthesia provider
- Incomplete relief of symptoms, or symptoms that return over time
- The need for additional treatment, imaging, or a different procedure
- Rarely, a complication serious enough to require a higher level of care than an outpatient setting provides
We review these with you in detail before you consent, and you can change your mind at any point.
Coverage note
We verify your benefits and give you a written estimate before scheduling.

Frequently asked questions
How long does a stent last?
Modern drug-eluting stents are permanent. Keeping the artery open depends on taking your antiplatelet medication and managing cholesterol and blood pressure.
Can I feel the stent?
No. The stent is smaller than a spring in a ballpoint pen and becomes lined by your own artery tissue within weeks.
Is coronary angioplasty and stenting done as an outpatient procedure?
Yes. It is performed at our ACHC-accredited ambulatory surgery center in The Woodlands, minutes from Tomball and Spring, and patients go home the same day with a caregiver.
Will my insurance cover it?
Coverage depends on your specific plan and benefits. Our team verifies your benefits and gives you a written estimate before anything is scheduled.
Do you offer Spanish-speaking support?
Yes. Bilingual English and Spanish coordination is available from your first call through recovery instructions and follow-up.
