Cardiac Procedures & What to Expect
Modern cardiology is increasingly done through small punctures rather than large incisions. This guide walks through the most common catheter-based and minimally invasive procedures — what they treat, how they're done, and what recovery looks like.

Why procedures are used
Procedures answer two questions medication cannot. First, they can definitively map the anatomy — showing exactly where and how much a vessel is narrowed. Second, they can restore blood flow or treat a source of pain in a single session, often with same-day discharge.
The bar for offering a procedure is high: symptoms, imaging, and shared decision-making all have to line up. Not every narrowing needs a stent.
Cardiac catheterization and stenting
During a cardiac catheterization, a thin tube is guided from the wrist or groin to the heart's arteries. Contrast dye and X-ray reveal blockages in real time. If a critical narrowing is causing symptoms, a stent — a small mesh scaffold — can be placed to hold the artery open, often in the same procedure.
Most patients are awake but comfortable. Recovery is typically hours, not days.
Vascular procedures for the legs
The same catheter techniques treat blocked leg arteries in patients with PAD. Angioplasty (a small balloon), atherectomy (shaving plaque), and stenting can restore flow, relieve claudication, and help wounds heal.
Venous procedures — including radiofrequency ablation and sclerotherapy — treat varicose veins and venous insufficiency in an office setting.
Genicular artery embolization for knee pain
GAE is a newer, minimally invasive option for chronic knee osteoarthritis pain that has not responded to conservative care. Tiny particles are delivered through a catheter to abnormal blood vessels around the knee, reducing inflammation and pain — often without joint replacement.
It is not right for every patient, but for well-selected candidates it can dramatically improve quality of life with minimal downtime.
Recovery, safety, and follow-up
Most catheter procedures involve a small puncture site rather than a surgical incision, which means low pain scores, short recovery, and quick return to daily activities. Serious complications are uncommon in well-selected patients.
Follow-up matters. Medications after stenting or intervention protect the result, and a structured plan for risk-factor control is what makes the benefit last.

When to see a cardiologist
You don't have to wait for a procedure to be recommended by someone else. If any of the following apply, a second opinion is reasonable.
- Chest pain, pressure, or tightness — especially with exertion or shortness of breath.
- Palpitations, fainting spells, or a heart rhythm that feels irregular.
- Leg pain when walking, non-healing wounds, or new leg swelling.
- Family history of early heart disease, or personal history of high blood pressure, diabetes, or high cholesterol.
- You want a proactive, preventive evaluation and a personalized plan.
