Stenting (Coronary, Renal)

Catheter-based stent placement to restore arterial blood flow.

Stenting is the catheter-based placement of a small, expandable metal scaffold inside a narrowed or blocked artery to restore blood flow. Coronary stenting (a key component of percutaneous coronary intervention, or PCI) is the most common application, performed after balloon angioplasty to keep the artery open and prevent re-narrowing. Renal artery stenting is reserved for select patients with hemodynamically significant renal artery stenosis causing resistant hypertension or recurrent flash pulmonary edema. Other arterial beds (carotid, peripheral, iliac) have specific stenting indications managed by vascular specialists. Dr. Kedan evaluates whether stenting is the right next step for your situation and coordinates the procedure through Cedars-Sinai.

What This Treatment Approach Includes

  • Non-invasive evaluation first — stress testing, coronary CT angiography, or vascular imaging
  • Symptom and physiologic assessment to confirm stenting will provide meaningful benefit
  • Pre-procedure planning: anticoagulation, kidney function optimization, antibiotic prophylaxis
  • Coordination with Cedars-Sinai interventional cardiology
  • Selection of drug-eluting stent type and access site
  • Post-procedure dual antiplatelet therapy plan
  • Secondary prevention regimen — statin, blood pressure control, cardiac rehab

How It Works

A catheter is advanced through the radial or femoral artery to the target lesion under X-ray guidance. A balloon is inflated across the narrowing to compress the plaque, then a drug-eluting stent is deployed in its expanded position. Modern drug-eluting stents release medication over time that prevents tissue regrowth inside the stent, dramatically reducing restenosis rates compared with bare-metal stents or balloon angioplasty alone. The stent becomes incorporated into the arterial wall over weeks to months.

Who This Is For

  • Acute heart attack — emergency coronary stenting for ST-elevation myocardial infarction
  • Acute coronary syndrome based on risk-stratified approach
  • Stable coronary disease with symptoms despite optimized medical therapy
  • High-risk coronary anatomy (left main, proximal LAD, multi-vessel disease in selected patients)
  • Restenosis or progression after prior intervention
  • Renal artery stenosis causing resistant hypertension or recurrent pulmonary edema (selected patients)
  • Carotid or peripheral arterial disease with specific clinical indications (vascular team)

Monitoring and Follow-Up

Dual antiplatelet therapy duration is set at the time of stenting based on indication, stent type, and bleeding risk — typically several months to a year for coronary stents. Follow-up emphasizes blood pressure and lipid optimization, repeat testing only if symptoms recur, and cardiac rehabilitation enrollment. Dr. Kedan provides the longitudinal care, with same-day access for new chest pain or concerning symptoms in the post-procedure window and beyond.

How Cardiolucent Manages This

The benefit of coronary stenting for stable disease is real but conditional — for many patients, optimized medical therapy achieves comparable outcomes without procedural risk. Dr. Kedan reviews the evidence with you in extended visits before referral, coordinates timing with Cedars-Sinai, and remains the continuity cardiologist before, during, and after. POCUS, same-day labs, and direct access support tight post-procedure care, especially through the high-stakes dual antiplatelet window.

Common Questions

Frequently Asked Questions

What is a stent?
A stent is a small, expandable metal mesh tube placed inside a narrowed artery to keep it open. Modern coronary stents are drug-eluting — coated with medication that prevents tissue regrowth inside the stent. Stents become incorporated into the arterial wall over weeks to months as the inner lining heals over them.
Who needs coronary stenting?
Coronary stenting is standard of care for acute ST-elevation heart attack and is used in higher-risk acute coronary syndromes. For stable coronary disease, stenting is appropriate when symptoms persist despite optimized medical therapy or when anatomy poses elevated risk. Many patients with stable disease do equally well on aggressive medical therapy without a stent.
What is the difference between a drug-eluting stent and a bare-metal stent?
Drug-eluting stents release medication over time that prevents tissue regrowth inside the stent, sharply reducing restenosis rates. Bare-metal stents do not have this coating and are used much less commonly today. Modern drug-eluting stents have excellent long-term patency and are preferred for nearly all indications.
What about renal artery stenting?
Renal artery stenting is appropriate in select patients with hemodynamically significant renal artery stenosis causing resistant hypertension, recurrent flash pulmonary edema, or progressive renal failure. The procedure has narrow indications because trials have shown limited benefit in unselected patients — careful candidate selection is essential.
What medications will I need after a stent?
Dual antiplatelet therapy (aspirin plus a P2Y12 inhibitor — clopidogrel, ticagrelor, or prasugrel) is required for a defined period that depends on stent type, indication, and bleeding risk. High-intensity statin therapy continues indefinitely, along with blood pressure optimization and other secondary-prevention medications.
How long is recovery after stenting?
Most patients are discharged the same day or the morning after and resume light activity within a few days, with restrictions on heavy lifting for about a week. Cardiac rehabilitation is encouraged within several weeks and significantly improves outcomes.
What are the main risks?
Coronary stenting is generally safe but carries small risks of bleeding at the access site, kidney injury from contrast dye, arrhythmia, coronary dissection or perforation, stent thrombosis, heart attack, stroke, and rarely emergency bypass surgery. Risks are individualized and depend on anatomy, kidney function, and overall health.
Can I stop antiplatelet therapy if I feel fine?
No — premature discontinuation of antiplatelet therapy after stent placement sharply increases the risk of stent thrombosis, which is often catastrophic. Any change requires coordinated planning with Dr. Kedan, especially within the defined dual antiplatelet window.
Will I need another stent later?
Modern drug-eluting stents have excellent long-term patency, but coronary disease is a systemic process — new lesions can develop in other locations over years. Aggressive secondary prevention is what protects you from future events. Repeat catheterization is performed only when symptoms recur, not routinely.
How do I start a stenting evaluation with Dr. Kedan?
Schedule a consultation at the Beverly Hills office with prior stress tests, imaging, and EKGs. Cardiolucent is a concierge practice and does not bill Medicare or insurance, though a detailed superbill is provided for out-of-network reimbursement. The procedure itself is performed at Cedars-Sinai. Call (310) 304-5555 or use the contact form.
