Definition

Percutaneous coronary intervention is the most common mode of revascularization.1

Diagnosis and risk stratification

Intravascular imaging is valuable for identifying the causes of stent failure and assessing morphological characteristics.1 In-stent restenosis has an incidence of 30% at 6 months with bare-metal stents and 7% at 4 years with drug-eluting stents.2

Treatment

Antiplatelet therapy is essential to reduce the risk of thrombotic complications in patients undergoing percutaneous coronary intervention.1 Dislodged coronary stents can be retrieved using a snare or specialized device.2 Furthermore, conventional balloon pretreatment techniques aim to mitigate risk by modifying lesions prior to stent placement.3

Open questions

It remains to be seen if deep learning approaches will have a major impact on current and future practice.1 Additionally, there are current challenges in the clinical translation of nanoparticle-enhanced stents.2

How this page is built

A clinical question appears here only when its condition matches this topic, an outcome and a comparator were extracted from the studies, at least two studies and a patient count are on file, and the certainty is low or higher.

Supports benefit, no benefit shown, and mixed describe the direction of the measured effect. No benefit shown means the evidence does not support a benefit. It is not a finding of harm. Too little evidence means the question did not clear that bar.

Study count, RCT count, and patient count are separate. The patient total adds only studies that are linked into a study family and whose sample size is not flagged as implausible. A reversal is listed only when at least one randomized trial sits on each side of the change.

The overview is drafted from the guideline recommendations, trials, papers, and questions on this page, and every sentence has to cite one of them. It stays unverified until an NPI-verified clinician or a Synapse admin approves it. Approving records that person's name.
