Intravascular ultrasound use for stent optimization during percutaneous coronary intervention in a toddler with post-surgical stenosis after coronary reimplantation for ALCAPA

Intravascular Ultrasound Guided Percutaneous Coronary Intervention for Chronic Total Occlusion

Chronic total occlusion (CTO), a fascinating and dynamic niche in the realm of coronary artery disease, represents a major technical challenge for interventional cardiologists despite evolution of better guidewires, devices, experience and techniques. Effective wiring technique is the corner stone to success of percutaneous coronary intervention (PCI) in CTO. As a guide for guidewire crossing i...

In stent restenosis after percutaneous coronary intervention

New stent design for use in small coronary arteries during percutaneous coronary intervention

Patients with diabetes mellitus, of female gender, increased age, and/or with peripheral vascular disease often develop coronary stenoses in small caliber vessels. This review describes treatment of these lesions with the paclitaxel-eluting 2.25 mm TAXUS(®) Liberté(®) Atom™ stent. Given the same stent composition, polymer, antirestenotic drug (paclitaxel), and release kinetics as the first-gene...

Myocardial Injury after Percutaneous Coronary Intervention for In-Stent Restenosis Versus de novo Stenosis.

OBJECTIVE Periprocedural myocardial injury (PMI) remains a relatively common complication even after successful procedures. In-stent restenosis (ISR) may be involved in lesion-related factors for PMI. We compared the incidence of PMI between patients with ISR and those with de novo stenosis. METHODS The study population consisted of 121 patients with coronary artery disease who had been treat...

Reconstruction of an accidentally crushed stent guided by intravascular ultrasound during a left main percutaneous coronary intervention.

We present a case of an accidentally crushed stent due to an unnoticed passage of a guidewire through a lateral stent strut with subsequent stent compression after balloon dilatation, during a planned percutaneous coronary intervention on the left main. The crushed stent segment was reconstructed with step-by-step balloon dilation, guided by intravascular ultrasound.
