See clearly. Treat optimally.

Philips coronary solutions give you the visualization needed to quickly and precisely assess complex PCI challenges so you can treat optimally with Philips therapeutic solutions.

Complex PCI cases are becoming more common, leading to an increased risk of adverse events.¹

Clear procedural guidance and optimal vessel preparation can help you achieve better outcomes. Explore the different challenges seen in complex PCI cases and how Philips’ specialty tools can help you.

In-stent restenosis (ISR)

Real-world incidence rates of in-stent restenosis (ISR) account for 12% of PCI.²Each patient requires a customized treatment strategy based on the extent and mechanism of their restenosis, requiring flexibility in your toolkit and approach.^3,4

Rates of restenosis at follow up²

Clinical challenges

Target lesion revascularization rates remain an issue even today when using multiple overlapping stents.

– 2^ndstent 12-16% at 12 months and 33% at 3-5 years⁵

– 3^rd stent 25% at 6 months⁵

Angiography alone cannot provide the information necessary to fully understand the mechanism and extent of ISR.³

– Difficult to identify under-expansion or mal-apposition

– Challenging to determine if it is geographical miss or under-sizing

– Inability to discern between neointimal hyperplasia or neo-atherosclerosis

Traditional mechanical tools have limitations for treating ISR.

– Mechanical tools, from angioplasty to rotational or orbital atherectomy, are largely ineffective in restenotic lesions.⁶

– The unique soft, aqueous morphology of neointimal hyperplasia tissue presents a challenge to mechanical intervention.⁶

Ostial and bifurcation lesions

Ostial and bifurcation lesions represent nearly 40% of complex PCI’s.⁹

Philips image on file

Clinical challenges

Chronic total occulsions (CTOs)

Incidence increases with age, yet older patients are less likely to have PCI attempted.¹⁴ Furthermore, 18% of PCIs have a CTO, but less than 5% are being treated.¹⁵

CTO of the RCA - image provided by Craig Thompson, MD

Clinical challenges

CTOs are difficult to wire and re-canalize, resulting in lengthy procedures and potentially higher radiation exposure and contrast use.
CTOs are often associated with lower procedural success rates, increased restenosis and re-occlusion compared with non-CTO procedures.^16,17
Hard proximal caps often prevent therapy from being delivered.

Philips is here to help you achieve better outcomes in CTO cases

Calcified lesions

An increasing number of patients with calcified coronary artery lesions are being referred for PCI. A recent pooled analysis reported moderate to severe target lesion calcification in 32% of patients.²¹

Digital grayscale EEP plaque with calcium

Philips image on file

Clinical challenges

Angiographic measures of procedural success, such as acute gain and diameter stenosis, are often worse in calcified lesions.^22,23,24
Stent under-expansion, asymmetric expansion, and mal-apposition are frequently observed in heavily calcified lesions.^25,26,27
Noncompliant calcified plaques often require high-pressure balloon dilation, increasing the risk for adverse events such as coronary dissection and thrombosis.^28,22,23

Diffuse disease

Approximately 20% of the coronary lesions treated today are greater than 20mm in length.^32,33

Image courtesy of Alphonse Ambrosia, DO

Clinical challenges

Diffuse or long lesions are associated with decreased procedural success and are associated with higher rates of restenosis.³⁴

– Stent length is an independent predictor of in-stent restenosis and thrombosis³⁵

– Stenting long segments with multiple and or overlapping stents may lead to injury to the vessel wall integrity³⁶

Angiography alone may not be able to identify the critical lesion.

– Diffuse CAD may be underestimated by evaluation with coronary angiography³⁷

– Determining reference vessel sizing can be challenging when the vessel is diffusely diseased³⁸

Philips is here to help you achieve better outcomes in diffuse disease cases

ELCA important safety information
Indications: The laser catheters are intended for use either as a stand-alone modality or in conjunction with percutaneous transluminal coronary balloon angioplasty (PTCA) in patients who are acceptable candidates for coronary artery bypass graft (CABG) surgery. The following indications for use, contraindications and warnings have been established through multicenter clinical trials. The Philips CVX-300 Excimer laser system and the multi-fiber laser catheter models are safe and effective for the following indications: occluded saphenous vein bypass grafts, ostial lesions, long lesions (greater than 20mm in length), moderately calcified stenosis, total occlusions traversable by a guidewire, lesions which previously failed balloon angioplasty, restenosis in 316L stainless steel stents, prior to the administration of intravascular brachytherapy. These lesions must be traversable by a guidewire and composed of atherosclerotic plaque and/or calcified material. The lesions should be well defined by angiography.
Contraindications: Lesion is in an unprotected left main artery. Lesion is beyond acute bends or is in a location within the coronary anatomy where the catheter cannot traverse. Guidewire cannot be passed through the lesion. Lesion is located within a bifurcation. Patient is not an acceptable candidate for bypass graft surgery.
Potential adverse events: Use of the Philips CVX-300 Excimer laser system may contribute to the following complications: dissection of the arterial wall, perforation, acute reclosure, embolization, aneurysm formation, spasm, coronary artery bypass graft surgery, thrombus, myocardial infarction, arrhythmia, filling defects, death. No long term adverse effects of ELCA are known at this time.
Risks: The primary endpoint defined in the laser angioplasty of restenosis stents (LARS) randomized trial was the absence of major adverse cardiac events (MACE) at 6 months: Death; myocardial infarction; coronary artery bypass surgery. Procedural complications include: any dissection, acute thrombus, haziness, no reflow, arrhythmia, acute vessel closure, occlusion of side branch, occlusion non-target, coronary spasm, coronary embolism, coronary perforation, laser/stent damage, balloon/stent damage, and other serious.

AngioSculpt PTCA important safety information
The AngioSculpt scoring balloon catheter is indicated for use in the treatment of hemodynamically significant coronary artery stenosis, including in-stent restenosis and complex type C lesions, for the purpose of improving myocardial perfusion.
The AngioSculpt catheter should not be used for coronary artery lesions unsuitable for treatment by percutaneous revascularization, and coronary artery spasm in the absence of a significant stenosis.
Possible adverse effects include, but are not limited to: death; heart attack (acute myocardial infarction); total occlusion of the treated artery; coronary artery dissection, perforation, rupture, or injury; pericardial tamponade; no/slow reflow of treated vessel; emergency coronary artery bypass (CABG); emergency percutaneous coronary intervention; CVA/stroke; pseudoaneurysm; restenosis of the dilated vessel; unstable chest pain (angina); thromboembolism or retained device components; irregular heart rhythm (arrhythmias, including life-threatening ventricular arrhythmias); severe low (hypotension)/high (hypertension) blood pressure; coronary artery spasm; hemorrhage or hematoma; need for blood transfusion; surgical repair or vascular access site; creation of a pathway for blood flow between the artery and the vein in the groin (arteriovenous fistula); drug reactions, allergic reactions to x-ray dye (contrast medium); and infection.
