Who can join
Age: 18 and older. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Male or female, over 18 years of age, presenting with at least one ischemia inducing lesion in a native coronary artery that is refractory to standard guidewire crossing. Chronic total occlusion (CTO) is defined as 100% coronary blockage for over a 3-month duration documented either by prior catheterization or by clinical evaluation
- Suitable candidate for non-emergent, coronary angioplasty
- Documented de-novo or restenotic coronary chronic total occlusion defined as a lesion with TIMI 0 flow for at least 90 days refractory to conventional guidewire crossing
- Left ventricle ejection fraction > 20% within the last 12 months.
- For antegrade chronic total occlusion procedures, activated clotting time (ACT) should be > 300 sec
- Chronic total occlusion in a non-tortuous arterial segment
- Voluntarily sign a Patient Informed Consent Form specific to the study.
- Physically and mentally willing to comply with all study requirements.
You may not qualify if…
- Successful target lesion crossing with a conventional wire system prior to enrollment
- Prisoners.
- Pregnancy
- Patient has an active implantable.
- Extensive dissection created by refractory guidewire
- Severe ongoing congestive heart failure (New York Heart Association Class IV symptoms)
- Active infection
- Uncontrolled Hypertension (Systolic blood pressure > 180 mm) at the time of the procedure
- History of severe reaction to contrast media
- Recent myocardial infarction (within 2 weeks)
- In-stent target lesion
- Severe cerebrovascular disease including history of prior stroke or transient ischemic attack within 1 month at the time of the procedure
- Saphenous vein graft (SVG) chronic total occlusion or an in-stent chronic total occlusion
- Short life expectancy due to other illnesses such as cancer or pulmonary, hepatic or renal disease
- Participation in another investigational protocol at the time of the procedure
