Vis-Rx Prime Micro-Imaging Catheter Study

This is a single arm, unblinded, multi-center, clinical evaluation that will be performed at 3 to 5 investigational sites in the United States with subjects who undergo HF-OCT imaging as part of their cardiac catheterization procedure. This study will evaluate a range of device operators (interventional cardiologists) as well as patients and vessels consistent with the product labeling. The operator evaluation will be determined post use of the device using a Likert Grading Scale. Clear Image Length of the acquired HF-OCT image will be measured by an independent core lab. Safety will be monitored through the interventional procedure and Adverse Events that are potentially related to either the device or the procedure will be recorded, evaluated and analyzed.

Inclusion criteria

• Patients 18 years of age or older
• Patients willing and able to provide written informed consent to participate in evaluation

• Acute renal failure
• Disqualified for Coronary Artery Bypass Graft surgery
• Disqualified for Percutaneous Coronary Intervention
• Patients currently enrolled in another study to evaluate an investigational device or medication
• Any target vessel which has undergone a bypass procedure

The lesion-specific exclusion criteria assessed from angiography are:

• Total occlusion
• Coronary artery spasm
• Large thrombus (as visible under angiography)
