NCT03237169

Brief Summary

To test the feasibility and diagnostic accuracy of a new automated pressure derived resting index (Pd/Pamin), using FFR as gold standard, in de novo coronary lesions in which invasive physiological evaluation is warranted.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Diagnostic accuracy of Pd/Pamin vs FFR

    Agreement will be tested using the established FFR 0.8 threshold as the binary reference standard.

    baseline

Secondary Outcomes (2)

  • Discriminative power of Pd/Pamin and the best cut-off, taking FFR as gold

    baseline

  • Feasibility of Pd/Pamin measurements

    Baseline

Study Arms (1)

Prospective cohort

Prospective cohort of patients with stable or stabilized coronary artery disease and de novo coronary lesions, in whom functional evaluation is performed, according do standard clinical indications.

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Consecutive subjects scheduled for coronary angiography or PCI in whom operator decides to perform FFR will be approached for enrollment. Being a first-in-man study of a novel pressure index intended for future validation and use in a clinical setting, a full assessment of its range throughout the entire spectrum of lesion severity is warranted. As such, the protocol will allow for the inclusion of both less severe as well as of critical (\>90%) lesions. Patients with either single or multiple vessel disease will be included. Data on additional lesions may or may not be collected but will not be used in the study. Vessels with sequential stenosis and tandem lesions will be evaluated and treated according to routine clinical practice, but not included in the study data collected.

You may qualify if:

  • Patients undergoing FFR assessment for standard clinical indications, according to individual operator decision.
  • Age ≥ 18 years.
  • Provided signed written informed consent for data collection the collection.
  • De novo coronary artery disease in target vessel.
  • Single or multiple vessel disease.
  • Patient eligible for elective or ad hoc PCI (or CABG), if revascularization is deemed indicated, in the setting of stable coronary artery disease or non-culprit lesions of non-ST elevation acute coronary syndromes (only in deferred procedures).
  • Stenosis deemed amenable for both evaluation with a pressure wire and for potential revascularization.

You may not qualify if:

  • Subjects with restenosis in the target vessel.
  • Known severe renal insufficiency (examples being but not limited to eGFR \<30 ml/kg/min, serum creatinine ≥ 2.5 mg/dL or on dialysis).
  • Aorto-ostial lesion location within 3 mm of the aorta junction (both right and left).
  • Vessel(s) and lesion(s) not amenable for evaluation with a PressureWire™ and/or revascularization.
  • Tandem lesions
  • Moderate lesions in patients with multivessel disease in whom at least one lesion in another major epicardic vessel is severe (to minimize lesion interaction), unless the severe lesion is treated first (see above).
  • Left ventricular ejection fraction \<50%
  • Known severe left ventricular hypertrophy
  • Atrial fibrillation or any other significant arrhythmia (including an heart rate \<50/min on sinus rhythm)
  • Systolic blood pressure \<90 mmHg.
  • Any other medical condition that in the opinion of the investigator will interfere with patient safety or study results
  • Currently participating in another clinical study that interferes with study results.
  • Pregnant or nursing females
  • Planned or prior heart transplantation or listed for heart transplant.
  • Any condition that precludes the subject from undergoing PCI or any of the protocol mandated procedures, for example subjects with a prior history heparin induced thrombocytopenia, known intolerance to adenosine or with a contra-indication for dual anti-platelet therapy.
