COronary SInus Reducer in Patients With Refractory Angina II
open to eligible people ages 18 years and up
To demonstrate the safety and effectiveness of the Reducer system for treatment of patients with refractory angina pectoris treated with maximally tolerated guideline-directed medical therapy who demonstrate objective evidence of reversible myocardial ischemia in the distribution of the left coronary artery and who are deemed unsuitable for revascularization. A non-randomized single-arm will further assess the safety and effectiveness of the Neovasc Reducer System in selected subjects with reversible myocardial ischemia in the distribution of the right coronary artery and who are deemed unsuitable for revascularization, subjects with reversible myocardial ischemia without documented obstructive coronary disease and subjects who cannot complete an exercise tolerance test due to an above-the-ankle amputation.

Novel Non-Invasive Automated Fractional Flow Reserve Software System in Patients With Coronary Artery Disease
Sorry, in progress, not accepting new patients
This retrospective study will evaluate the coronary angiograms of approximately 100 patients who have undergone invasive angiography and fractional flow reserve (FFR). DICOM files of the angiograms will be analyzed on a secure computer within the cardiac catheterization laboratory using the AutocathFFR software to assess if invasive FFR measurements and automated computer analysis of FFR measurements correlate. AutocathFFR measurement per lesion will be compared to the gold standard, invasive FFR value, where an FFR ≤ 0.80 will be considered "positive", while an FFR > 0.8 will be considered "negative". The AutocathFFR value will be compared to the invasive FFR measurements. The sensitivity and specificity of the AutocathFFR will be calculated, as well as the AutocathFFR accuracy, positive predictive value and negative predictive value per lesion. Device success will be calculated as the ratio of completed versus initiated AutocathFFR index calculations. Usability of the AutocathFFR software will be evaluated using dedicated questionnaires to be completed by the user (cardiologists).
