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.

The purpose of this study is to assess if using the Impella® CP (or Impella® 2.5) device during high-risk PCI in patients with reduced left-sided heart function will result in an improvement in symptoms, heart function and health after a heart procedure compared to the current standard of care.

This prospective study is a multi-center early feasibility study assessing the safety and performance of the Aria CV Pulmonary Hypertension System in patients with pulmonary hypertension and right heart dysfunction.

Intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) has been shown in clinical trials, registries, and meta-analyses to reduce recurrent events after PCI. This is accomplished by improving the angiographic result with lesion and vessel assessment to guide stent selection and implantation and intravascular imaging following stent implantation to ensure an adequate treatment endpoint has been achieved.

Despite extensive literature supporting the use of IVUS in PCI, utilization remains low in the United States. An increasing number of high-risk or complex lesions are being treated with PCI and we hypothesize that the impact of IVUS in these complex lesions will be of increased importance in reducing clinical adverse events while remaining cost effective.

The objective of this trial is to evaluate the safety and effectiveness of the Amulet LAA occluder compared to NOAC therapy in patients with non-valvular AF at increased risk for ischemic stroke and who are recommended for long-term NOAC therapy.

The clinical investigation is a prospective, randomized, multicenter active control worldwide trial. Subjects will be randomized in a 1:1 ratio between the Amulet LAA occlusion device ("Device Group") and a commercially available NOAC medication ("Control Group"). The choice of NOAC in the Control Group will be left to study physician discretion.

Percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs) is increasingly being performed in patients with advanced coronary artery disease, but there is limited information on the techniques utilized and the procedural outcomes. The goal of this multicenter, investigator initiated registry is to collect information on treatment strategies and outcomes of consecutive patients undergoing CTO PCI among various participating centers.

The information collected will be used to determine the frequency of CTO PCI performed at the participating sites and examine the procedural strategies utilized, and the procedural (both immediate and during follow-up) outcomes.
