CANARY: Coronary Assessment by Near-infrared of Atherosclerotic Rupture-prone Yellow

Stopped early · Not applicable

Conditions studied: Coronary Atherosclerosis, Myocardial Infarction, Coronary Plaque Embolization

In brief

The CANARY (Coronary Assessment by Near-infrared of Atherosclerotic Rupture-prone Yellow) Study is a pivotal trial to evaluate criteria for defining a Lipid Core Plaque (LCP) that is at high risk of rupturing during standard of care therapy and causing intra-procedural complications. If plaques that require treatment are at higher than normal risk of causing intra-procedural complications, some life threatening, the treating physician is better informed and may opt to take precautionary measures to mitigate the risk or result of a complication. The CANARY Study is also designed to evaluate the feasibility of using a distal embolization protection device (EPD) as a means to prevent heart attacks triggered by the embolization of plaque during standard care therapy. It is thought that the EPD will prevent plaque from going downstream during treatment and obstructing other heart vessels. These obstructions could cause heart attacks by preventing blood from reaching heart muscle tissue.
