简要总结

This clinical study has been developed to evaluate the clinical outcomes in patients undergoing coronary artery bypass grafting via Minimally Invasive Coronary Surgery (MICS); a minimally invasive coronary bypass procedure that is done on a beating heart via a smaller chest incision, thus avoiding the invasiveness of the standard procedure.

结局指标

主要结局

Technical Success (Graft Patency) in a MICS Approach

时间窗: At time of procedure (day 1)

For each subject, the endpoint for technical success (graft patency) in a MICS approach is defined as acceptable flow for graft size for an anastamosis. This will be characterized by the surgeon's assessment/angiography after the graft is complete.

Patency of the Index Graft at 6 Months

时间窗: 6 months post-procedure

For each subject, the endpoint is the percent of stenosis collected on the subject's 6 month angiography form. This will be characterized for each graft using the FitzGibbon scoring system based on the 64-Slice CT Angiography results. The FitzGibbon Scoring system is as follows: A:Excellent graft with unimpaired runoff (\< 50% stenosis) B:Stenosis reducing caliber of proximal or distal anastomoses or trunk to \<50% of the grafted coronary artery. O:Occluded (100% stenosed)

Procedural Success in a MICS Approach

时间窗: At time of procedure (day 1)

A successful procedure can be defined as a procedures not requiring conversion (sternotomy). This will be characterized by whether the graft procedure can be completed through the minimally invasive thoracotomy without having to convert to a sternotomy in order to complete the grafting.

Composite Major Adverse Event Rate (Early)

时间窗: During procedure (day 1) and within 30 days post-procedure or hospital discharge, whichever is longer (throughout 6 month evaluation)

During procedure and within 30 days post-procedure or hospital discharge, whichever is longer. The adverse events will include: * Major hemorrhage/bleeding requiring surgical intervention * Aortic complications * Graft vessel revision (GVR) * Transient ischemic attacks (TIA) * Cerebrovascular accidents (CVA)/stroke * Myocardial infarction (MI) * Death

次要结局

  • Composite Major Adverse Event Rate (Late)(After 30 days post-procedure or hospital discharge, whichever is longer through the 6-Month evaluation)
