๐จย New Interventional Cardiology Trial Alert: PROCTOR Study Results
In patients with prior CABG and failing saphenous vein grafts (SVGs), the choice of which vessel to re-intervene on is a common dilemma. The just-publishedย PROCTOR trialย provides compelling evidence.
โกย The Study:ย Randomized 220 post-CABG patients with SVG failure to receive PCI either on theย native coronary arteryย (108 pts) or on theย saphenous vein graftย itself (112 pts).
โกย Key Finding at 1 Year:ย PCI on theย native artery was associated with worse outcomesย than PCI on the SVG.
Major Adverse Cardiac Events:ย 34% (native) vs. 19% (SVG) | HR 2.14
Nonfatal MI:ย Significantly higher with native PCI | HR 2.12
Repeat Revascularization:ย Higher with native PCI | HR 2.19
PCI-Related MI:ย 13% (native) vs. 1% (SVG) | HR 14.85
Mortality:ย No significant difference.
Conclusion:ย In this population,ย SVG PCI produced significantly better one-year clinical outcomesย than attempting native vessel PCI.
This challenges some conventional wisdom and underscores the complexity of managing post-CABG patients.ย It highlights that technical success in a native vessel does not always translate to better patient outcomes, possibly due to vessel quality, complexity, and collateral flow.

Acronym Definitions:
PCI:ย Percutaneousย Coronaryย Intervention. A minimally invasive procedure to open blocked coronary arteries, typically using a balloon and stent.
SVG:ย Saphenousย Veinย Graft. A segment of the leg vein used during CABG surgery to bypass a blocked coronary artery.
CABG:ย Coronaryย Arteryย Bypassย Grafting. Open-heart surgery to restore blood flow by grafting vessels to bypass coronary blockages.
MI:ย Myocardialย Infarction. A heart attack, caused by a blockage of blood flow to the heart muscle.
HR:ย Hazardย Ratio. A measure of how often an event happens in one group compared to another over time in a study. An HR >1.0 indicates a higher risk.
PROCTOR:ย (Trial Name) Likely an acronym related to the trial’s focus (e.g.,ย PCI ofย Restenoticย Occludedย Coronary naTive arteries versus bypass grafts), though the full expansion is not standardized in the summary provided.
