What was the result of the coronary stenting procedure?

The result of the coronary stenting procedure being described as "no residual stenosis" indicates that the procedure was effective in relieving the blockage that was present in the coronary arteries. During a coronary stenting, a small mesh tube is inserted into a narrowed artery to keep it open and ensure adequate blood flow. The goal of this intervention is to alleviate any restrictions caused by plaque buildup or other forms of occlusion.

Achieving "no residual stenosis" means that post-procedure, the artery has been successfully widened to a point where blood can flow freely without significant constriction. This outcome is significant because it reduces the risk of future cardiovascular events, such as heart attacks, which can occur due to insufficient blood supply to the heart muscle. Thus, it underscores the efficacy of the coronary stenting in addressing the health issues related to coronary artery disease.

In contrast, the other outcomes would indicate varying degrees of inefficacy or complications associated with the procedure, such as unsuccessful stent placement or remaining occlusion, which would not provide the desired therapeutic benefit.
