The statement regarding stents being the same in mechanism of action as angioplasty is accurate. Stenting and angioplasty are related interventions but have distinct mechanisms. Angioplasty involves the inflation of a balloon within a narrowed artery to open it up, whereas stents are used to provide structural support to the artery after it has been dilated by angioplasty. This support helps to prevent the artery from collapsing again and reduces the risk of re-narrowing.

Stents are typically deployed in conjunction with angioplasty, but their role goes beyond merely expanding the vessel, as they also serve to maintain vessel patency over time. Understanding the difference between the two mechanisms is crucial for effective vascular intervention practice.

The other statements about stents are accurate: stents can be employed during percutaneous coronary interventions, they can come in various designs such as closed or open-celled configurations, and the choice of metal in stent construction does have a significant influence on how effectively the stent functions clinically. This distinction ensures that clinicians can select the appropriate device based on the specific needs of the patient and the characteristics of their vascular condition.
