The implantation of latest generation drug-eluting stents represents one of the major therapeutic achievements of Cardiology. Without detracting from the advantages of this therapeutic solution, the presence of a foreign body in a coronary artery can be problematic in the long term (5-10 years) due to the tendency of the artery to form a plaque inside the stent and to the difficulties in treating a new narrowing within the stent itself.

Not infrequently, we see situations requiring the implantation of a stent inside another stent. These problems are magnified when using long stents. The possibility to obtain the same results without implanting foreign bodies is an interesting alternative.
