It is very important to underline that this is a "spontaneous" study, i.e. not receiving sponsorship from pharmaceutical industries, stent manufacturers, or any other financial source. This independence from economic interests would contribute to exclude conflicts of interest that may bias the results of the study that is aimed at testing the applicability and the clinical efficacy of this therapy. Furthermore, the assessment of the DES in public hospitals, and beyond the spectrum of the industry-supported studies may offer interesting results of the real life use of these devices.
