Cardiovascular diseases (CVD) affect the heart and surrounding blood vessels and can take many forms, such as high blood pressure, coronary artery disease, heart disease and stroke. CVD are the largest cause of death in the EU and account for approximately 40% of death or 2 million deaths per year. Invasive cardiology plays a major role of countering this trend with its main device: the stent.

A stent is a biocompatible wire metal mesh tube used to open the artery.

The executing and evaluating of the tasks outlined in title may help clinicians to provide fast and efficient patient care. For them and patients is a vital aspect to the imlpant placed into the right position, and this is essential to achive good visibility. This avoids the need for higher than normal number of stents implanted.

Experience in my daily work as a scrub nurse, the visibility of coronary stents currently in use is not appropriate. The interventions and with the X-ray period is unduly prolonged. Continuous screening - which can greatly reduce the lifetime of the X-ray tube - and unnecessarily large amount of contrast material enormous strain on the patients.

Taking all this into account, I consider it important that we developed a method that, knowing the visibility, it allows a higher standard of care for patients. Therefore I started a study about clinical examinations of implants to compare with the laboratory examinations.
