In 2010 the International Atomic Energy Agency launched the "3 A's campaign": Audit, Appropriateness and Awareness for radiological justification, which is an effective tool for cancer prevention. Cardiologists prescribe the majority of radiological testing, but their awareness of doses and risks of ionizing cardiac imaging test is low. To assess radioprotection awareness of prescribing and practicing physicians (mainly cardiologists) before and after a radioprotection course. We held a 1-day 6-h primer of radioprotection for a limited number (20-35) of physicians. The course offered 8 continuing education credits from the Italian Health Ministry and was held 9 times over 3 years. We had 425 attendees, but full data sets (with complete questionnaires) were available for 403 physicians (55% women, age 45 ± 6 years), including 55% cardiologists, 40% general practitioners, 5% others (mainly cardiology fellows). For each attendee, a radiological awareness score was obtained before and after the course, with a survey containing 10 multiple-choice questions (5 answers) on radioprotection basics (doses of common examinations in multiples of chest x-rays; associated cancer risk, etc.). Each answer was scored from 0 ("don't know"), 1 ("strongly disagree") to 4 ("strongly agree"). The radiological awareness score of the 403 attendees improved from 31 ± 3 (before) to 37 ± 2 (after training, P < 0.001 vs. pre-training). As an example, before training, 25% of attendees believed that radiation-induced cancer risk disappears after 6 months (10% of respondents), 12 months (8%) or 5 years (7%), whereas 75% (becoming 98% after training) correctly estimated that radiological damage is cumulative over one's lifetime. Awareness of radiological doses and risks, albeit essential for risk-benefit assessment of radiological testing, is suboptimal among cardiologists, but can dramatically improve with a limited teaching effort through targeted training.

In recent years, percutaneous placement of stents has been used as an alternative to surgery or balloon angioplasty for the treatment of adults with peripheral pulmonary arterial stenosis. This therapy has also been proposed for children, but questions still remain about its indications in this group of patients. We describe here the results of intravascular placement of stents in a group of 29 patients, with a mean age of 12+/-7 (range 3-31) years and weighing 35+/-19 (range 11-74) kg. All were affected by postsurgical or congenital isolated pulmonary arterial stenosis, and have now been followed for 38+/-19 (range 6-65) months. The early hemodynamic results have been excellent, with a significant reduction of the pulmonary arterial systolic pressure, the systolic pressure gradient, and the ratio of systolic pressures in the pulmonary and systemic circuits, and with a significant increase of the diameter of the stented vessels in all the patients. Of the 29 patients, 24 have been recatheterized 18+/-10 months after the procedure, demonstrating the stability of the results, with a low incidence of late restenosis, this seen in only 1 patient (2%). Lung perfusion scanning, performed in 17 patients each year after the follow-up catheterization, has showed that the results are maintained at long-term follow-up (51+/-9 months).

This paper describes the electronic medical record (EMR) we have developed for use in our health care institution, mainly dealing with diagnosis and treatment of cardiovascular pathologies. This activity was part of the project SPERIGEST, supported by Health Ministry of Italy, for the management (clinical and administrative) of health care delivery. A networked information infrastructure was realized to integrate the direrent sources of patient information. Both clinical and administrative relevant data are collected from the various systems and stored into a central database. The EMR system was realised using World Wide Web (www) technology. The system is currently evaluated in one of the clinical departments of our institute.
