Italian registry of cardiac magnetic resonance.

OBJECTIVES: Forty sites were involved in this multicenter and multivendor registry, which sought to evaluate indications, spectrum of protocols, impact on clinical decision making and safety profile of cardiac magnetic resonance (CMR). MATERIALS AND METHODS: Data were prospectively collected on a 6-month period and included 3376 patients (47.2 ± 19 years; range 1-92 years). Recruited centers were asked to complete a preliminary general report followed by a single form/patient. Referral physicians were not required to exhibit any specific certificate of competency in CMR imaging. RESULTS: Exams were performed with 1.5T scanners in 96% of cases followed by 3T (3%) and 1T (1%) magnets and contrast was administered in 84% of cases. The majority of cases were performed for the workup of inflammatory heart disease/cardiomyopathies representing overall 55.7% of exams followed by the assessment of myocardial viability and acute infarction (respectively 6.9% and 5.9% of patients). In 49% of cases the final diagnosis provided was considered relevant and with impact on patient's clinical/therapeutic management. Safety evaluation revealed 30 (0.88%) clinical events, most of which due to patient's preexisting conditions. Radiological reporting was recorded in 73% of exams. CONCLUSIONS: CMR is performed in a large number of centers in Italy with relevant impact on clinical decision making and high safety profile.
