Abstract
Patient characteristics, higher device cost, and vendor contracts likely prevent use of magnetic resonance imaging (MRI)-conditional pacemakers (MRC) in all pacemaker (PM)-eligible patients. We sought to identify the incidence and predictors of MRI scan utilization in MRC recipients. Patients receiving an MRC or non-MRI-conditional PM (NMRC) at four centers were included. Incidence of MRI scans following PM insertion was obtained from hospital records and patient phone calls. Of 1,244 patients (74 ± 12 years, 54.6% male), 927 had MRC and 317 had NMRC. At baseline, MRC recipients had a higher incidence of atrial tachycardia and MRI risk factors (syncope, recurrent falls, neurological disease, severe musculoskeletal disease, malignancy). In the MRC group, more patients had commercial health insurance (26% vs 15%, P < 0.001). Sixty MRC patients (6.5%) had an MRI during 21 ± 17 months' follow-up. Using the Weilbull parametric survival model, the projected percentage of MRC patients receiving an MRI scan at 7- and 11-year follow-up were 45% and 73%, respectively. By multivariate regression, a prior history of MRI (odds ratio [OR] 4.5, 95% confidence interval [CI] 2.2-9.1, P < 0.001) and active smoking (OR 2.65, 95% CI 1.1-6.7, P = ...Continue Reading
