Implantable Defibrillator System Shock Function, Mortality, and Cause of Death After Magnetic Resonance Imaging">January 31, 2023Studies have shown that magnetic resonance imaging (MRI) does not have clinically important effects on the device parameters of non–MRI-conditional implantable cardioverter-defibrillators (ICDs). However, data on non–MRI-conditional ICD detection and treatment of arrhythmias after MRI are limited.
During a median follow-up of 2.2 years from MRI to latest available ICD interrogation before generator or lead exchange in 536 patients, 4177 arrhythmia episodes were detected, and 97 patients received ICD shocks. Sixty-one patients (10% of total) had 130 spontaneous ventricular tachycardia or fibrillation events terminated by ICD shocks. A total of 210 patients (33% of total) are known to have died (median, 1.7 years from MRI to death); 3 had cardiac arrhythmia deaths where shocks were indicated without direct evidence of device dysfunction.
Conclusion:
Non–MRI-conditional ICDs appropriately treated detected tachyarrhythmias after MRI. No serious adverse effects on device function were reported after MRI.

Total Ankle Replacement Versus Arthrodesis for End-Stage Ankle Osteoarthritis">Total Ankle Replacement Versus Arthrodesis for End-Stage Ankle Osteoarthritis
Total Ankle Replacement Versus Arthrodesis for End-Stage Ankle Osteoarthritis">December 31, 2022End-stage ankle osteoarthritis causes severe pain and disability. There are no randomized trials comparing the 2 main surgical treatments: total ankle replacement (TAR) and ankle fusion (AF).
Between 6 March 2015 and 10 January 2019, a total of 303 patients were randomly assigned. At 52 weeks, the scores improved for both groups. The adjusted difference showed that TAR improved more than AF, but the difference was not considered clinically or statistically significant. The number of adverse events was similar between groups, but there were more wound healing issues in the TAR group and more thromboembolic events and nonunion in the AF group. The symptomatic nonunion rate for AF was 7%. A post hoc analysis suggested superiority of fixed-bearing TAR over AF.
