Reverse Takotsubo Cardiomyopathy As a Complication of MOG-antibody-associated Disease (MOGAD)? A Case Report

Efficacy of intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) is strongly time dependent in acute stroke management. We investigated the impact of a direct magnetic resonance imaging (MRI) room admission protocol in order to reduce in-hospital delays.We implemented a protocol of direct MRI room admission, bypassing the Emergency Department. We compared in-hospital delays, clinical and functional outcomes using National Institute of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) scores, between patients hospitalized via this protocol and those admitted via the standard workflow and treated by IVT and/or MT. The primary endpoint was the proportion of patients with door-to-needle time (DTN) ≤ 60 minutes.Among 308 consecutive patients included, 62 underwent direct MRI room admission. The proportion of patients with DTN ≤ 60 minutes was higher in the intervention group compared to the control group (82.5% vs. 17.8%, P < 0.001), and median DTN was lower (45 min vs. 75 min, P < 0.001). Despite a functional benefit at discharge on dichotomized mRS (mRS [0-2, as independence]: 66.1% vs. 51.2%, P = 0.003), the difference was no longer statistically significant at six months (68.4% vs. 57.4%, P = 0.10).Direct MRI room admission of stroke alerts is associated with an important reduction of treatment times and improves functional outcomes.
