Magnetic resonance imaging in patients with a pacemaker system designed for the magnetic resonance environment

Role of the lead structure in MRI‐induced heating: In vitro measurements on 30 commercial pacemaker/defibrillator leads

“…Naehle et al (34) safely completed 18 MRI scans on non-PM-dependent ICD patients at 1.5 T: no significant changes of pacing capture threshold, lead impedance, and serum marker were observed. Recently, the first clinical trials for the evaluation of the safety and the effectiveness of PM systems designed for safe use in MRI have been published (6): no MRI-related complications during or after MRI were reported.…”

“…The results of these studies demonstrated that the devices in use today may be more resistant to changes in function during an MR examination. To date, data on more than 1000 patients who underwent clinically driven MRI are available (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11). Even if some adverse events were observed (11), in most cases no serious injuries have been reported in physician-supervised MRI studies during which the patients were carefully monitored, and only minor effects were observed (minor changes in pacing threshold, the need for device reprogramming, possibly battery depletion).…”

2013 ESC Guidelines on Cardiac Pacing and Cardiac Resynchronization Therapy

“…Un reciente ensayo clínico internacional, prospectivo, aleatorizado y controlado 173 , que incluyó a 258 pacientes aleatorizados a cardio-RM durante un periodo de 1,5 años, evaluó la seguridad y la eficacia de un sistema de marcapasos diseñado para uso seguro en cardio-RM para todo paciente con indicación por bradicardia. No ocurrió complicación alguna relacionada durante la cardio-RM a 1,5 T ni tras 1 semana y 1 mes de la intervención.…”

Wytyczne ESC dotyczące stymulacji serca i terapii resynchronizującej w 2013 roku

“…W ostatnim prospektywnym, randomizowanym, kontrolowanym, przeprowadzonym na całym świecie badaniu klinicznym [173] obejmującym 258 pacjentów randomizowanych do wykonania MRI w ciągu 1,5 roku oceniono bezpieczeństwo i efektywność PM stosowanych w celach przeciwbradyarytmicznych i przeznaczonych do bezpiecznego wykonania MRI. Nie wystąpiły żadne powikłania związane z wykonaniem badania MRI przy użyciu 1,5 T, ani po tygodniu, ani po miesiącu po badaniu.…”
