Stellenwert der kardialen MRT bei Patienten mit ventrikulären Arrhythmien und zur Prävention des plötzlichen Herztods

Zusammenfassung

Die kardiovaskuläre Magnetresonanztomografie (CMR) hat nicht nur einen besonderen Stellenwert als Diagnostikum, sondern auch eine zunehmende Bedeutung hinsichtlich therapeutischer Entscheidungen bei Patienten mit ventrikulären Arrhythmien und in der Prävention des plötzlichen Herztods.

Die Übersichtsarbeit diskutiert auf Grundlage der aktuellen ESC-Leitlinie die Rolle der CMR in diesem Anwendungsbereich mit besonderem Fokus auf die dilatative, hypertrophe und arrhythmogene Kardiomyopathie sowie auf Patienten im chronischen Stadium nach einem Myokardinfarkt. Darüber hinaus werden entsprechende MRT-Basistechniken und Protokolle dargestellt sowie ein Ausblick hinsichtlich zu erwartender Studienergebnisse und aktuell bestehender Wissenslücken präsentiert.

Abstract

Cardiovascular magnetic resonance (CMR) has not only a special value as a diagnostic tool, but also an increasing importance regarding therapeutic decision making in patients with ventricular arrhythmias and in the prevention of sudden cardiac death. Based on the current 2022 ESC guideline, this review discusses the role of CMR in this field of application with a special focus on dilated, hypertrophic, and arrhythmogenic cardiomyopathy as well as on patients in the chronic stage after myocardial infarction. In addition, relevant basic MRI techniques and protocols are presented, as well as an outlook regarding expected study results and currently existing knowledge gaps.
