Clinical safety of cardiac magnetic resonance imaging at 3 T early after stent placement for acute myocardial infarction

Magnetic resonance in patients with cardiovascular devices. SEC-GT CRMTC/SEC-Heart Rhythm Association/SERAM/SEICAT consensus document

Magnetic resonance has become a first-line imaging modality in various clinical scenarios. The number of patients with different cardiovascular devices, including cardiac implantable electronic devices, has increased exponentially. Although there have been reports of risks associated with exposure to magnetic resonance in these patients, the clinical evidence now supports the safety of performing these studies under specific conditions and following recommendations to minimize possible risks. This document was written by the Working Group on Cardiac Magnetic Resonance Imaging and Cardiac Computed Tomography of the Spanish Society of Cardiology (SEC-GT CRMTC), the Heart Rhythm Association of the Spanish Society of Cardiology (SEC-Heart Rhythm Association), the Spanish Society of Medical Radiology (SERAM), and the Spanish Society of Cardiothoracic Imaging (SEICAT). The document reviews the clinical evidence available in this field and establishes a series of recommendations so that patients with cardiovascular devices can safely access this diagnostic tool.

Evidence-Based Practices in the Cardiac Catheterization Laboratory: A Scientific Statement From the American Heart Association

Cardiac catheterization procedures have rapidly evolved and expanded in scope and techniques over the past few decades. However, although some practices have emerged based on evidence, many traditions have persisted based on beliefs and theoretical concerns. The aim of this review is to highlight common preprocedure, intraprocedure, and postprocedure catheterization laboratory practices where evidence has accumulated over the past few decades to support or discount traditionally held practices.

Review of safety reports of cardiac MR-imaging in patients with recently implanted coronary artery stents at various field strengths

Background: Aim of this study was to review current literature and data regarding the effects of MRI-examination post stent implantation on re-occlusion rates.Methods: We focused on representative studies in the database MEDLINE. Inclusion criteria were: clinical studies with the main focus on the safety of coronary artery stents after MRI-examination in the time interval of 8 weeks post stent implantation. During a follow up period the incidence of cardiac events was recorded. In addition, the time interval between stent implantation and MRI-examination should be defined.Results: Our search resulted in a total of relevant 17 studies. There were in-vivo as well as in-vitro studies and in addition three further publications f.e. guidelines. Concerning the patients, we differentiated between MRI performed shortly after acute cardiac event and in stable CAD. MRI-examinations were performed at different field strengths and reported different stent types. Considered were the incidences of cardiac events.Conclusion: Independent of MRI field strength (1.5 Tesla or 3.0 Tesla) or used stent type (BMS or DES), there was no increased rate for cardiac events in patients, who underwent MRI < 8 weeks after stent placement. MRI < 8 weeks after stent placement seems to be safe.
