RESUMO

(1) Background: Segmented Cartesian Cardiovascular magnetic resonance (CMR) often fails to deliver robust assessment of cardiac function in patients with arrhythmia. We aimed to assess the performance of a tiny golden-angle spiral real-time CMR sequence at 1.5 T for left-ventricular (LV) volumetry in patients with irregular heart rhythm; (2) Methods: We validated the real-time sequence against the standard breath-hold segmented Cartesian sequence in 32 patients, of whom 11 presented with arrhythmia. End-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), and ejection fraction (EF) were assessed. In arrhythmic patients, real-time and standard Cartesian acquisitions were compared against a reference echocardiographic modality; (3) Results: In patients with sinus rhythm, good agreements and correlations were found between the segmented and real-time methods, with only minor, non-significant underestimation of EDV for the real-time sequence (135.95 ± 30 mL vs. 137.15 ± 31, p = 0.164). In patients with arrhythmia, spiral real-time CMR yielded superior image quality to the conventional segmented imaging, allowing for excellent agreement with the reference echocardiographic volumetry. In contrast, in this cohort, standard Cartesian CMR showed significant underestimation of LV-ESV (106.72 ± 63.51 mL vs. 125.47 ± 72.41 mL, p = 0.026) and overestimation of LVEF (42.96 ± 10.81% vs. 39.02 ± 11.72%, p = 0.039); (4) Conclusions: Real-time spiral CMR improves image quality in arrhythmic patients, allowing reliable assessment of LV volumetry.

RESUMO

Chronic total occlusion (CTO) of coronary arteries is a common finding in patients with known or suspected coronary artery disease (CAD). Although tremendous advances have been made in the interventional treatment of CTOs over the past decade, correct patient selection remains an important parameter for achieving optimal results. Non-invasive imaging can make a valuable contribution. Ischemia and viability, two major factors in this regard, can be displayed using echocardiography, single-photon emission tomography, positron emission tomography, computed tomography, and cardiac magnetic resonance imaging. Each has its own strengths and weaknesses. Although most have been studied in patients with CAD in general, there is an increasing number of studies with positive preselectional factors for patients with CTOs. The aim of this review is to provide a structured overview of the current state of pre-interventional imaging for CTOs.

RESUMO

Introduction: Takotsubo cardiomyopathy (TCM) is frequently associated with emotional or physical stress. Thus, patients with TCM might present primarily at a psychiatric clinic. Appropriate diagnosis and therapy may thus be delayed. Case report: A 43-year-old female patient presented as an emergency to the psychiatric outpatient clinic after experiencing severe work-related bullying. On admission, she complained of acute left thoracic chest pain as well as depressed mood, low energy, anhedonia, generalized anxiety, and sleep difficulties, present for several weeks. The initial electrocardiogram (ECG) was unremarkable; serum troponin levels, however, were markedly elevated. The patient was transferred to the department of cardiology. Via cardiac catheterization and MRI, an acute coronary syndrome was excluded and apical ballooning and left ventricular dysfunction, compatible with TCM, was found. Conclusion: Patients with acute psychopathology, recent emotional or physical stress, and acute cardiothoracic symptoms should receive immediate cardiological investigations. As the ECG may be normal in patients with TCM, concurrent measurement of the troponin serum level is recommended. Psychiatrists should consider TCM in patients who report recent stressful events accompanied by cardiothoracic symptoms.
