Prevalence and Disease Spectrum of Extracoronary Arterial Abnormalities in Spontaneous Coronary Artery Dissection.

JAMA Cardiol 2021 Nov 24. Epub 2021 Nov 24.

Department of Cardiovascular Sciences, University of Leicester, NIHR Leicester Biomedical Research Centre, Glenfield Hospital, Leicester, United Kingdom.

Importance: Spontaneous coronary artery dissection (SCAD) has been associated with fibromuscular dysplasia (FMD) and other extracoronary arterial abnormalities. However, the prevalence, severity, and clinical relevance of these abnormalities remain unclear.

Objective: To assess the prevalence and spectrum of FMD and other extracoronary arterial abnormalities in patients with SCAD vs controls.

Design, Setting, And Participants: This case series included 173 patients with angiographically confirmed SCAD enrolled between January 1, 2015, and December 31, 2019. Imaging of extracoronary arterial beds was performed by magnetic resonance angiography (MRA). Forty-one healthy individuals were recruited to serve as controls for blinded interpretation of MRA findings. Patients were recruited from the UK national SCAD registry, which enrolls throughout the UK by referral from the primary care physician or patient self-referral through an online portal. Participants attended the national SCAD referral center for assessment and MRA.

Exposures: Both patients with SCAD and healthy controls underwent head-to-pelvis MRA (median time between SCAD event and MRA, 1 [IQR, 1-3] year).

Main Outcome And Measures: The diagnosis of FMD, arterial dissections, and aneurysms was established according to the International FMD Consensus. Arterial tortuosity was assessed both qualitatively (presence or absence of an S curve) and quantitatively (number of curves ≥45%; tortuosity index).

Results: Of the 173 patients with SCAD, 167 were women (96.5%); mean (SD) age at diagnosis was 44.5 (7.9) years. The prevalence of FMD was 31.8% (55 patients); 16 patients (29.1% of patients with FMD) had involvement of multiple vascular beds. Thirteen patients (7.5%) had extracoronary aneurysms and 3 patients (1.7%) had dissections. The prevalence and degree of arterial tortuosity were similar in patients and controls. In 43 patients imaged with both computed tomographic angiography and MRA, the identification of clinically significant remote arteriopathies was similar. Over a median 5-year follow-up, there were 2 noncardiovascular-associated deaths and 35 recurrent myocardial infarctions, but there were no primary extracoronary vascular events.

Conclusions And Relevance: In this case series with blinded analysis of patients with SCAD, severe multivessel FMD, aneurysms, and dissections were infrequent. The findings of this study suggest that, although brain-to-pelvis imaging allows detection of remote arteriopathies that may require follow-up, extracoronary vascular events appear to be rare.

[Extra-cardiac findings on coronary computed Tomography scanning].

Tunis Med 2012 May;90(5):394-6

Service D'Imagerie Médicale, Hôpital la Rabta, Faculté de Médecine de Tunis, Université Tunis El Manar.

Background: Multi-detector-row computed tomography (MDCT) has emerged as method for non-invasive imaging of the heart.

Aim: To investigate the frequency of the non cardiac findings in cardiac imaging with MDCT.

Methods: A total of 191 patients underwent cardiac imaging with 64-slice MDCT over a period of 8 months. The detected abnormalities were classified in major (implying an immediate workup and treatment or at least a further investigation) and minor abnormalities.

Results: Extra cardiac abnormalities were detected on 69 examinations (36 %). Major abnormalities were found in 17 % of the patients, and the minor abnormalities in 25,6 %. The scan revealed 4 cases of lung carcinomas, all at a still surgical stage.

Conclusion: There were a significant number of non cardiac findings in cardiac MDCT. To avoid missing clinically important findings, we should carefully evaluate all the organs included in the scan.
