Fifty-three patients (34 who had diffuse scleroderma, and 19 who had CREST syndrome [calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasias]) were studied by noninvasive procedures, including resting electrocardiogram (ECG), continuous 24-hour Holter ECG monitoring, M-mode echocardiography, and 2-dimensional echocardiography. Only 22 patients (42%) had abnormalities such as conduction defects, supraventricular or ventricular arrhythmias, or ST-T changes detected on resting ECG. In contrast, using Holter monitoring, the number of conduction abnormalities seen increased from 10 to 16 patients and transient ST-T changes increased from 2 to 18 patients. Forty-eight patients had ventricular arrhythmias, with multiform ventricular premature beats in 21 (40%), pairs of runs of ventricular tachycardia in 15 patients (28%), and 1 or more runs of ventricular tachycardia in 7 (13%). Echocardiography detected asymmetric septal hypertrophy in 10 patients, impaired ventricular function in 9 patients, congestive cardiomyopathy in 2, mitral prolapse in 4, and pericardial effusion in 3 patients. Multiform and/or repetitive ventricular premature beats occurred more frequently in patients with echocardiographic abnormalities, but were also present in patients who had normal findings on echocardiographic examination. Cardiac involvement was not correlated with clinical variants of scleroderma (CREST syndrome or diffuse scleroderma), nor with other signs and symptoms of the disease. Thus, cardiac involvement is found much more frequently than would be expected from clinical symptoms or from results of resting ECG alone; therefore, Holter monitoring and echocardiography should be included in the routine workup of patients who have scleroderma.

Atherosclerotic carotid artery stenosis (CS) continues to be a common cause of acute ischaemic stroke. Optimised medical therapy (OMT), the first-line treatment modality in CS, may reduce or delay - but it does not abolish - CS-related strokes. As per current AHA/ASA and ESC/ESVS/ESO guidelines, carotid artery stenting (CAS) is a less-invasive alternative to carotid endarterectomy (CEA) for CS revascularisation in primary and secondary stroke prevention. Ten-year follow-up from the CREST trial in patients with symptomatic and asymptomatic CS confirmed equipoise of CAS and CEA in the primary endpoint. Nevertheless CAS - using a widely open-cell, first-generation stent and first-generation (distal/filter) neuroprotection - has been criticised for its relative excess of (mostly minor) strokes by 30 days, a significant proportion of which were post-procedural. Atherosclerotic plaque protrusion through conventional carotid stent struts, confirmed on intravascular imaging, has been implicated as a leading mechanism of the relative excess of strokes with CAS vs. CEA, including delayed strokes with CAS. Different designs of mesh-covered carotid stents have been developed to prevent plaque prolapse. Several multi-centre/multi-specialty clinical studies with CGurad MicroNet-Covered Embolic Prevention Stent System (EPS) and RoadSaver/Casper were recently published and included routine DW-MRI cerebral imaging peri-procedurally and at 30 days (CGuard EPS). Data from more than 550 patients in mesh-covered carotid stent clinical studies to-date show an overall 30-day complication rate of ~1% with near-elimination of post-procedural events. While more (and long-term) evidence is still anticipated, these results - taken together with optimised intra-procedural neuroprotection in CAS (increased use of proximal systems including trans-carotid dynamic flow reversal) and the positive 12-month mesh-covered stent data reports in 2017 - are transforming the carotid revascularisation field today. Establishing effective algorithms to identify the asymptomatic subjects at stroke risk despite OMT, and large-scale studies with mesh-covered stents including long-term clinical and duplex ultrasound outcomes, are the next major goals.
