: Aortic floating thrombus (AFT) is a rare disease, which is often misdiagnosed as a tumor or another disease. Here, we report five cases of AFT, confirmed by computed tomography angiography (CTA). The patients’ laboratory biomarkers, clinical treatment, dynamic changes, and CTA features, including the AFT location, morphology, size, and aortic segment involvement, were retrospectively analyzed. CTA was the main imaging modality for detecting AFT, as it could depict lesions and determine the therapeutic effects accurately. Overall, the therapeutic strategy should be selected individually, depending on the patient’s physical health; conservative medication use is also recommended.

Rationale About one-third of ischaemic strokes are caused by cardioembolism, and a substantial proportion of cryptogenic strokes likely also originate from the heart or aortic arch. Early determination of aetiology is important to optimise management. Computed Tomography-angiography of the heart is emerging as an alternative to echocardiography to detect cardio-aortic sources of embolism in stroke patients, but its diagnostic yield in acute ischaemic stroke has not been thoroughly assessed. Hypothesis: We hypothesise that electrocardiography-gated computed tomography-angiography of the heart and aortic arch, acquired in the acute phase in patients with ischaemic stroke, has a higher diagnostic yield than transthoracic echocardiography as a first-line screening method for detection of cardio-aortic sources of embolism. Methods and design Mind the Heart is a single-centre prospective observational cohort study. We will include consecutive adult patients with acute ischaemic stroke who are potentially eligible for reperfusion therapy. Patients undergo non-electrocardiography-gated computed tomography-angiography of the aortic arch, cervical and intracranial arteries, directly followed by prospective sequential electrocardiography-gated cardiac computed tomography-angiography. Routine work-up for cardioembolism including 12-leads electrocardiography, Holter electrocardiography and transthoracic echocardiography is performed as soon as possible. The primary endpoint is the proportion of patients with a predefined high-risk cardio-aortic source of embolism on computed tomography-angiography versus transthoracic echocardiography in patients who underwent both investigations. Based on an expected 5% additional yield of computed tomography-angiography, a sample size of 450 patients is required. Conclusions The Mind the Heart study will generate a reliable estimate of the diagnostic yield of echocardiography-gated cardio-aortic computed tomography-angiography performed in the acute phase of ischaemic stroke.

Abstract Background: Critical aortic coarctation is defined as the severe narrowing of the isthmic aortic lumen, representing a neonatal cardiac emergency, part of the congenital heart diseases with duct-dependent systemic circulation. Aim of the study: To assess the correlation between transthoracic echocardiography and computed tomography angiography (CTA) in the measurement of aortic diameters in a group of newborns diagnosed with duct-dependent aortic coarctation and/or associated hypoplastic aortic arch. Material and method: We performed a retrospective study on neonates diagnosed with duct-dependent aortic coarctation and/or associated hypoplastic aortic arch between January 1, 2015 and March 1, 2017. The studied parameters were diameters of the aorta at the level of the aortic annulus, coronary sinuses, sinotubular junction, ascending aorta, proximal and distal aortic arch, and the aortic isthmus. Measurements were obtained by transthoracic echocardiography and thoracic CTA. Results: Fifteen newborns diagnosed with duct-dependent aortic coarctation and/or associated hypoplastic aortic arch were included in this study. There was no statistically significant difference between the two imaging methods, the T test highlighting differences only between the measurements of the aortic annulus (p <0.016) and coronary sinuses (p <0.008). The patients included in the study associated other cardiovascular abnormalities: persistent ductus arteriosus (100%), atrial septal defect (100%), aortic arch hypoplasia (80%), bicuspid aortic valve (73.3%). Conclusions: These methods reveal important information on the anatomy of the cardiovascular malformation and its impact on the clinical and paraclinical status of the patient, being fundamental for establishing an optimal therapeutic approach.
