RESUMO
BACKGROUND: Diabetes mellitus (DM) is associated with a worse prognosis in patients with heart failure. Our aim was to analyze the clinical and imaging features of patients with DM and their association with outcomes in comparison to nondiabetic patients in a cohort of patients with nonischemic dilated cardiomyopathy (DCM). METHODS: This is a prospective cohort study of patients with DCM evaluated in a tertiary care center from 2018 to 2021. Transthoracic echocardiography and cardiac magnetic resonance findings were assessed. A high-risk late gadolinium enhancement (LGE) pattern was defined as epicardial, transmural, or septal plus free-wall. The primary outcome was a composite of heart failure hospitalizations and all-cause mortality. Multivariable analyses were performed to evaluate the impact of DM on outcomes. RESULTS: We studied 192 patients, of which 51 (26.6%) had DM. The median left ventricular ejection fraction was 30%, and 106 (55.2%) had LGE. No significant differences were found in systolic function parameters between patients with and without DM. E/e values were higher (15 vs. 11.9, p = 0.025), and both LGE (68.6% vs. 50.4%; p = 0.025) and a high-risk LGE pattern (31.4% vs. 18.5%; p = 0.047) were more frequently found in patients with DM. The primary outcome occurred more frequently in diabetic patients (41.2% vs. 23.6%, p = 0.017). DM was an independent predictor of outcomes (OR 2.01; p = 0.049) and of LGE presence (OR 2.15; p = 0.048) in the multivariable analysis. Patients with both DM and LGE had the highest risk of events (HR 3.1; p = 0.003). CONCLUSION: DM is related to a higher presence of LGE in DCM patients and is an independent predictor of outcomes. Patients with DM and LGE had a threefold risk of events. A multimodality imaging approach allows better risk stratification of these patients and may influence therapeutic options.

BACKGROUND: Reduction of variability through process reengineering can improve surgical results for patients with type A acute aortic syndrome. We compare short-term results before and after implementation of an Aorta Code for patients with type A acute aortic syndrome who underwent surgery. METHODS: The Aorta Code was implemented in a 5-hospital healthcare network in 2019. This critical pathway was based on a simple diagnostic algorithm, ongoing training, immediate patient transfer, and treatment by an expert multidisciplinary team. We retrospectively compared all patients operated on in our center before (2005-2018) and after (January 2019 to February 2023) its implementation. RESULTS: One hundred two and 70 patients underwent surgery in the precode and code periods, respectively. In the code period the number of patients operated on per year increased (from 7.3 to 16.8), and the median elapsed time until diagnosis (6.5 hours vs 4.2 hours), transfer (4 hours vs 2.2 hours), and operating room (2.7 hours vs 1.8 hours) were significantly shorter (P < .05). Aortic root repair and total arch replacement were more frequent (66.7% vs 82.9% [P = .003] and 20.6% vs 40% [P = .001]). Cardiopulmonary bypass and ischemia times were also shorter (179.7 minutes vs 148.2 minutes [P = .001] and 105 minutes vs 91.2 minutes [P = .022]). Incidence of prolonged mechanical ventilation (53.9% vs 34.3%, P = .011), major stroke (17.7% vs 7.1%, P = .047), and 30-day mortality (27.5% vs 7.1%, P = .001) decreased significantly. CONCLUSIONS: An Aorta Code can be successfully implemented by using a standardized protocol within a hospital network. The number of cases increased; time to diagnosis, transfer, and operating room were reduced; and 30- day mortality significantly decreased.

Some coronary artery anomalies are associated with increased risk of sudden cardiac death and myocardial infarction in young patients. There are few data on the clinical and prognostic relevance of isolated origin of the left circumflex artery from the pulmonary artery, an extraordinarily rare variant of anomalous left coronary artery from the pulmonary artery. (Level of Difficulty: Intermediate.).
RESUMO
Introducción y objetivos: Está demostrado que la tomografía computarizada con multidetectores (TCMD) es una alternativa factible a la coronariografía invasiva (CI). Sin embargo, se han indicado resultados contradictorios sobre el efecto de la puntuación de calcio (PC) coronario en la precisión diagnóstica de la TCMD. El objetivo de este estudio es evaluar la concordancia entre la TCMD y la CI y evaluar la influencia de la PC en ella. Métodos: Se incluyó a 266 pacientes consecutivos sometidos a evaluación por TCMD de 64 cortes y por CI. Se utilizó el software habitual para la PC mediante el método Agatston. Un observador clasificó cualitativamente y de manera enmascarada las estenosis como leve, moderada o grave, y se compararon con los resultados obtenidos por la CI, utilizada como método de referencia. Resultados: La media de edad de los pacientes era 65,4 ± 11,2 años, y 188 (70,3%) eran varones. Se evaluó cualitativamente y se cuantificó por TCMD un total de 484 segmentos con estenosis coronaria al menos leve. Las mediciones no invasivas concordaban con la CI en 402 estenosis (el 83,05%; kappa = 0,684), sin diferencias significativas entre vasos y sin una influencia estadística significativa de la PC en la concordancia (OR = 0,93; IC95%, 0,76-1,09; p = 0,21). La TCMD tuvo sensibilidad, especificidad, valor predictivo positivo y valor predictivo negativo altos en los análisis por segmento, por vaso y por paciente. Conclusiones: La coronariografía no invasiva mediante TCMD mostró buena concordancia con la CI en la cuantificación cualitativa de las estenosis coronarias, y la PC no tuvo un impacto significativo en esa concordancia (AU)
Introduction and objectives: Multidetector computed tomography (MDCT) has been demonstrated as a feasible alternative to invasive coronary angiography (ICA). However, contradictory results have been reported regarding the effect of coronary artery calcium score (CS) on the diagnostic accuracy of MDCT. Our aim was to assess the agreement of MDCT and ICA and to evaluate the influence of CS on this agreement. Methods: We enrolled 266 consecutive patients who underwent evaluation with 64-slice MDCT and ICA. Standard CS software tools were used to calculate the Agatston score. Stenosis was qualitatively classified as mild, moderate, or severe by 1 blinded observer and the results were compared with those of ICA, which was used as the gold standard. Results: The mean age of the patients was 65.4 11.2 years, and 188 patients (70.3%) were men. A total of 484 segments with coronary stenosis mild were qualitatively evaluated and quantified with MDCT. Noninvasive measurements were concordant with ICA in 402 stenoses (83.05%; Kappa, 0.684), with no significant differences between vessels and with no statistically significant influence of CS on this agreement (OR, 0.93; 95%CI, 0.76-1.09; P = .21). Multidetector computed tomography had high sensitivity, specificity, positive predictive value, and negative predictive value on a per-segment, per-vessel, and per-patient basis. Conclusions: Non-ICA using MDCT showed good agreement with ICA in the qualitative quantification coronary stenosis and CS had no significant impact on this agreement (AU)

Gliomatosis cerebri is a diffuse infiltrating glioma of neuroepithelial origin that affects more than 2 cerebral lobes. This is rarely seen in pediatric patients. The clinical presentation and imaging are very unspecific, and a biopsy is typically needed for the diagnosis. Given the widespread nature of the disease, surgical treatment is not possible and has a poor overall prognosis. A pediatric patient presented with elevated intracranial pressure. All initial studies were negative, and the imaging showed a symmetrical affection involving the supratentorial and infratentorial regions. A biopsy ultimately confirmed gliomatosis cerebri. This case describes a unique clinical presentation of gliomatosis cerebri in a pediatric patient.

BACKGROUND: Although several hypotheses have been proposed, the true origin and pathogenesis of aortic intramural hematoma (IMH) remain unclear. Evolution of patients with aortic IMH is highly variable. Progression to classic aortic dissection, aneurysm or to complete resolution have been described. Our purpose was to assess in-hospital and mid-term evolution of patients with aortic IMH. METHODS: From 2000 to 2015, 40 patients with aortic IMH were prospectively and consecutively recruited in a tertiary care referral center. Aortic IMH was defined as the presence of a circular or crescent-shaped thickening of the aortic wall (≥5mm) in the absence of detectable blood flow inside, within the context of acute aortic syndrome. RESULTS: Twenty three patients (57.5%) had type A, and 17 (42.5%) type B IMH. Up to 34.7% of patients with type A and 47.1% with type B IMH showed intimal tears in the imaging test at admission. In-hospital mortality was higher in the type A IMH group. All-cause mortality after discharge was 20%, without significant differences among groups. Out of hospital death was related to the aortic pathology in just one patient. At follow-up, radiological persistence of IMH was observed in 35.7% of patients with type A and 60% of those with type B IMH. CONCLUSIONS: IMH related mortality takes place primarily during the acute phase of the disease. Clinical evolution after discharge is favorable, either in cases of reabsorption or persistence of the IMH. Imaging test findings rekindle the debate on the true training mechanism of the aortic IMH.

OBJECTIVES: To demonstrate non-inferiority of iobitridol 350 for coronary CT angiography (CTA) compared to higher iodine content contrast media regarding rate of patients evaluable for the presence of coronary artery stenoses. METHODS: In this multicentre trial, 452 patients were randomized to receive iobitridol 350, iopromide 370 or iomeprol 400 and underwent coronary CTA using CT systems with 64-detector rows or more. Two core lab readers assessed 18 coronary segments per patient regarding image quality (score 0 = non diagnostic to 4 = excellent quality), vascular attenuation, signal and contrast to noise ratio (SNR, CNR). Patients were considered evaluable if no segment had a score of 0. RESULTS: Per-patient, the rate of fully evaluable CT scans was 92.1, 95.4 and 94.6 % for iobitridol, iopromide and iomeprol, respectively. Non-inferiority of iobitridol over the best comparator was demonstrated with a 95 % CI of the difference of [-8.8 to 2.1], with a pre-specified non-inferiority margin of -10 %. Although average attenuation increased with higher iodine concentrations, average SNR and CNR did not differ between groups. CONCLUSIONS: With current CT technology, iobitridol 350 mg iodine/ml is not inferior to contrast media with higher iodine concentrations in terms of image quality for coronary stenosis assessment. KEY POINTS: ⢠Iodine concentration is an important parameter for image quality in coronary CTA. ⢠Contrast enhancement must be balanced against the amount of iodine injected. ⢠Iobitridol 350 is non-inferior compared to CM with higher iodine concentrations. ⢠Higher attenuation with higher iodine concentrations, but no SNR or CNR differences.

When pertussis is associated with hyperleukocytosis, mortality approaches to 80%. Immature leukocytes have been identified in pulmonary arterioles, small arteries and venules. Techniques aimed at reducing leukocyte mass might improve the prognosis of these patients. We report our experience with 3 patients in whom a leukoreduction was performed in the context of severe pertussis and hyperleukocytosis.

OBJECTIVE: The aim of this study was to evaluate the use of procalcitonin (PCT) and C-reactive protein (CRP) on admission as predictors of the severity of appendicitis in children. METHODS: We prospectively studied 111 consecutive patients admitted with a diagnosis of acute appendicitis between July 2009 and February 2010 and recorded the following variables: age, sex, time since diagnosis, laboratory data, complications (abscess, intestinal obstruction), presence of hemodynamic instability, mortality, length of stay, and need for admission to the pediatric intensive care unit. Patients were divided into 2 groups according to the diagnosis confirmed during surgery (group 1, appendicitis; group 2, localized or generalized peritonitis). RESULTS: Group 1 comprised 69 patients, and group 2 comprised 42 patients. Procalcitonin and CRP values were significantly lower in group 1 than in group 2 (0.15 vs 4.95 ng/mL [P < 0.001] and 3 vs 14.3 mg/dL [P < 0.001]). For a diagnosis of peritonitis, a PCT cutoff of 0.18 ng/mL gave a sensitivity of 97%, specificity of 80%, positive predictive value of 72%, and negative predictive value of 89.3%. The equivalent values for a CRP cutoff of 3 mg/dL were 95%, 74%, 68%, and 96.2%. Complications and the need for admission to the pediatric intensive care unit were more common in patients with peritonitis. CONCLUSIONS: On admission, CRP and PCT predict the outcome of pediatric patients with appendicitis. Children with CRP greater than 3 mg/dL and/or PCT greater than 0.18 ng/mL have a greater risk of complications; thus, intervention should be early, and patients should be monitored closely.

BACKGROUND: Pleuropulmonary blastoma (PPB) is the most common lung neoplasms in childhood. Usually presents as recurrent respiratory infections and in some cases as pneumothorax. CASE REPORT: We report the case of a 2-year-old patient that was diagnosed with PPB, that first manifested as recurrent pneumothorax. Three chest computed tomography were necessary for the diagnosis. The first 2 tomographies showed no abnormalities suggestive of malignancy. The patient had a family history of both PPB and leukemia. Three years and a half after completion of treatment, the patient is in complete remission. CONCLUSIONS: PPB is an uncommon disease but is the most common pulmonary neoplasms in childhood. We must suspect it in patients with a suggestive family history and recurrent pneumothorax in the same location.

Cystic adenomatoid malformation of the lung is a rare malformation of the lung airway which often performed diagnosed in the prenatal period by ultrasound. Ultrasound monitoring should be performed during pregnancy to assess lung development. We report the case of a 4-year-old patient with prenatal diagnosis of cystic adenomatoid malformation of the lung, not confirmed by chest radiograph at birth. The patient underwent surgery at 4 years of age after diagnosis was made for presenting recurrent pneumonia. A normal chest radiograph at birth does not exclude this malformation and a computerized tomography at 4 weeks of birth must be done to confirm or rule out this anomaly. Once the diagnosis is made, surgical treatment should be prompted to avoid complications.

La malformación adenomatoidea quística pulmonar (MAQP)es una anomalía de la vía aérea pulmonar poco frecuente cuyodiagnóstico suele realizarse en el período prenatal medianteecografía. Durante el embarazo, debe realizarse seguimiento ecográfico para valorar el desarrollo pulmonar. Presentamos el caso clínico de una paciente de 4 años con diagnóstico prenatal de MAQP, no confirmado mediante radiografía de tóraxrealizada al nacimiento, lo cual retrasó el diagnóstico definitivo; fue intervenida con 4 años de edad tras haber presentado varias neumonías a repetición. Una radiografía de tórax normal realizada al nacimiento no descarta la presencia de estamalformación, por lo que es necesario realizar una tomografía computarizada a las 4 semanas del nacimiento para confirmar o descartar la MAQP. Una vez diagnosticada, el tratamiento quirúrgico debe ser precoz para evitar complicaciones.(AU)
