AbstractPurposeMyocardial contusion can be a life-threatening condition in patients who sustained blunt thoracic trauma. The diagnostic approach remains a subject of debate. The aim of this study was to determine the sensitivity and specificity of echocardiography, electrocardiography, troponins T and I (TnT and TnI), and creatine kinase muscle/brain (CK-MB) for identifying patients with a myocardial contusion following blunt thoracic trauma.MethodsSensitivity and specificity were first determined in a 10-year retrospective cohort study and second by a systematic literature review with meta-analysis.ResultsOf the 117 patie...

ConclusionSternal wire complications secondary to migration beyond the sternum are rare but potentially fatal. Precise wire location and risk assessment with CT are more appropriate when wire location cannot be clearly delineated by plain film radiography.

Authors: Alderwish E, Schultz E, Kassam Z, Poon M, Coplan N Abstract There is a broad differential diagnosis for patients presenting with acute chest pain. History, physical examination, electrocardiogram, and serial troponin assays are pivotal in assessing patients with suspected acute coronary syndrome. However, if the initial workup is equivocal, physicians are faced with a challenge to find the optimal strategy for further triage. Risk stratification scores have been validated for patients with known acute coronary syndrome, such as the TIMI and GRACE scores, but there may be limitations in undifferentiated che...

Objective To evaluate image quality and radiation dose exposure of low-kV setting and low-volume contrast medium (CM) computed tomography angiography (CTA) protocol for transcatheter aortic valve implantation (TAVI) planning in comparison with standard CTA protocol. Methods Sixty-patients were examined with 256-row MDCT for TAVI planning: 32 patients (study group) were evaluated using 80-kV electrocardiogram-gated protocol with 60 mL of CM and IMR reconstruction; 28 patients underwent a standard electrocardiogram-gated CTA study (100 kV; 80 mL of CM; iDose4 reconstruction). Subjective and objective image quality was e...

ConclusionsClinicians may consider deferring immediate cardiac catheterization and attribute electrocardiogram changes to acute pancreatitis in patients presenting with angina pectoris and acute pancreatitis if confirmed by normal cardiac enzymes and elevated levels of lipase and amylase. However, when clinical signs and electrocardiogram findings are highly suggestive of myocardial ischemia/injury, immediate noninvasive coronary computed tomography angiography may be the best approach to make an early diagnosis.

Abstract Clinical data: Infant, 7 months, female, referred to our department at one month of age, suspecting of congenital heart disease for further investigation. Chest radiography: Demonstrates cardiomegaly and prominent pulmonary vascular markings. Electrocardiography: Shows right ventricular hypertrophy and left anterior fascicular block. Echocardiography: Evidenced common atrioventricular valve with two orifices and the left superior pulmonary vein draining on the brachiocephalic vein. Computed tomography angiography: This complementary imaging exam was performed to confirm the diagnosis. Diagnosis: The patient presen...

Rationale: Although implantation of Amplatzer membranous ventricular septal defect occluder (AVSDO) is an alternation to surgical treatment, the interventional therapy is disapproved by FDA due to high incidence of complete atrioventricular block (cAVB) post closure during early and middle term follow-up. However, long-term outcomes of the accumulating numbers of patients who had received AVSDO in the past decades, still remain an issue of concern and late occurrence of potentially catastrophic heart block long after hospital discharge is especially worrying, but rarely documented. We firstly reported a pediatric case wi...

ConclusionsCardiac substructure delineation using E-CTA was feasible and inclusion in optimization led to modest improvements in sparing of radiosensitive cardiac substructures for some patients.
