Evaluation of non-ECG and ECG-gated computed tomographic angiography for three-dimensional printing of anomalous coronary arteries in dogs with pulmonic stenosis

ConclusionIn dogs, CTA is effective for diagnosis of coronary artery anomalies. Printed 3D models of ECG-gated studies were of excellent quality and allowed direct visualization of abnormal coronary artery anatomy. The usefulness of these models to improve the understanding of anomalous coronary artery anatomy could be evaluated in future studies.

AbstractPremature ventricular complexes (PVCs) are common arrhythmias in the clinical setting. PVCs in the structurally normal heart are usually benign, but in the presence of structural heart disease (SHD), they may indicate increased risk of sudden death. High PVC burden may induce cardiomyopathy and left ventricular (LV) dysfunction or worsen underlying cardiomyopathy. Sometimes PVCs may be a marker of underlying pathophysiologic process such as myocarditis. Identification of PVC burden is important, since cardiomyopathy and LV dysfunction can reverse after catheter ablation or pharmacological suppression. This state-of...

This is a previously healthy male teenager who was awoken by chest pain.  He was seen at another hospital and found to have a slightly elevated troponin, then underwent a CT pulmonary angiogram (PE) protocol which revealed a right sided pneumonia.  He was treated with Ceftriaxone and azithromycin.p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Calibri; background-color: #fefefe}The pain is described as located in the midsternal area, radiating to the right arm, described as 8-9/10 and worse with deep inspirations.  He endorsed cough, fever, and body aches in the previous day...

We read with great interest the article by Lindgren and colleagues,1 who found that no gender differences in electrocardiograph (ECG) findings indicating an early coronary angiography (CAG) in patients with out-of-hospital cardiac arrest (OHCA). Though this study sounds scientific, some critical issues should be discussed.

A 38 year-old obese man who is currently smoking was referred to our hospital with chest pain. His electrocardiography and echocardiography suggested myocardial infarction in proximal region of left coronary artery. Emergent coronary angiography revealed 99% stenosis at mid portion of LAD and diffu...

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...

A 40-something suffered witnessed ventricular fibrillation, had bystander CPR, but could not be defibrillated after 4 attempts.He was transferred to the ED and put on extracorporeal life support (ECLS, ECMO).A series of ED Transesophageal echos (TEE) was done over 23 minutes before an ECG was recorded.  We usually do not get ROSC before angiography in these cases, and recording the ECG is not as important as usual, because we send them all to the cath lab by our ECMO protocol.This is before another defibrillation attempt, during chest compressions:Orientation:The probe is in the esophagus, right next to the left ...

ConclusionAMI as a result of penetrating trauma is rare, but can occur secondary to an acute thrombus, even in the absence of a direct cardiac injury. MI should be a consideration in patients with penetrating trauma to the chest, regardless of the intensity of the trauma. At minimum, a 12-lead electrocardiogram (ECG) and a baseline troponin should be obtained at initial evaluation and post-operatively, if surgically managed. If ECG demonstrates findings concerning for MI, it should be followed with an echocardiogram and/or cardiac angiogram to further help guide management, with an early cardiology consultation.
