Characteristic findings of acute spontaneous coronary artery dissection by cardiac computed tomography

Conclusion: CCT was able to identify the presence of SCAD in most of the patients in the acute phase of this elusive and challenging clinical entity. In addition, in this setting, CCT revealed unique and distinct radiologic features and provided a precise assessment of lesion severity.

AbstractPurpose of ReviewThe most pertinent clinical question in post-coronary computed tomography angiography (CCTA) patients is the assessment of the physiological significance of an anatomically identified stenosis. The clinical application of radionuclide MPI using single-photon emission computed tomography (SPECT) versus positron emission tomography (PET) in the evaluation and management of patients with an inconclusive CCTA is reviewed using a case-based approach.Recent FindingsRecent evidence suggests that CCTA is the most sensitive non-invasive test to exclude angiographic CAD and may be an effective first-line tes...

ConclusionsConventionally described anatomy was only seen on the left side in 70.6% and 69.4% on the right side of subjects. Single renal arteries are seen in 54.4% showing that conventional anatomy has a relatively low incidence.

Authors: Saraste A, Knuuti J Abstract The European Society of Cardiology (ESC) has recently published new guidelines on the diagnosis and management of chronic coronary syndromes (CCS). Due to variable symptoms, objective tests are often necessary to confirm the diagnosis, exclude alternative diagnoses, and assess the severity of underlying disease. This review provides a summary of the main diagnostic strategies listed in the guidelines for evaluation of patients suspected of having obstructive coronary artery disease (CAD). Based on data from contemporary cohorts of patients referred for diagnostic testing, ...

METHODS: A total of 533 patients who received a Sapien XT or Sapien 3 ...

ConclusionTooth loss was independently associated with CAB and predicted a poorer functional outcome among IS and TIA patients.Clinical relevanceClinical assessment of tooth loss may provide important information on risk for CAB and poorer functional outcome among stroke patients.

In a recent Vascular Images section of the Journal, a case involving a “symptomatic extracranial carotid artery aneurysm” was presented.1 Three-dimensional computed tomography angiography showed a 1.9- × 1.4-cm aneurysm within a tonsillar loop of the mid to distal internal carotid artery. Notwithstanding the fact that I am not entirely certain how this lesion mig ht have been responsible for the patient's ocular migraines or dizziness, it is understandable that the discovery of such a lesion might arouse concern.

A 7.5-cm mass at the upper pole of the right kidney (Fig 1) was incidentally discovered in a 48-year-old woman and was believed to represent a renal angiomyolipoma. On the pre-embolization computed tomography (CT) angiogram, a bilateral adrenal-renal fusion (i.e., anomalous, incomplete encapsulation of the adrenal gland and kidney during embryogenesis) was noted. On coronal images (Fig 2), the mass appeared to arise from the kidney, but sagittal images (Fig 3) suggested an adrenal origin. Angiography demonstrated that the mass was supplied by branches of the superior suprarenal artery (Fig 4), confirming the diagnosis of a...

Conclusions: Dysphagia lusoria is an impairment of swallowing due to compression from an aberrant right subclavian artery. The diagnosis is always difficult, as the symptoms are often nonspecific. It is imperative to accurately identify and properly manage dysphagia in pediatric age and this is only possible with an anamnestic, clinical and instrumental process that takes into account an adequate differential diagnosis.

AbstractThe pseudoaneurysm (PA) is a perfused sac directly connecting with the arterial lumen by an interruption of the vessel wall continuity, more commonly secondary to trauma or iatrogenic causes. Aim of our study was to determine the accuracy and usefulness of Doppler techniques in the diagnosis of peripheral iatrogenic PAs secondary to minimally invasive procedures. From a three year prospective research, 20 Duplex Ultrasound (DUS) studies in as many patients presenting with periarterial pulsating mass clinically suspected for PA secondary to minimally invasive procedures were selected. The PA final diagnosis was conf...

Abstract: A healthy 56-year-old man presented with vision changes and left upper extremity motor and sensory changes. MRI of the brain without contrast was significant for multifocal areas of restricted diffusion in multiple vascular territories. Neuro-Ophthalmic evaluation revealed an inferonasal visual field defect in the left eye, thickened choroid on optical coherence tomography, and bilateral delayed arteriovenous and choroidal filling on fluorescein angiogram. Repeat MRI demonstrated interval enlargement of many of the same foci of abnormal diffusion-weighted imaging signal. Computed tomography of the abdomen and p...
