We describe an 81-year-old woman with an episode of loss of consciousness and a mass inside the left atrium. We demonstrate the added value of three-dimensional transoesophageal echocardiography in the differential diagnosis of the cardiac masses.

Cardiac calcified amorphous tumors (CATs) can arise in all four chambers of the heart. Cardiac CATs can cause diverse symptoms according to their locations, and mass or embolic effects. Pulmonary emboli arising from cardiac CATs have been reported, but the true incidence is unknown due to their rarity. Herein we report a rare case with diffuse CATs in the right ventricle which caused a calcific...

The author has presented an excellent paper describing considerations that went into the development and imple­ mentation of the subject facility. The use of some pho­ tographs in the paper was particularly helpful. The photo on p. 240 shows open structural members around the bottom of the key air pollution control elements. For very little additional capital cost, these areas can be en­ closed...

Primary cardiac tumors are very rare, papillary fibroelastoma (PFE) being the second most common benign tumor of the heart in previous series. However, as a consequence of increased imaging examinations, incidental PFE may represent the most common cardiac tumor. Their clinical presentation varies from incidental asymptomatic masses to severe life-threatening cardiovascular complications necess...

Nurse staffing and scheduling is a major health human resource issue currently facing healthcare organizations. To increase the capacity of healthcare organizations to address a variety of issues related to nurse staffing and scheduling, a mult-isite collaborative project was undertaken. The primary focus of this project was

Motivated by the GKM picture of the equivariant cohomol-ogy ring for a torus action on an orbifold we define one-skeletons and their corresponding rings, H(Γ, α). We prove that, under a mild gener-icity condition, such a ring is a free S(g *)−module, with generators given by Thom classes of flow-outs of the vertices. We also show that many interesting notions and results in symplectic geometry,...

Background: Ovarian cancer is the fifth most common cancer in woman and the fifth most frequent cause of cancer death. Ovarian cancers are usually asymptomatic until metastasized, patients have advanced disease at diagnosis in more than 2/3 of the cases. Totally 75-80 % of ovarian masses are benign. The strongest patient related risk factor for ovarian cancer is increasing age. The most ovarian...

Abstract Background Cardiac masses (CMs) are a diagnostic dilemma in clinical practice and require multimodality imaging to assess malignancy, which is essential guide the proper treatment. Aim To define accuracy agreement between echocardiographic features second-level techniques (cardiac computed tomography – CCT or cardiac magnetic resonance CMR) patients with CMs. Methods All consecutive hi...
