Introduction. Intravenous leiomyomatosis with cardiac extension is an extremely rare uterine tumor. We report here a case of intravenous leiomyoma extending to the right atrium, diagnosed in a patient having leiomyoma. Case Presentation. A 39-year-old woman with no symptoms and a past medical history of two myomectomy operations (7 and 3 years previously) was admitted to our clinic for routine ...

Fetal cardiac tumors are rare conditions and their incidence ranges from 0.08% to 0.2%[1]. However, this percentage during fetal life may be underestimated, given that regression commonly occurs. It should also be noted that atrial tumors may be small or, when located in the septum or ventricular cavity, often mimic an echogenic focus (golf ball sign), thus leading to difficulty in recognizing ...

PURPOSE To prospectively evaluate whether cardiac gating can improve the reproducibility of intravoxel incoherent motion (IVIM) parameters in the head and neck, we performed IVIM diffusion-weighted imaging (DWI) using 4 b values (4b), 4 b values with cardiac gating (4b gating) and 17 b values (17b). METHODS We performed IVIM DWI twice per person on nine healthy volunteers using 4b, 4b gating ...

A left atrial mass associated with coronary artery disease is often diagnosed as a mural thrombus rather than other possible etiologies such as benign primary cardiac tumor (myxoma, lipoma), a malignant primary cardiac tumor (sarcoma, lymphoma), or secondary involvement for extracardiac tumors. Malignant lymphoma initially presenting as intracardiac masses is very rare. Chest computed tomograph...

t-wave oversensing occurs when the counter starts giving dual beeps for every cardiac cycle instead of one. this usually happens when the monitoring lead displays a tall t wave, which is also sharp. r wave sensing algorithms of the devices do not sense t wave because the slow rate of the t wave is much less than that of the r wave. but the slow rate of t waves may change with time and also beca...

We report a case of a 33-year-old woman with emergency admission due to dyspnoea and fever. History included squamous cell carcinoma of the cervix in complete remission. Contrast-enhanced computed tomography (CT) scanning of the chest, which was indicated to rule out pneumonia, revealed an infiltrative cardiac mass. Further assessment of the tumour by echocardiography and cardiac magnetic reson...

We present in this paper a local force model and its integration to a hierarchical analysis in the estimation of the left ventricle motion over a cardiac cycle. The local force model is derived from the dynamics of independent point masses driven by local constant forces over a short time period. A force eld is assumed to remain constant over short periods of time driving independent point mass...
