Current advanced technology allows the accurate three-dimensional reconstruction of cardiac structures using multiple images from two-dimensional intracardiac echocardiography (ICE). This technology is applicable to atrial fibrillation (AF) ablation and provides real-time anatomical information on relevant atrial structures and myocardial thickness as well as suitable sites for transseptal punc...

Use of normothermic venous inflow occlusion enabled removal of an intracardiac tumor in a 4 yr old, 27 kg, spayed female Airedale terrier with a history of appendicular osteosarcoma and recent exertional syncope. Inflow venous occlusion via a median sternotomy thoracotomy without hypothermia was used to access the mineralized mass within the right ventricular outflow tract. Duration of circulat...

We prospectively analyzed the learning process for transseptal catheterization guided by intracardiac echocardiography, in 50 patients who underwent radiofrequency ablation for left atrial arrhythmias. In 20 patients the intracardiac echocardiography catheter was positioned in the right atrium to visualize the fossa ovalis and the tenting of the fossa caused by the Brockenbrough needle. In the ...

We recently combined noncontact mapping and intracardiac echocardiography (ICE) in a single cathetersystem that permitted detailed, single-beat, 3-D electricalanatomical imaging of the heart. In the present study we developed a nonfluoroscopic electrode-catheter localization method and integrated it with noncontact electrical-anatomical imaging. The difference in nonfluoroscopic electrode locat...

Two-dimensional echocardiography has become the diagnostic method of choice for identifying intracardiac masses. However, adjacent extracardiac structures may closely mimic intracardiac masses on the two-dimensional echocardiogram. Five cases of a previously unrecognized phenomenon in which a diaphragmatic hernia mimicked an intraatrial mass are reported. Techniques to identify a diaphragmatic ...

The authors describe a 51-year-old man with chronic lymphocytic leukemia who presented with respiratory distress and then died suddenly while in hospital. Autopsy revealed pulmonary leukostasis and a large intracardiac mass containing mostly mature lymphocytes and fibrin. Although leukostasis and lymphocyte thrombi have been described (albeit rarely) in chronic lymphocytic leukemia, an intracar...

Thromboembolism is a rare complication of primary nephortic syndrome. Both venous and arterial thrombosis might occur in steroid responsive and steroid resistant nephrotic syndrome. This is the report of an infant with nephrotic syndrome and renovascular hypertension, complicated with asymptomatic intracardiac thrombus and managed appropriately with medical treatment.
