A rare case of a Wilms tumor with intracardiac neoplastic extension is presented. The good prognosis of even extensive nephroblastoma is the reason for attempting a radical surgical approach to patients with intracardiac tumor thrombus. The exact preoperative delineation of the intracasal tumor extension is essential for a safe and successful operation. Ultrasonography in combination with echoc...

Even though intracardiac sarcoma metastases are rare, they have been previously reported in the literature. We report the case of a 60-year-old man who had a synovial sarcoma with metastasis in the right ventricle. These findings were associated with the presence of a new cardiac murmur and severe thrombocytopenia. The treatment with systemic chemotherapy resulted in a normalization of the pati...

Intracardiac blood cysts are thin-walled congenital cysts located in the endocardium and are seen predominantly in infants. They are rare in adults and are typically asymptomatic. However, complications such as valve dysfunction and left ventricular outflow tract obstruction have been reported in adults. We report a 42-year-old woman who developed an embolic stroke in association with intracard...

A cohort of 61 consecutive patients 24 months of age of younger had palliative shunts for symptoms of tetralogy of Fallot during a 12-year period. Thirty-six of these patients have been followed through definitive intracardiac repair or to death. For analysis palliative operations were separated into two six-year periods, 1965--1970. During the first period seven of 30 infants operated on died;...

The locations, projections, and functions of the intracardiac ganglia are incompletely understood. Immunocytochemical labeling with the general neuronal marker protein gene product 9.5 (PGP 9.5) was used to determine the distribution of intracardiac neurons throughout the cat atria and ventricles. Fluorescence microscopy was used to determine the number of neurons within these ganglia. There ar...

BACKGROUND Radiofrequency catheter ablation requires precise positioning of the ablation electrode. Fluoroscopically guided catheter manipulation has limitations, and there are risks of radiation exposure. The purpose of this study was to examine the feasibility of guiding catheter ablation within the right atrium with catheter-based intracardiac echocardiography. METHODS AND RESULTS A 10F, 1...

BACKGROUND Recently, intracardiac echocardiography emerged as a useful tool in the electrophysiology laboratories for guiding transseptal left heart catheterizations, for avoiding thromboembolic and mechanical complications and assessing the ablation lesions characteristics. Although the value of ICE is well known, it is not a universal tool for achieving uncomplicated access to the left atrium...
