چکیده

Endocardial lesions are caused not only by inflammatory processes but also by myocardial ischemia, resulting in endocardial thrombosis and cerebral embolism. We deviced a method for direct visualization of endocardial damages by a novel dye image cardioscopy with Evans blue and examined its feasibility in patients with heart disease. The dye was injected into the left ventricle before and after endomyocardial biopsy. Endocardial surface was stained in dark blue in 63% of patients with angina pectoris before biopsy. After biopsy, the biopsied portions were stained in blue in all. The results indicate that endocardium is damaged even in apparently intact LV in patients with ischemic heart disease and that endomyocardial biopsy causes severe endocardial damages.

Recent Advances in Percutaneous Cardioscopy

Percutaneous cardioscopy, using high-resolution fiberoptic imaging, enables direct visualization of the cardiac interior, thereby enabling macroscopic pathological diagnosis. Percutaneous cardioscopy has demonstrated that the endocardial surface exhibits various colors characteristic of different heart diseases. This imaging modality can now be used for evaluation of the severity of myocardial ...

Percutaneous fiberoptic cardioscopy of the left ventricle.

The feasibility of percutaneous transluminal cardioscopy of the left ventricle was examined in 35 patients with or without various heart diseases. A guiding balloon catheter (7 or 9 French) was introduced through the right femoral artery into the left ventricle. The balloon was inflated, and a fiberscope (1.6 or 4.3 French) was advanced to the distal tip of the catheter. The balloon was then ma...

A Novel Method for Skin Lesion Segmentation

Skin cancer has been the most usual and illustrates 50% of all new cancers detected each year. If they detected at an early stage, treatment can become simple and economically. Accurate skin lesion segmentation is important in automated early skin cancer detection and diagnosis systems. The aim of this study is to provide an effective approach to detect the skin lesion border on a purposed imag...

PERCUTANEOUS TRANSTHORACIC BIOPSY USING TRU-CUT NEEDLE

Biopsies of thoracic lesions guidance. 22 of the 1 12 lesions were mediastinal and 83 were pleuroparenchymal. A large-bore 14-gauge Tru-cut needle was used in all patients. Adequate specimens for histologic examination were obtained in 98%. The overall accuracy was 91 % with 9% false negative and no false positive diagnoses. Despite the large size of the needle, the total number of complic...
