The primary fibrosarcoma of the heart is a rare tumor. There are no exact numbers about its incidence, but even among malignant cardiac tumors, only around 3% are fibrosarcomata. Symptoms are nonspecific with signs of right or left heart failure depending on localization. Diagnosis is thereby...
Background Subthreshold electrical stimulation of the left stellate ganglion (LSG) can induce nerve sprouting and sympathetic hyperinnervation in canine ventricles. It is unclear whether a similar neural plasticity involving both sympathetic and parasympathetic innervation also exists in the atria.
A 77-year-old female initially presented with symptomatic mitral valve stenosis involving a bioprosthesis that had been implanted 8 months earlier for myxomatous mitral valve disease and severe valvular regurgitation. The patient was taken for a second mitral valve replacement due to stenosis....
Background It is not known whether overexpansion modifies stent recoil, symmetric distribution of struts, and neointimal hyperplasia.
Background Cardioversion (CV) success of atrial fibrillation (AF) inversely correlates to the size of the left atrium (LA). Atrial fibrillation and its most important risk factor, congestive heart failure (CHF), both induce atrial structural enlargement and fibrosis. To investigate the effect of...
A large pericardial mass, which was found to be a perivascular epithelioid cell tumor, was excised from a 20-year-old man. To our knowledge, this is the first report of this distinctive neoplasm as a pericardial mass.
Coronary artery aneurysms, commonly atherosclerotic, are usually asymptomatic and can be diagnosed incidentally during investigation for ischemic heart disease or on autopsy. An asymptomatic giant right coronary artery aneurysm presenting as a paracardiac mass discovered on autopsy is reported...
The adhesion of the monocytes to the endothelium and their extravasation into the intima are key steps in atherogenesis. Studies showed the essential role of L-selectin (CD62-L), expressed by the monocytes, and the platelets by forming complexes with monocytes. The delipided apolipoprotein (Apo)...
