Papillary fibroelastomas are cardiac benign tumours. Among the benign cardiac tumor, papillary fibroelastomas are reported second after myxomas. Most often diagnosed incidentally, papillary fibroelastomas may embolize to cerebral circulation. Valvular locations are predominant; location in left atrium is rare. In this paper, we present a case of papillary fibroelastoma located in left atrium wi...

But he gave no distinctive report of carotid strokes. Giovanni Battista Morgagni (1682–1771) in his De Sedibus (1761) showed extravasation of blood caused damage and laceration to the brain and cavities resulting in apoplexy [8] . Morgagni recognised the cerebral lesion as causing contralateral palsy. This was the first clear account of cerebral haemorrhage causing apoplectic stroke in distinct...

Bubbles introduced to the arterial circulation during invasive medical procedures can have devastating consequences for brain function but their effects are currently difficult to quantify. Here we present a Monte Carlo simulation investigating the impact of gas bubbles on cerebral blood flow. For the first time, this model includes realistic adhesion forces, bubble deformation, fluid dynamical...

Transcatheter aortic valve replacement (TAVR) has become a first-line treatment for severe stenosis with intermediate to high-risk population its use increasingly expanding into younger and low-risk cohorts as well. Cerebrovascular events are one of the most serious consequential complications TAVR, which increase morbidity mortality. The probable origin such neurological is embolic in nature m...

Myxomas, the most common primary cardiac tumors, are known as a source of cardiogenic emboli. The possibility of their early detection has made them of great importance for emergency medicines. Detection of the disease is probable at early stages using echocardiography and associate complications such as syncope, cerebral embolic ischemic strokes, and sudden death. We report experience of a rar...

Objective: Coronavirus-2019 (Covid-19) was first observed in December 2019 and recognized as a pandemic by the World Health Organization. Apart from respiratory symptoms, neurological, dermatological, gastrointestinal symptoms can also occur humans. Some neurological may be caused microembolism. The present study aims to determine presence of microemboli patients with Covid-19 using Transcrania...

Many bubbles that enter the brain circulation pass through the arterioles and capillary beds and do not obstruct blood flow. Nevertheless, such bubbles could still disrupt brain function. An open-brain model in five anesthetized rabbits used the minimum dose of air (25 microliters) necessary to cause embolism of the exposed vessels, and these bubbles passed through the vessels without any trapp...
