The "swinging" heart. A pericardial effusion is an abnormal accumulation of fluid in the pericardial cavity. The pericardium is a two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane. The two layers of the serous membrane enclose the pericardial cavity (the potential space ...
Pericarditis is inflammation of the pericardium, the fibrous sac surrounding the heart. [ 8 ] Symptoms typically include sudden onset of sharp chest pain, which may also be felt in the shoulders, neck, or back. [ 1 ] The pain is typically less severe when sitting up and more severe when lying down or breathing deeply. [ 1 ]
Cardiac asthma is the medical condition of intermittent wheezing, coughing, and shortness of breath that is associated with underlying congestive heart failure (CHF). [1] Symptoms of cardiac asthma are related to the heart's inability to effectively and efficiently pump blood in a CHF patient. [2] This can lead to accumulation of fluid in and ...
Pericardial fluid. A transverse section of the thorax, showing the contents of the middle and the posterior mediastinum. The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart. Pericardial fluid is the serous fluid secreted by the serous layer ...
Especially when accompanied by shortness of breath, these symptoms can indicate cardiac amyloidosis, Zoghbi says. “It’s a problem of protein misfolding,” he explains. “The protein, which ...
The practice of intracardiac injection originated in the 1800s. It was commonly performed during the 1960s, as it was considered the fastest way to get medication to the heart. The practice began declining during the 1970s as more reliable delivery methods (i.e., intravenous, endotracheal, and intraosseous) came into use. Around that time ...
Cardiac tamponade, also known as pericardial tamponade (/ ˌtæm.pəˈneɪd / [ 4 ]), is a compression of the heart due to pericardial effusion (the build-up of pericardial fluid in the sac around the heart). [ 2 ] Onset may be rapid or gradual. [ 2 ] Symptoms typically include those of obstructive shock including shortness of breath, weakness ...
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing (dyspnea), leg or feet swelling, and fatigue. [ 1 ] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs ...
