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 .
Purulent Pericarditis; Echocardiogram showing pericardial effusion with signs of cardiac tamponade: Specialty: Cardiology: Symptoms: substernal chest pain (exacerbated supine and with breathing deeply), dyspnea, fever, rigors/chills, and cardiorespiratory signs (i.e., tachycardia, friction rub, pulsus paradoxus, pericardial effusion, cardiac tamponade, pleural effusion)
The disease consists of persistent low-grade fever, chest pain (usually pleuritic), pericarditis (usually evidenced by a pericardial friction rub, chest pain worsening when recumbent, and diffuse ST elevation with PR segment depression), and/or pericardial effusion. The symptoms tend to occur 2–3 weeks after myocardial infarction but can also ...
The pericardial rub is said to be generated from the friction generated by the two inflamed layers of the pericardium; however, even a large pericardial effusion does not necessarily present a rub. The rub is best heard during the maximal movement of the heart within the pericardial sac, namely, during atrial systole , ventricular systole, and ...
The differential diagnoses of Kussmaul's sign includes constrictive pericarditis, restrictive cardiomyopathy, pericardial effusion, and severe right-sided heart failure. [ citation needed ] With cardiac tamponade , jugular veins are distended and typically show a prominent x descent and an absent y descent as opposed to patients with ...
On a chest X-ray, the normal heart silhouette should have a clear and defined outline. However, in cases of pericardial effusion, the accumulation of fluid within the pericardial sac causes the heart to appear enlarged and assumes a shape that is reminiscent of a water bottle, with relatively smooth cardiac contours. [2]
Pulsus paradoxus is a sign that is indicative of several conditions, most commonly pericardial effusion. [ 1 ] The paradox in pulsus paradoxus is that, on physical examination , one can detect beats on cardiac auscultation during inspiration that cannot be palpated at the radial pulse . [ 1 ]
This places the heart in proximity to the chest wall for easier insertion of the needle into the pericardial sac. [5] [7] For patients that are awake, a local anaesthetic is applied. [8] A large needle is inserted through the skin of the chest into the pericardium, and the practitioner aspirates the pericardial effusion into a syringe. [6]
