pericardiacophrenic veins |
The veins accompanying the pericardiacophrenic artery and emptying into the brachiocephalic veins or superior vena cava. Synonym: venae pericardiacophrenicae. (05 Mar 2000) |

pericardial |
<anatomy> Of or pertaining to pericardium; situated around the heart. <physiology> Pericardial fluid, a serous fluid of a pale yellow colour contained in the pericardium. Source: Websters Dictionary (01 Mar 1998) |
pericardial branch of phrenic nerve |
<anatomy, nerve> One of the branches of phrenic nerve distributed to the pericardium and adjacent mediastial parietal pleura. Synonym: ramus pericardiacus nervi phrenici. (05 Mar 2000) |
pericardial branch of thoracic aorta |
Small branches of thoracic aorta distributed to the pericardium, in the region of the oblique pericardial sinus, and to posterior mediastinal lymph nodes. Synonym: rami pericardiaci aortae thoracicae. (05 Mar 2000) |
pericardial cavity |
The potential space between the parietal and the visceral layers of the serous pericardium, in the embryo, that part of the primary celom containing the heart; originally it is in open communication with the pericardioperitoneal cavity's and indirectly, through them, with the peritoneal part of the celom. Synonym: cavitas pericardialis, cavum pericardii. (05 Mar 2000) |
pericardial cyst |
<radiology> 90% on right, 25% symptomatic, Differential diagnosis: epicardial lymph node, fat (with or without steroids), Morgagni hernia (12 Dec 1998) |
pericardial decompression |
Incision into the pericardium or aspiration of fluid from pericardium to relieve pressure due to blood or other fluid in the pericardial sac. Synonym: pericardial decompression. (05 Mar 2000) |
pericardial effusion |
<cardiology> A collection of fluid or blood in the pericardial space (inside the pericardial sac) around the heart. Some causes include congestive heart failure, cancer and autoimmune disease. (27 Sep 1997) |
pericardial fremitus |
Vibration in the chest wall produced by the friction of opposing roughened surfaces of the pericardium. See: pericardial rub. (05 Mar 2000) |
pericardial friction sound |
A to-and-fro grating, rasping, or, rarely, creaking sound heard over the heart in some cases of pericarditis, due to rubbing of the inflamed pericardial surfaces as the heart contracts and relaxes; during normal sinus rhythm it is usually triphasic; during any rhythm it may be biphasic or uniphasic. Synonym: pericardial rub, pericardial friction rub. (05 Mar 2000) |
pericardial knock |
An early diastolic sound analogous to the normal third heart sound, but occurring somewhat earlier, due to rapid ventricular filling being abruptly halted by the restricting pericardium; a truly "knocking" quality is uncommon. (05 Mar 2000) |
pericardial murmur |
A friction sound, synchronous with the heart movements, heard in certain cases of pericarditis. (05 Mar 2000) |
pericardial reflex |
A vagal reflex seen during operations involving pericardial manipulation; characterised by signs of vagal stimulation (bradycardia and arterial hypotension). (05 Mar 2000) |
pericardial rub |
A to-and-fro grating, rasping, or, rarely, creaking sound heard over the heart in some cases of pericarditis, due to rubbing of the inflamed pericardial surfaces as the heart contracts and relaxes; during normal sinus rhythm it is usually triphasic; during any rhythm it may be biphasic or uniphasic. Synonym: pericardial rub, pericardial friction rub. (05 Mar 2000) |
pericardial sac |
<anatomy> A tough fibrous membrane that envelops and protects the heart. (27 Sep 1997) |
