| 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 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) |
| pericardial tamponade | <cardiology> A life-threatening clinical syndrome where there is a large collection of fluid (usually blood) inside the pericardial space that interferes with the haemodynamic performance of the heart. The end result is low blood pressure, shock and death if untreated. (27 Sep 1997) |
| pericardial tap | Needle drainage of the pericardium, usually accompanied by placement of an indwelling catheter for continuing drainage. Synonym: pericardial tap, pericardiocentesis. (05 Mar 2000) |
| pericardial veins | Several small veins from the pericardium emptying into the brachiocephalic veins or superior vena cava. Synonym: venae pericardiacae. (05 Mar 2000) |
| pericardial villi | Minute filiform projections from the surface of the serous pericardium. Synonym: villi pericardiaci. (05 Mar 2000) |
| pericardial window techniques | Surgical construction of an opening or window in the pericardium. It is often called subxiphoid pericardial window technique. (12 Dec 1998) |
