The role of cardiac MR in identifying annulus paradoxus, a specific marker for constrictive pericarditis
Background Distinguishing constrictive pericarditis from restrictive cardiomyopathy can be challanging. In normal subjects and many cardiac pathologies, the lateral mitral annulus compared to medial demonstrates more longitudinal excursion. This is due to the presence of more longitudinal fibres and lubrication offered by pericardium. Annulus paradoxus is a term used to define reversal of this ...
متن کاملPulsus paradoxus.
Systolic blood pressure normally falls during quiet inspiration in normal individuals. Pulsus paradoxus is defined as a fall of systolic blood pressure of >10 mmHg during the inspiratory phase. Pulsus paradoxus can be observed in cardiac tamponade and in conditions where intrathoracic pressure swings are exaggerated or the right ventricle is distended, such as severe acute asthma or exacerbatio...

was 80/40 mmHg. The electrocardiogram showed sinus rhythm (90 bpm) with no signs of myocardial ischaemia. Consciousness returned within few seconds, and full consciousness was achieved after 3 min. The BP recovered over time. A computed tomography scan was then performed to investigate the thoracic aorta. Slight pericardial and bilateral pleural effusions were observed with a normal aorta and n...
متن کاملAnnulus paradoxus: transmitral flow velocity to mitral annular velocity ratio is inversely proportional to pulmonary capillary wedge pressure in patients with constrictive pericarditis.
BACKGROUND The early diastolic velocity of the mitral annulus (E') is reduced in patients with diastolic dysfunction and increased filling pressures. Because transmitral inflow early velocity (E) increases progressively with higher filling pressures, E/E' has been shown to have a strong positive relationship with pulmonary capillary wedge pressure (PCWP) and left ventricular end-diastolic press...
متن کاملClinical signs in medicine: pulsus paradoxus.
Historical Aspects The reduction in pulse volume during inspiration was first described by Lomer in 1669 in constrictive pericarditis1. A similar finding was described by Floyer and later by William in 1850 in bronchial asthma1. Adolf Kussmaul (Freiberg, Germany) coined the term pulsus paradoxus in 1873 in three patients with constrictive pericarditis. The paradox was: (1) the discrepancy b...
