Pleural Effusions

Pericardium reflects at the posterior atrioventricular groove.

Pleural effusion continues under the left atrium, posterior to the descendng aorta.

Pericardial Tamponade

Hemodynamics: Comprehensive Echo

Equilibration intracardiac diastolic pressures

usually between 10 and 30 mmHg

Within 44 mmHg

Inspiratory increase in right-sided pressures and reduction in leftsided pressures (pulsus paradoxus)

X - descent

descent of the base in systole

Y - descent

occurs as the tricuspid valve opens and ventricular filling begins from the high-pressure right atrium

in constrictive pericarditis, filling is truncated in early to mid diastole

in tamponade, filling is restricted throughout diastole

Kussmaul‟s Sign

in constriction, venous return increases with inspiration and a high right atrial pressure resists filling resulting in an increased JVP
