Motion of pulmonic valve and constrictive pericarditis.
Extreme respiratory variation in the depth of the "a" wave of the pulmonic valve echo was demonstrated in a patient with constrictive pericarditis; a mechanism for this finding is offered. Disparity in systolic and diastolic ventricular function in constriction is also useful in ruling out restrictive cardiomyopathy.
