Do hemodynamic responses to the valsalva maneuver reflect myocardial dysfunction?

In 14 consecutive patients with varying myocardial function, evaluation of the Valsalva maneuver was performed using aortic pulse pressure decay to investigate a possible quantitative relationship between the pattern of response and the degree of myocardial dysfunction. The aortic pulse pressure response during strain correlated with resting left ventricular end-diastolic pressure and pulmonary wedge pressure but not with resting cardiac output, cardiac index and ejection fraction. Similar results were obtained when several indices characterizing the aortic pulse pressure decay during Valsalva were used together to predict resting hemodynamic data by multiple regression analysis. In conclusion, quantitative aortic pulse pressure decay during the strain phase of the Valsalva maneuver correlated only moderately with hemodynamic indices used to identify myocardial dysfunction. These results raise doubts about the use of the Valsalva maneuver for the evaluation of myocardial dysfunction.

Pericarditis, pericardial effusion, cardiac tamponade, and constriction.

Critical care aspects of pericardial disease are covered, including diagnosis and differential diagnosis of acute pericarditis, pericardial effusion with and without cardiac tamponade, constrictive pericarditis and effusive-constrictive pericarditis. Emphasis is placed on clinical signs and the important invasive and noninvasive diagnostic procedures, particularly various imaging methods (emphasis on echocardiography), electrocardiography, and cardiac catheterization. Medical and surgical therapies are reviewed, and the technique of pericardiocentesis is presented.
