Hemodynamic Effects of Catecholamine
Cardiac hemodynamic studies during control resting state and isoproterenol infusion were performed on five patients with constrictive pericarditis. During isoproterenol infusion, stroke volume increased by 60%, while there was no significant change in pulmonary wedge and right atrial mean pressures. The relatively fixed filling pressure is the indirect evidence of fixed diastolic size of the he...

The hemodynamic findings in five patients are presented in order to demonstrate the variability in the clinical and physiologic patterns that may be encountered in restrictive disease of the pericardium. The mechanical effects of pericardial encasement previously described were confirmed. Furthermore, it was found that myocardial insufficiency and hypervolemia were not only important causative ...
متن کاملConstrictive pericarditis in a 19-month-old child.
We report a case of chronic nonspecific constrictive pericarditis with myocardial involvement in a 19-month-old infant. The patient underwent total pericardiectomy and had irreversible hemodynamic instability. Constrictive pericarditis is rare in childhood. It may follow several processes, most frequently an infectious disease. The natural course of the disease consists of progressive myocardia...
متن کاملConstrictive Pericarditis as a Never Ending Story: What's New?
Nowadays, we have a better understanding of the natural history of constrictive pericarditis such as transient constriction. In addition, we have acquired the correct understanding of hemodynamic features that are unique to constrictive pericarditis. This understanding has allowed us to diagnose constrictive pericarditis reliably with Doppler echocardiography and differentiation between constri...
متن کاملHemodynamic studies following pericardiectomy for constrictive pericarditis.
PERICARDIECTOMY for constrictive pericarditis was first successfully performed just over 50 years ago' and has subsequently become the accepted definitive method of treatment. Postoperative clinical evaluations during this time have indicated good to excellent results in the majority of patients.2 8 Despite the wide use of cardiac catheterization in the preoperative evaluation of patients with ...
