Does pericardiotomy alter hemodynamics and echocardiographic parameters in patients with severe chronic pulmonary hypertension and right ventricular hypertrophy?
The human pericardium adapts over time to chronic right ventricular pressure overload and cardiomegaly, exerting little restrictive influence on cardiac hemodynamics.
Blanchard et al. (1992) conducted an observational in Right ventricular hypertrophy and cardiomegaly secondary to chronic pulmonary thromboembolic disease and severe pulmonary hypertension (n=14). Pericardiotomy vs. Before pericardiotomy (intact pericardium) was evaluated on Hemodynamic and echocardiographic variables. Pericardiotomy produced no significant changes in hemodynamic or echocardiographic parameters in patients with chronic severe right ventricular pressure overload and cardiomegaly.
