Key result
Pericardiectomy cuts RVEDP ~40% and boosts cardiac output in a constrictive pericarditis case.
Why the study?
Data on the hemodynamic and echocardiographic features of constrictive pericarditis during positive pressure mechanical ventilation are incomplete.
Does pericardiectomy improve intraoperative hemodynamic and echocardiographic parameters of cardiac filling in a mechanically ventilated patient with constrictive pericarditis?
Population
1 patient with constrictive pericarditis 6 years after mitral valve replacement
Comparison
Pre-pericardiectomy state vs post-pericardiectomy state during mechanical ventilation
Design
Case report with intraoperative invasive hemodynamic and transesophageal echocardiographic evaluation
Follow-up
Intraoperative

May support hemodynamic benefit of pericardiectomy in constrictive pericarditis; leaves open TEE utility for intraoperative guidance.

Does pericardiectomy improve intraoperative hemodynamic and echocardiographic parameters of cardiac filling in a mechanically ventilated patient with constrictive pericarditis?
Intraoperative transesophageal echocardiography and hemodynamic monitoring during mechanical ventilation can demonstrate the characteristic exaggerated respiratory variation of ventricular filling in constrictive pericarditis, which normalizes following pericardiectomy.
Skubas et al. (2001) conducted a case report in Constrictive pericarditis (n=1). Pericardiectomy vs. Pre-pericardiectomy was evaluated on Intraoperative hemodynamic and echocardiographic features. In a patient with constrictive pericarditis, pericardiectomy reduced right ventricular end-diastolic pressure from 20 to 12 mm Hg and increased cardiac output from 3.8 to 4.9 L/min.
