Key result
A high ratio between right ventricular end-diastolic and systolic pressure is a significant characteristic finding in patients with constrictive pericarditis.
Describes the characteristic intracardiac pressure patterns, specifically a high ratio between right ventricular end-diastolic and systolic pressure, in patients with constrictive pericarditis.

RV pressure ratio may aid constrictive pericarditis evaluation; leaves open validation in larger prospective cohorts.
The characteristic intracardiac pressure patterns of four patients with constrictive pericarditis are described. The significance of a high ratio between right ventricular end-diastolic and systolic pressure is demonstrated. Postoperative changes are described in one patient and the mechanism of the production of the pressure patterns is discussed.
