Key result
Constrictive pericarditis is linked to larger respiratory variation in diastolic pulmonary venous flow vs controls.
Why the study?
The diagnostic value of Doppler pulmonary venous flow assessed by transoesophageal echocardiography in constrictive pericarditis was not fully established.
Does transoesophageal echocardiography assessment of Doppler pulmonary venous flow respiratory variation help identify patients with constrictive pericarditis?
Case-Control (n=25)
Does transoesophageal echocardiography assessment of Doppler pulmonary venous flow respiratory variation help identify patients with constrictive pericarditis?
Absolute Event Rate: -20% vs -9%
p-value: p=<0.05
Transoesophageal Doppler echocardiography reveals that increased respiratory variation in pulmonary venous diastolic flow is a significant marker for constrictive pericarditis.

May support TEE assessment of pulmonary venous flow variation in suspected constrictive pericarditis; leaves open diagnostic utility pending prospective validation.
MEUBURG et al. (1995) conducted a case-control in Constrictive pericarditis (n=25). Constrictive pericarditis vs. Normal subjects was evaluated on Difference between peak velocities of the diastolic wave obtained at the onset of inspiration and irrespective of the respiratory cycle (p=<0.05). Constrictive pericarditis was associated with a significantly larger respiratory variation in the diastolic pulmonary venous flow wave compared to normal subjects (-20% vs -9%, P<0.05).
