Patients and Methods
We retrospectively analyzed the clinical reports of 51 consecutive patients (38 males, 13 females; age 40.1 ± 15.5 years; range 13 to 73 years) with constrictive pericarditis who underwent surgery from January 2005 to January 2011 in our single-center institution. Our institutional ethics committee approved the present study and all patients gave written informed consent.
The diagnosis of constrictive pericarditis was made according to the combination of Doppler echocardiography (thickened or
Results
Table 1 lists the causes of constriction in the series. Of the 51 patients, 33 patients (65%) had Tb constrictive pericarditis and 13 (25%) had idiopathic constrictive pericarditis. Underlying conditions were previous cardiac surgery for 3 patients (6%) and connective tissue disease for 1 patient (2%). The remaining patient had chest trauma 40years ago.
The average pulse pressure was 34 ± 8 mm Hg, and the mean heart rate was 100 ± 14 beats per minute. When classifying patients using the
Comment
Constrictive pericarditis is an uncommon condition involving impaired mid and late ventricular filling due to a thickened or noncompliant pericardium. The most important findings of our evaluation were that clinical manifestations could worsen, even with short durations of symptoms, and thus timely diagnosis and prompt treatment are important to improved prognosis.
Our results are consistent with previous studies, which showed that constriction was more common in males [7, 12, 20]. While there
