Description
A 65-year-old man presented with symptoms of angina at rest. On evaluation, his ECG showed T wave inversion in the anterior leads. Troponin T was elevated. Echocardiography revealed that the apex and anterior wall of the left ventricle was hypokinetic with normal left ventricular function. Fluoroscopy during the angiogram revealed a stunning image of crescent-shaped extensive pericardial calcification along the right atrium and right ventricle (figure 1, video 1). An extensive crescent-shaped calcification was noted (figure 2, video 2). Extension into the diaphragmatic surface was seen in the lateral view (video 3). The coronary angiogram revealed a triple vessel disease. He was evaluated for pericardial calcification. CT of the chest showed dense pericardial calcification along the right atrium, right ventricle and atrioventricular groove (figure 3). The patient did not give a history of having tuberculosis in the past. Echocardiography was reviewed, which showed that there was no significant respiratory variation in mitral and tricuspid inflow velocities (figures 4 and 5). Tissue Doppler velocities were normal (figures 6 and 7). Hence, constrictive pericarditis was ruled out. There was no evidence of hypercalcaemia or parathyroid abnormality.
The most common cause for pericardial calcification is tuberculosis.1 Whereas in the developed countries, common causes for the same is postsurgery, trauma, uraemia and postradiation and idiopathic.1 The atrioventricular groove is the most common site for pericardial calcification, along with involvement of the inferior and the diaphragmatic portions of the pericardium.1 Pericardial calcification is not pathognomonic of constrictive pericarditis.1 Thirty to 70% of patients with constrictive pericarditis have pericardial calcification.2 In our patient, in spite of having an extensive pericardial calcification, there was no evidence found of constrictive pericarditis on echocardiography.
Learning points
-
Pericardial calcification may be an incidental finding on X-ray or fluoroscopy.
-
The most common cause of pericardial calcification is tuberculosis.
-
Extensive calcification of the pericardium may occur in the absence of constrictive pericarditis.
