Constrictive pericarditis causing extrinsic mitral stenosis and a left heart mass

Abstract

Summary: Constrictive pencarditis is a fibrotic process involving both layers of the pericardium and is known to give rise to obstruction to blood flow in the right heart, We report a patient with constrictive pericarditis who had echocardiographic features of mitral stenosis caused by a fibrocalcific mass lesion involving the mitral annulus with infiltration into the base ofthe posterior mitral leaflet. To our knowledge, this has not been reported in the literature.

Constrictive Pericarditis with a Calcific Mass Invading into the Right Ventricular Myocardium

“…Constrictive pericarditis with mass formation is a rare occurrence, with few cases noted in the literature. Mass formation has been reported to be caused by hematoma, calcified hematoma, calcified tissue, tumor, and infection . Pus‐filled mass formation by gram positive, gram negative, mycobacterial species, as well as sterile acellular debris containing cholesterol, calcium, and fatty acids, has been reported in various cases .…”

“…[3][4][5][6][7][8][9][10] Pusfilled mass formation by gram positive, gram negative, mycobacterial species, as well as sterile acellular debris containing cholesterol, calcium, and fatty acids, has been reported in various cases. [4][5][6][7]10 Very rarely, constrictive pericarditis with mass formation can invade the myocardium. A case of calcific constrictive pericarditis was reported with calcific invasion into the myocardium of the left ventricle, but it did not necessitate surgical reinforcement of the residual myocardium.…”
