| pubmed-article:9769980 | pubmed:abstractText | Constrictive pericarditis was diagnosed in four patients who presented respiratory impairment and pleural effusion, associated with right ventricular failure in two. The cause was probable tuberculosis in two cases, post-irradiation lesions in one and unknown in one. The diagnosis was suspected due to the normal heart volume and pathological electrocardiogram as well as the computed tomographic findings demonstrating pericardial morphology. Right catheterism confirmed the diagnosis: increased right ventricular telediastolic pressure with a dip plateau and equivalent pressures in the right atrium and ventricle. Early diagnosis allowed pericardectomy in two cases. In one case, the subacute epicardopericarditis regressed with corticosteroids and antituberculosis therapy. | lld:pubmed |
