In 4 critically ill patients with acute rheumatic carditis, valve incompetence, and severe life-threatening cardiac failure, medical treatment consisting of bedrest, oxygen, digitalis, diuretics, and steroids produced little or no clinical improvement. Echocardiography showed that in each patient myocardial function was relatively well preserved despite active rheumatic carditis and the critical clinical state. Emergency valve replacement was performed, and a good clinical result was achieved in all 4 patients.

Two patients are described with acute rheumatic carditis and severe heart failure who failed to respond to aggressive medical treatment with steroids, salicylates, inotropic agents and afterload reduction. In both cases, cardiac catheterization revealed severe aortic and mitral regurgitation with preserved myocardial contractility. Emergency double valve replacement was successfully performed with marked improvement in both patients. The diagnosis and evaluation of the condition, as well as the unique problems confronted in the post-operative course are discussed.

The importance of metals in normal and pathologic cardiovascular function has been recognized. Significant derangements in myocardial Ca2+, Mg2+, and Cu2+ have been reported in ischemic heart injury. We studied 3 groups of hearts: 1) fifteen specimens obtained from patients who had no heart disease, 2) nine specimens from patients who had expired from cyanotic congenital heart disease, and 3) ten specimens from patients who had expired from acute rheumatic heart disease with carditis and severe heart failure. None of the patients had undergone cardiac surgery. Left ventricular lateral wall Mg2+, Ca2+, Cu2+, and Zn2+ contents were measured by atomic absorption spectrometry. The results showed a significant decrease in myocardial Mg2- (Group I 177.06 +/- 32.71; Group II 155.66 +/- 14.79; Group III 149.00 +/- 13.29, p less than 0.05 and p less than 0.01, respectively), and Cu2+ contents (Group I 3.22 +/- 0.37; Group II 2.94 +/- 0.22; Group III 2.56 +/- 0.32, p less than 0.02 and p less than 0.001, respectively), and a rise in myocardial Ca2+ content (Group I 36.06 +/- 10.72; Group II 43.22 +/- 7.01; Group III 46.30 +/- 4.85, p = not significant, and p less than 0.01, respectively). The myocardial Zn2+ content did not change significantly (Group I 26.53 +/- 3.99; Group II 26.00 +/- 4.15; Group III 26.40 +/- 3.53). The myocardial Mg2+/Ca2+ ratio was reduced markedly in both groups (Group I 5.328 +/- 1.879; Group II 3.685 +/- 0.735; Group III 3.135 +/- 0.291, p less than 0.001 for both Groups II and III vs Group I). The latter results correlated closely with the myocardial Mg2+/Ca2+ ratios reported in experimental models in peri-infarction zones. Thus, the myocardium of patients who had expired from cyanotic congenital heart disease and acute rheumatic carditis is jeopardized by ischemia, with metal contents similar to the border areas in myocardial infarction.

The results of 170 emergency heart valve procedures performed during a 4 1/2-year period were analyzed. Five pathological groups of patients were recognized: those with infective endocarditis (Group 1, 28 patients); acute rheumatic carditis (Group 2, 43 patients); previous valve operation (Group 3, 29 patients); acute-on-chronic cardiac disease (Group 4, 67 patients); and miscellaneous conditions (Group 5, 3 patients). Mitral, aortic, and multiple valve procedures were performed on 58, 65, and 44 patients, respectively. The most common functional lesion was regurgitation. Hospital mortality was highest in Groups 3 (34%) and 4 (31%). By contrast, among the hospital survivors, the highest rate of attrition was in Group 2. Myocardial failure was the predominat cause of death. In view of the hopeless prognosis without operation, the 52% overall 3-year actuarial survival is a gratifying salvage. Unnecessary procrastination can only jeopardize the prospects for surgical cure.

Heart transplantation as a treatment for end-stage heart failure has spawned numerous important challenges in patient care. A heart transplant patient with clinically unsuspected acute rheumatic carditis had an ultimately fatal course marked by refractory rejection and early death after transplantation. The patient had several immune abnormalities. Peripheral blood T lymphocytes (CD2+) were significantly elevated (p < 0.05) by flow cytometry in active rheumatic carditis versus 76 healthy individuals. The CD4+:CD8+ T-cell ratio was 5.5:1 in rheumatic disease and only 2.7:1 in healthy individuals. Numbers of peripheral blood B lymphocytes (CD19+), macrophages (CD14+), and interleukin-2 receptor-positive cells (CD25+) were also elevated in rheumatic disease. Natural killer cells (CD16+) were slightly reduced in number and appeared functionally deficient, and antibody-dependent cellular cytotoxicity was also reduced. Immunohistochemically, infiltrating cells in Aschoff lesions of the rheumatic native heart were mainly T cells, with putative TH/I cells predominating. The striking immune accompaniments of acute rheumatic fever may have heralded profound immune-mediated allograft intolerance leading to the patient's demise. Considering the recrudescence of rheumatic heart disease in this country and its remaining worldwide importance, such patients as the one discussed offer daunting clinical challenges when transplantation is an obvious management choice for severe, end-stage dilated cardiomyopathy.

Background. Rheumatic heart disease (RHD) is a leading cause of heart failure in children and young adults worldwide. B-type natriuretic peptide (BNP) is a useful marker of critical pediatric heart disease, and its N-terminal peptide, NT-proBNP, is elevated in congenital and acquired heart disease in children. Aim. To measure NT-proBNP levels as a marker of carditis in children with acute rheumatic carditis, as compared to children with quiescent RHD and healthy controls. Methods. 16 children with acute rheumatic carditis, 33 children with quiescent RHD, and a cohort of 30 healthy children were studied. Transthoracic echocardiography was performed to assess valve and cardiac function. Tissue Doppler echocardiography was performed for E/E' (ratio between mitral inflow E wave and lateral mitral annulus E' wave) and systolic strain. Results. NT-proBNP levels were significantly higher in children with acute rheumatic carditis and dropped with its resolution. Strain and E/E' values were comparable among the three groups. Conclusion. NT-proBNP is significantly elevated in children with acute rheumatic carditis in the acute stage compared to children with quiescent RHD and healthy subjects, in the presence of comparable echocardiographic indices of LV systolic and diastolic function.

Rheumatic fever (RF) remains endemic in many countries and frequently causes heart failure due to severe chronic rheumatic valvular heart disease, which requires surgical treatment. Here, we report on a patient who underwent an elective surgical correction for mitral and aortic valvular heart disease and had a post-operative diagnosis of acute rheumatic carditis. The incidental finding of Aschoff bodies in myocardial biopsies is frequently reported in the nineteenth-century literature, with prevalences as high as 35%, but no clinical or prognostic data on the patients is included. The high frequency of this finding after cardiac surgery in classical reports suggests that these patients were not using secondary prophylaxis for RF. We discuss the clinical diagnosis of acute rheumatic myocarditis in asymptomatic patients and the laboratorial and imaging methods for the diagnosis of acute rheumatic carditis. We also discuss the prognostic implications of this finding and review the related literature.
