Abstract

Sarcoidosis is a rare granulomatous disease of unknown etiology that can affect any organ. Cardiac involvement, although uncommon, has a wide spectrum of clinical manifestations and is potentially fatal. Although there is no agreement upon a strategy for the diagnosis (which is difficult to make based on clinical information alone), the introduction of newer technology is promising and may be useful both for the early diagnosis of cardiac involvement and for the evaluation of response to therapy.

Early treatment is crucial in improving symptoms and prognosis. ICD implantation and cardiac transplantation may offer improvements in management, as steroid therapy and pacemaker implantation has led to improved outcomes over the past three decades.

Introduction

Sarcoidosis is a multisystem, granulomatous disease of unknown etiology often seen in young adults. Age-adjusted annual incidence rate in the United States is 35.5 per 100,000 for blacks and 10.9 per 100,000 for whites with an overall prevalence rate of approximately 20 per 100,000 population [1]. Higher prevalence rates have been reported in Japan and some northern European countries such as Sweden.

Three separate clinicians initially described the disease in the 19th century in Europe [2]. In 1899, Boeck first used the word “sarkoid” to describe a cutaneous lesion because of the histological similarity (but favorable course) to sarcoma [3].

Etiology

The current evidence suggest that sarcoidosis results from an exaggerated cellular immune response to a variety of antigens or self-antigens which cause CD4 (helper–inducer) T-cell accumulation, activation and release of inflammatory cytokines eventually leading to granuloma formation [4] Fig. 1, Fig. 2. The disease may affect almost any organ and is characterized classically by the presence of non-caseating granulomas composed mainly of an aggregate of epithelioid cells and Langhans or foreign

Cardiac sarcoidosis

Although the respiratory tract and the lymphatic system are most often affected, the clinical manifestation of sarcoidosis can be widespread and may involve any organ system. The first case of cardiac sarcoidosis was reported in 1929 when Bernstein described sarcoid granulomas involving the pericardium [8]. Since then a wide range of cardiac manifestations of the disease has been described including conduction abnormalities, mitral regurgitation, congestive heart failure (CHF), ventricular

Diagnostic approach

Hugh Fleming, a cardiologist from England who specialized in the study of cardiac sarcoidosis, wrote in 1981 “the recognition of sarcoid heart disease …suggests that many of us have had, and many indeed still have, a blind spot for this diagnosis” [14]. More than 20 years passed since that statement and the diagnosis of cardiac sarcoidosis still a challenge for physicians.

To diagnose sarcoidosis in general, the American Thoracic Society (ATS) recommended the presence of a compatible clinical

Treatment

The treatment strategy of cardiac sarcoidosis should aim at relieving symptoms, controlling the inflammatory process, preventing further deterioration in myocardial function and preventing sudden death. Physicians should not wait until the onset of symptoms to start therapy; the treatment should be started as soon as the diagnosis is made.

Prognosis

The natural history and prognosis of sarcoidosis is difficult to determine due to the variable clinical presentations and severity of the disease, other organ involvement, the waxing and waning nature of the disease, and variable responses to steroid therapy in individual patients.

In the absence of cardiac involvement, the mortality rate of sarcoidosis is about 1–5% per year [73], [87]. Cardiac involvement associated with poorer prognosis and the mortality rate may exceed 40% at 5 years and 55%

      The proposed mechanism for SVT is atrial dilation or cor pulmonale from pulmonary involvement [9]. Alternatively, focal granulomatous infiltration of atrial myocardium serving as a nidus for ectopy has been proposed as a mechanism for CS-related atrial fibrillation or atrial flutter [8,9,20]. Most patients with CS and SVTs are symptomatic (96%), therefore screening asymptomatic patients for the detection of underlying SVTs is not warranted [9].
