OBJECTIVE To describe the spectrum and clinical implications of echocardiographic findings associated with Wegener granulomatosis. PATIENTS AND METHODS We retrospectively reviewed the clinical records and echocardiographic data of consecutive patients with confirmed Wegener granulomatosis referred to the echocardiography laboratory during the 21-year period from 1976 through 1997. RESULTS Of the 85 patients identified as having confirmed Wegener granulomatosis, 73 (86%) were found to have echocardiographic abnormalities. In 26 (36%) of these 73 patients, lesions appeared directly related to Wegener granulomatosis. We found regional wall motion abnormalities in 17 (65%) of these 26 patients. Left ventricular systolic dysfunction with decreased ejection fraction was found in 13 patients (50%) and pericardial effusion in 5 patients (19%). Other findings included valvulitis, left ventricular aneurysm, and a large intracardiac mass. A significantly increased mortality rate was observed among patients who had cardiac involvement of Wegener granulomatosis found by echocardiography. CONCLUSIONS We found a high frequency of echocardiographic abnormalities that appear to be related to Wegener granulomatosis and associated with increased mortality. Because cardiac involvement in Wegener granulomatosis often is silent and associated with increased morbidity and worse prognosis, echocardiographic screening of patients with active Wegener granulomatosis may be of clinical value.

Criteria for the classification of Wegener's granulomatosis (WG) were developed by comparing 85 patients who had this disease with 722 control patients with other forms of vasculitis. For the traditional format classification, 4 criteria were selected: abnormal urinary sediment (red cell casts or >5 red blood cells per high power field), abnormal findings on chest radiograph (nodules, cavities, or fixed infiltrates), oral ulcers or nasal discharge, and granulomatous inflammation on biopsy. The p...

Objective To examine the outcome in 155 consecutive patients with Wegener's granulomatosis (WG) followed up for a median of 7 years. Methods Treatment was adapted to the activity and extent of disease, with regular evaluation by an interdisciplinary team accompanied by group education about vasculitis. Results The estimated median survival time was 21.7 years (95% confidence interval [95% CI] 15.60–27.86). Twenty-two patients died; 19 deaths were attributable to WG and/or its treatment. Signific...

Sepsis represents the systemic response to infection and is initiated through the effects of one or more components of the invading microorganism. These components may include structural elements (e.g., endotoxin from gram-negative bacteria) or secreted exotoxins (e.g., toxic shock toxin from some Staphylococcus aureus serotypes or streptococcal toxin A from invasive streptococcus A serotypes). These substances are thought to trigger the local and systemic release of endogenous inflammatory medi...

Congestive cardiomyopathy is a highly unusual complication of Wegener's granulomatosis. In this report, we describe a 37-year-old man with histologically proven Wegener's granulomatosis who had two episodes of severe hypokinetic cardiomyopathy that responded well to cyclophosphamide. The theory that cardiomyopathy might be related to cardiac involvement in Wegener's granulomatosis and the beneficial effect of cyclophosphamide in this condition are discussed.

OBJECTIVE: To determine survivorship in Wegener's granulomatosis (WG) in a well-defined multicenter cohort. METHODS: Follow-up was obtained for 77 of the 85 patients enrolled in the 1990 American College of Rheumatology vasculitis classification study. RESULTS: There were 28 deaths (10 females and 18 males) among the 77 patients available for follow-up. Standardized mortality ratios (SMR) were calculated with mortality data from the general population and from this group of patients with WG (an ...

Wegener's granulomatosis is a systemic inflammatory disorder of unknown aetiology. The protean clinical presentations depend on the organ(s) involved and the degree of progression from a local to a systemic arteritis. The development of serological tests (antieutrophil cytoplasmic antibodies) allows easier diagnosis of a disease whose incidence is increasing. This is particularly helpful where the presentation is not classic--for example "overlap syndromes"--or where the disease presents early i...

In a case of Wegener's granulomatosis aortic valve replacement was performed for worsening congestive cardiac failure secondary to aortic incompetence. Two paravalvular lesions and an isolated intraleaflet deficiency of the non-coronary cusp were identified at operation. Histological changes were consistent with a connective tissue disease.

The prevalence of undiagnosed cardiac involvement in granulomatosis with polyangiitis (GPA) is unknown. In this prospective study we investigated the utility of cardiovascular magnetic resonance (CMR) to identify myocardial abnormalities in GPA and their correlation with disease phenotype. Twenty-six patients with GPA and no cardiovascular disease or diabetes mellitus underwent contrast-enhanced CMR, including late gadolinium-enhancement (LGE), T1-mapping for native T1 and extra-cellular volume ...

Background Antineutrophil cytoplasmic antibody (ANCA)-associated pulmonary renal vasculitis is an uncommon disease entity. Its presentation as acute heart failure for the first time in a patient with established coronary artery disease (CAD) is even rarer. We present here a case of such an association and an approach to managing this clinical situation. Case summary A 60-year-old male patient presented to the emergency room with recent-onset dyspnoea New York Heart Association Class IV. He was h...

Infiltrative heart disease is an encompassing term referring to different pathological entities that involve infiltration of the myocardium by either abnormal substances or inflammatory cells. These infiltrates can impair cellular function, induce necrosis and fibrosis, or otherwise disrupt myocardial architecture resulting in a wide spectrum of structural and functional impairment. Depending on the specific disorder and stage of disease, patients may present with minimal cardiac abnormalities, ...

Myocarditis has a spectrum of clinical presentations, ranging from mild to severe; onset of cardiac signs and symptoms may be slow and insidious, leading to a delayed diagnosis, or distinct up to fulminant forms. Myocarditis may also mimic non-inflammatory myocardial diseases. Myocarditis may resolve with symptomatic cardiological heart failure and arrhythmia treatment, recur or progress, in about one-third of biopsy-proven cases, to dilated cardiomyopathy (DCM), sudden or heart failure-related ...

The vasculitides are a heterogeneous group of disorders, characterized by inflammatory cell infiltration and necrosis of blood vessels that cause vascular obstruction or aneurysm formation, affecting various organs such as lungs, kidneys, skin and joints. Cardiac involvement is commonly encountered in primary systemic vasculitis and it is associated with increased morbidity and mortality. Depending on the dominant pathophysiological mechanism, heart complications may manifest in different ways, ...

Background Recent evidence suggests that cardiac involvement in patients with granulomatosis with polyangiitis (GPA) occurs more frequently than previously reported. Multimodality cardiac imaging is gaining attention in the diagnosis, prognostication, and follow-up of such patients; however, the data remain scarce.

Granulomatosis with polyangiitis (GPA, previously known as Wegener’s granulomatosis) is a type of ANCA-associated vasculitis that affects small- to medium-sized vessels. GPA occurs with a prevalence of 24–152:1000000. The disease affects all races at every age. Various factors may have an impact on the etiology of GPA which is treated as an autoimmune disease. Genetic factors, infectious agents (like Staphylococcus aureus), environmental factors (like silica, hydrocarbons, fumes, pesticides, and...
